Forms

Terminology: the Forms and the forms

The English word "form" may be used to translate two distinct concepts with which Plato was concerned—the outward "form" or appearance of something , and "Form" in a new, technical sense, apparently invented by Plato. These are often distinguished by the use of uncapitalized "form" and capitalized "Form," respectively. In the following summary passage, the two concepts are related to each other:[7]

Suppose a person were to make all kinds of figures of gold...—somebody points to one of them and asks what it is. By far the safest and truest answer is [to say] that it is gold; and not to call the triangle or any other figures which are formed in the gold "these" as though they had existence; and the same argument applies to the universal nature which receives all bodies —that must always be called the same; for, while receiving all things, she never departs at all from her own nature, and never...assumes a form like that of any of the things which enter into her; ... But the forms which enter into and go out of her are the likenesses of real existences modelled after their patterns in a wonderful and inexplicable manner....

The forms that we see, according to Plato Plato , was a Classical Greek philosopher, mathematician, writer of philosophical dialogues, and founder of the Academy in Athens, the first institution of higher learning in the Western world. Along with his mentor, Socrates, and his student, Aristotle, Plato helped to lay the foundations of natural philosophy, science, and Western philosophy, are not real, but literally mimic the real Forms. In the allegory of the cave The Allegory of the Cave, also commonly known as Myth of the Cave, Metaphor of the Cave, The Cave Analogy, Plato's Cave or the Parable of the Cave, is an allegory used by the Greek philosopher Plato in his work The Republic to illustrate "our nature in its education and want of education". The allegory of the cave is written as a expressed in Republic The Republic is a Socratic dialogue by Plato, written c. 380 B.C.E.. It is one of the most influential works of philosophy and political theory, and Plato's best known work. In Plato's fictional dialogues the characters of Socrates as well as various Athenians and foreigners discuss the meaning of justice and examine whether the just man is, the things we ordinarily perceive in the world are characterized as shadows of the real things, which we do not perceive directly. That which the observer understands when he views the world mimics the archetypes An archetype is an original model of a person, ideal example, or a prototype upon which others are copied, patterned, or emulated; a symbol universally recognized by all. In psychology, an archetype is a model of a person, personality, or behavior of the many types In metaphysics, a type is a category of being. Human is a type of thing; cloud is a type of thing ; and so on. A particular instance of a type is called a token of that thing; so Socrates was a token of a human being, but is not any longer since he is dead. Likewise, the capital A in this sentence is a token of the first letter of the Latin and properties In metaphysics , the different kinds or ways of being are called categories of being or simply categories. According to the Aristotelian tradition, a being is anything that can be said to be in the various senses of this word. Hence, to investigate the categories of being is to determine the most fundamental senses in which things can be said to (that is, of universals In metaphysics, a universal is what particular things have in common, namely characteristics or qualities. In other words, universals are repeatable or recurrent entities that can be instantiated or exemplified by many particular things. For example, suppose there are two chairs in a room, each of which is green. These two chairs both share the) of things we see all around us.

What are the Forms?

The Greek concept of form precedes the attested language and is represented by a number of words mainly having to do with vision: the sight or appearance of a thing. The main words, εἶδος (eidos) and ἰδέα (idea)[8] come from the Indo-European The Indo-European languages are a family of several hundred related languages and dialects, including most major languages of Europe, Iran, and India, and historically also predominant in Anatolia and Central Asia. Attested since the Bronze Age, in the form of Mycenaean Greek and Anatolian languages, the Indo-European family is significant to the root *weid-, "see".[9] Both words are in the works of Homer Homer is a legendary ancient Greek epic poet, traditionally said to be the author of the epic poems the Iliad and the Odyssey. The ancient Greeks generally believed that Homer was an historical individual, but modern scholars are skeptical: no reliable biographical information has been handed down from classical antiquity, and the poems themselves, the earliest Greek literature. Equally ancient is μορφή (morphē), "shape", from an obscure root. The φαινόμενα (phainomena), "appearances", from φαίνω (phainō), "shine", Indo-European *bhā-,[10] was a synonym.

These meanings remained the same over the centuries until the beginning of philosophy, when they became equivocal, acquiring additional specialized philosophic meanings. The pre-Socratic philosophers Pre-Socratic philosophy is Greek philosophy before Socrates. In Classical antiquity, the pre-Socratic philosophers were called physiologoi . Diogenes Laërtius divides the physiologoi into two groups, Ionian and Italiote, led by Anaximander and Pythagoras, respectively, starting with Thales Thales of Miletus (Θαλής,Thales,Thalês , ca. 624 BC–ca. 546 BC), was a pre-Socratic Greek philosopher from Miletus in Asia Minor, and one of the Seven Sages of Greece. Many, most notably Aristotle, regard him as the first philosopher in the Greek tradition. According to Bertrand Russell, "Western philosophy begins with Thales.", noted that appearances change quite a bit and began to ask what the thing changing "really" is. The answer was substance Substance theory, or substance attribute theory, is an ontological theory about objecthood, positing that a substance is distinct from its properties. This is part of essentialism in that ousia as a substance can also be a descriptor of an object's being and/or nature. As substance or ousia is a permanent property of an object without which the, which stands under the changes and is the actually existing thing being seen. The status of appearances now came into question. What is the form really and how is that related to substance?

Thus the theory of matter and form (today's hylomorphism Hylomorphism is a philosophical theory developed by Aristotle, which analyzes substance into matter and form. More precisely, substances are conceived of as forms inhering in matter) was born. Starting with at least Plato and possibly germinal in some of the presocratics the forms were considered "in" something else, which Plato called nature (phusis). The latter seemed as a "mother" (matter Matter is the substrate from which physical existence is derived, remaining more or less constant amid changes. The word "matter" is derived from the Latin word māteria, meaning "wood" in the sense "material", as distinct from "mind" or "form" from mater)[11] of substances by receiving (or losing) forms.

But what were the forms? In Plato as well as in general speech there is a form for every object or quality in reality: forms of dogs, human beings, mountains, colors, courage, love, and goodness. Form answers the question "what is that?" Plato was going a step further and asking what Form itself is. He supposed that the object was essentially or "really" the Form and that the phenomena were mere shadows mimicking the Form; that is, momentary portrayals of the Form under different circumstances. The problem of universals The problem of universals is an ancient problem in metaphysics about whether universals exist. Universals are general or abstract qualities, characteristics, properties, kinds or relations, such as being male/female, solid/liquid/gas or a certain colour, that can be predicated of individuals or particulars or that individuals or particulars can be - how can one thing in general be many things in particular - was solved by presuming that Form was a distinct singular thing but caused plural representations of itself in particular objects.[12] Matter was considered particular in itself.

These Forms are the essences of various objects: they are that without which a thing would not be the kind of thing it is. For example, there are countless tables in the world but the Form of tableness is at the core; it is the essence of all of them.[13] Plato held that the world of Forms is separate from our own world (the world of substances) and also is the true basis of reality. Removed from matter, Forms are the most pure of all things. Furthermore, Plato believed that true knowledge/intelligence is the ability to grasp the world of Forms with one's mind.[14]

A Form is aspatial (outside the world) and atemporal (outside time). Atemporal means that it does not exist within any time period. It did not start, there is no duration in time, and it will not end. It is neither eternal in the sense of existing forever or mortal, of limited duration. It exists outside time altogether.[15] Forms are aspatial in that they have no spatial dimensions, and thus no orientation in space, nor do they even (like the point) have a location.[16] They are non-physical, but they are not in the mind. Forms are extra-mental.[17]

A Form is an objective "blueprint" of perfection.[18] The Forms are perfect themselves because they are unchanging. For example, say we have a triangle drawn on a blackboard. A triangle is a polygon with 3 sides. The triangle as it is on the blackboard is far from perfect. However, it is only the intelligibility of the Form "triangle" that allows us to know the drawing on the chalkboard is a triangle, and the Form "triangle" is perfect and unchanging. It is exactly the same whenever anyone chooses to consider it; however, the time is that of the observer and not of the triangle.

The "Intelligible Realm"

Plato often invokes, particularly in the Phaedo Plato's Phaedo is one of the great dialogues of his middle period, along with the Republic and the Symposium. The Phaedo, which depicts the death of Socrates, is also Plato's fifth and last dialogue (the first four being Euthyphro, Meno, Apology, and Crito) to detail the philosopher's final days. The dialogue is told from the perspective of one of, Republic The Republic is a Socratic dialogue by Plato, written c. 380 B.C.E.. It is one of the most influential works of philosophy and political theory, and Plato's best known work. In Plato's fictional dialogues the characters of Socrates as well as various Athenians and foreigners discuss the meaning of justice and examine whether the just man is and Phaedrus The Phaedrus , written by Plato, is a dialogue between Plato's main protagonist, Socrates, and Phaedrus, an interlocutor in several dialogues. The Phaedrus was presumably composed around 370 BC, around the same time as Plato's Republic and Symposium; with those two texts, it is often considered one of Plato's literary high points. Although, poetic language to illustrate the mode in which the Forms are said to exist. Near the end of the Phaedo, for example, Plato describes the world of Forms as a pristine region of the physical universe located above the surface of the Earth (Phd. 109a-111c). In the Phaedrus the Forms are in a "place beyond heaven" (Phdr. 247c ff); and in the Republic the sensible world is contrasted with the intelligible world in the famous allegory of the cave The Allegory of the Cave, also commonly known as Myth of the Cave, Metaphor of the Cave, The Cave Analogy, Plato's Cave or the Parable of the Cave, is an allegory used by the Greek philosopher Plato in his work The Republic to illustrate "our nature in its education and want of education". The allegory of the cave is written as a.

It would be a mistake, however, to take Plato's imagery literally.[19] Plato emphasizes that the Forms are not beings which are extended in space (or time), but rather subsist in a more abstract way. Such we read in the Symposium of the Form of Beauty: "It is not anywhere in another thing, as in an animal, or in earth, or in heaven, or in anything else, but itself by itself with itself," (211b). And in the Timaeus Plato writes: "Since these things are so, we must agree that that which keeps its own form unchangingly, which has not been brought into being and is not destroyed, which neither receives into itself anything else from anywhere else, nor itself enters into anything anywhere, is one thing," (52a, emphasis added).

The ideal state

Plato postulated a world of ideal Forms, which he admitted were impossible to know. Nevertheless he formulated a very specific description of that world, which did not match his metaphysical principles. Corresponding to the world of Forms is our world, that of the mimes, a corruption of the real one. This world was created by the Good according to the patterns of the Forms. Man's proper service to the Good is cooperation in the implementation of the ideal in the world of shadows; that is, in miming the Good.

To this end Plato wrote Republic detailing the proper imitation of the Good, despite his admission that Justice, Beauty, Courage, Temperance, etc., cannot be known. Apparently they can be known to some degree through the copies with great difficulty and to varying degrees by persons of varying ability.

The republic is a greater imitation of Justice:[20]

Our aim in founding the state was not the disproportional happiness of any one class,[21] but the greatest happiness of the whole; we thought that in a state which is ordered with a view to the good of the whole we should be most likely to find justice.

The key to not know how such a state might come into existence is the word "founding" (oikidzomen), which is used of colonization. It was customary in such instances to receive a constitution from an elected or appointed lawgiver; however in Athens, lawgivers were appointed to reform the constitution from time to time (for example, Draco Draco was the first legislator of ancient Athens, Greece, 7th century BC, Solon Solon was an Athenian statesman, lawmaker, and elegiac poet. He is remembered particularly for his efforts to legislate against political, economic and moral decline in archaic Athens. His reforms failed in the short term yet he is often credited with having laid the foundations for Athenian democracy). In speaking of reform, Socrates uses the word "purge" (diakathairountes)[22] in the same sense that Forms exist purged of matter.

The purged society is a regulated one presided over by academics created by means of state education, who maintain three non-hereditary classes[23] as required: the tradesmen (including merchants and professionals), the guardians (militia and police) and the philosophers (legislators, administrators and the philosopher-king). Class is assigned at the end of education, when the state sets individuals up in their occupation. Plato expects class to be hereditary but he allows for mobility according to natural ability. The criteria for selection by the academics is ability to perceive forms (the analog of English "intelligence") and martial spirit as well as predisposition or aptitude.

The views of Socrates on the proper order of society are certainly contrary to Athenian values of the time and must have produced a shock effect, intentional or not, accounting for the animosity against him. For example, reproduction is much too important to be left in the hands of untrained individuals: "... the possession of women and the procreation of children ... will ... follow the general principle that friends have all things in common, ...."[24] The family is therefore to be abolished and the children - whatever their parentage - to be raised by the appointed mentors of the state.

Their genetic fitness is to be monitored by the physicians: "... he (Asclepius Asclepius is the god of medicine and healing in ancient Greek religion. Asclepius represents the healing aspect of the medical arts; his daughters are Hygieia ("Health"), Iaso ("Medicine"), Aceso ("Healing"), Aglæa/Ægle ("Healthy Glow"), and Panacea ("Universal Remedy"). The rod of Asclepius, a, a culture hero) did not want to lengthen out good-for-nothing lives, or have weak fathers begetting weaker sons - if a man was not able to live in the ordinary way he had no business to cure him ...."[25] Physicians minister to the healthy rather than cure the sick: "... (Physicians) will minister to better natures, giving health both of soul and of body; but those who are diseased in their bodies they will leave to die, and the corrupt and incurable souls they will put an end to themselves."[26] Nothing at all in Greek medicine so far as can be known supports the airy (in the Athenian view) propositions of Socrates. Yet it is hard to be sure of Socrates' real views considering that there are no works written by Socrates himself. There are two common ideas pertaining to the beliefs and character of Socrates: the first being the Mouthpiece Theory where writers use Socrates in dialog as a mouthpiece to get their own views across. However, since most of what we know about Socrates comes from plays most of the Platonic plays are accepted as the more accurate Socrates since Plato was a direct student of Socrates.

Many other principles of the ideal state are expressed: the activities of the populace are to be confined to their occupation and only one occupation is allowed (only the philosophers may be generalists). The citizens must not meddle in affairs that are not their business, such as legislation and administration (a hit at democracy). Wealth is to be allowed to the tradesmen only. The marketplace must not be regulated but left up to them. The guardians and the philosophers are not to own fine homes or cash reserves but receive a small pension from the state. None of these items are consistent with an unknowable Good.

Perhaps the most important principle is that just as the Good must be supreme so must its image, the state, take precedence over individuals in everything. For example, guardians "... will have to be watched at every age in order that we may see whether they preserve their resolution and never, under the influence either of force or enchantment, forget or cast off their sense of duty to the state."[27] This concept of requiring guardians of guardians perhaps suffers from the Third Man weakness (see below): guardians require guardians require guardians, ad infinitum. The ultimate trusty guardian is missing. Socrates does not hesitate to face governmental issues many later governors have found formidable: "Then if anyone at all is to have the privilege of lying, the rulers of the state should be the persons, and they ... may be allowed to lie for the public good."[28]

All ideal beliefs are all fixed and universal, and living in the ideal world called: Hyperuranium.

Evidence of Forms

Plato's main evidence for the existence of Forms is intuitive Intuition is the apparent ability to acquire knowledge without inference or the use of reason. “The word ‘intuition’ comes from the Latin word 'intueri', which is often roughly translated as meaning ‘to look inside’ or ‘to contemplate’." Intuition provides us with beliefs that we cannot necessarily justify. For this reason, it only and is as follows.

The argument from human perception

We call both the sky and blue jeans by the same color: Blue. However, clearly a pair of jeans and the sky are not the same color; moreover, the wavelengths of light reflected by the sky at every location and all the millions of blue jeans in every state of fading constantly change, and yet we somehow have an idea of the basic form Blueness as it applies to them. Says Plato:[29][30]

But if the very nature of knowledge changes, at the time when the change occurs there will be no knowledge, and, according to this view, there will be no one to know and nothing to be known: but if that which knows and that which is known exist ever, and the beautiful and the good and every other thing also exist, then I do not think that they can resemble a process of flux, as we were just now supposing.

The argument from perfection

No one has ever seen a perfect The term "perfection" is actually used to designate a range of diverse, if often kindred, concepts. These concepts have historically been addressed in a number of discrete disciplines, notably mathematics, physics, chemistry, ethics, aesthetics, ontology, and theology circle, nor a perfectly straight line, yet everyone knows what a circle and a straight line are. Plato utilizes the tool-maker's blueprint as evidence that Forms are real:[31]

... when a man has discovered the instrument which is naturally adapted to each work, he must express this natural form, and not others which he fancies, in the material ....

Perceived circles or lines are not exactly circular or straight, and true circles and lines could never be detected since by definition they are sets of infinitely small points. But if the perfect ones were not real, how could they direct the manufacturer?

Criticisms of Platonic Forms

Self-criticism

Plato was well aware of the limitations of his theory, as he offered his own criticisms of it in his dialogue Parmenides Parmenides is one of the dialogues of Plato. It is widely considered to be one of, if not the most, challenging and enigmatic of Plato's dialogues. There Socrates is portrayed as a young philosopher acting as junior counterfoil to aged Parmenides. To a certain extent it is tongue-in-cheek as the older Socrates will have solutions to some of the problems that are made to puzzle the younger.[citation needed]

The dialogue does present a very real difficulty with the Theory of Forms, which was overcome later by Aristotle,[citation needed] but not without rejecting the independently existing world of Forms. It is debated whether Plato viewed these criticisms as conclusively disproving the Theory of Forms. It is worth noting that Aristotle was a student and then a junior colleague of Plato; it is entirely possible that the presentation of Parmenides "sets up" for Aristotle; that is, they agreed to disagree.

The difficulty lies in the conceptualization of the "participation" of an object in a form (or Form). The young Socrates conceives of his solution to the problem of the universals in another metaphor, which though wonderfully apt, remains to be elucidated:[32]

Nay, but the idea may be like the day which is one and the same in many places at once, and yet continuous with itself; in this way each idea may be one and the same in all at the same time.

But exactly how is a Form like the day in being everywhere at once? The solution calls for a distinct form, in which the particular instances, which are not identical to the form, participate; i.e., the form is shared out somehow like the day to many places. The concept of "participate", represented in Greek by more than one word, is as obscure in Greek as it is in English. Plato hypothesized that distinctness meant existence as an independent being, thus opening himself up to the famous third man argument The Third Man Argument , first offered by Plato in his dialogue Parmenides, is a philosophical criticism of Plato's own Theory of Forms. The argument posits that if a man is a man because he partakes in the form of man, then a third form would be required to explain how man and the form of man are both man of Parmenides,[33] which proves that forms cannot independently exist and be participated.[34]

If universal and particulars - say man or greatness - all exist and are the same then the Form is not one but is multiple. If they are only like each other then they contain a form that is the same and others that are different. Thus if the Form and a particular are alike then there must be another, or third, man or greatness by possession of which they are alike. An infinite regression An infinite regress in a series of propositions arises if the truth of proposition P1 requires the support of proposition P2, and for any proposition in the series Pn, the truth of Pn requires the support of the truth of Pn+1. There would never be adequate support for P1, because the infinite sequence needed to provide such support could not be must result (consequently the mathematicians often call the argument the Third Man Regression); that is, an endless series of third men. The ultimate participant, greatness, rendering the entire series great, is missing. Moreover, any Form is not unitary but is composed of infinite parts, none of which is the proper Form.

The young Socrates (some may say the young Plato) did not give up the Theory of Forms over the Third Man but took another tack, that the particulars do not exist as such. Whatever they are, they "mime" the Forms, appearing to be particulars. This is a clear dip into representationalism Representational realism, related to indirect realism, is a philosophical concept, broadly equivalent to the accepted view of perception in natural science. Unfortunately, the meaning of the theory is dependent on the user's pre-interpretation of words like 'perceive', 'reality' etc. such that in the longstanding debate between representational, that we cannot observe the objects as they are in themselves but only their representations. That view has the weakness that if only the mimes can be observed then the real Forms cannot be known at all and the observer can have no idea of what the representations are supposed to represent or that they are representations.

Plato's later answer would be that men already know the Forms because they were in the world of Forms before birth. The mimes only recall these Forms to memory.[35] Science Science is, in its broadest sense, any systematic knowledge-base or prescriptive practice that is capable of resulting in a prediction or predictable type of outcome. In this sense, science may refer to a highly skilled technique or practice would certainly reject the unverifiable and in ancient times investigative men such as Aristotle mistrusted the whole idea. The comedian Aristophanes Aristophanes , son of Philippus, of the deme Cydathenaus, was a prolific and much acclaimed comic playwright of ancient Athens. Eleven of his forty plays survive virtually complete. These, together with fragments of some of his other plays, provide us with the only real examples we have of a genre of comic drama known as Old Comedy, and they are wrote a play, the Clouds The Clouds is a comedy written by the celebrated playwright Aristophanes lampooning intellectual fashions in classical Athens. It was originally produced at the City Dionysia in 423 BC and it was not well received, coming last of the three plays competing at the festival that year. It was revised some time between 420-417 BC and thereafter it was, poking fun of Socrates with his head in the clouds.

Aristotelian criticism

This article needs additional citations for verification. Please help improve this article by adding reliable references. Unsourced material may be and removed. (September 2008)

The topic of Aristotelian criticism of Plato's Theory of Forms is a large one and continues to expand. Aristotle did not just criticise Plato but Platonism typically without distinguishing individuals. Moreover, rather than quote Plato he chose to summarize him often in one-liners not comprehensible without considerable exegesis and sometimes not then. As a historian of prior thought Aristotle often uses the prior arguments as a foil to present his own ideas. Consequently, in presenting the Aristotelian criticisms it is necessary to distinguish what Aristotle wrote, what he meant, whether Plato meant that, whether valid and what the relationship to Aristotle's concepts: a formidable task extending over centuries of scholarship. This article presents a few sample arguments addressed by a few sample scholars. Readers may pursue the topic more fully through the citations and bibliography.

In the summary passage quoted above[7] Plato distinguishes between real and non-real "existing things", where the latter term is used of substance. The figures, which the artificer places in the gold, are not substance, but gold is. Aristotle, after stating that according to Plato all things studied by the sciences have Form, asserts that Plato considered only substance to have Form, giving rise to the contradiction of Forms existing as the objects of the sciences but not existing as non-substance.[36]

Despite Ross's objection that Aristotle is wrong, that Plato considers many non-substances to be Forms, such as Sameness, Difference, Rest, Motion, the criticism remains and is major. Ross's summary dismissal: "We need not concern ourselves with Aristotle's argument" is hasty. Plato did not know where to draw the line between Form and non-Form. As Cornford points out,[37] things about which the young Socrates (and Plato) asserted "I have often been puzzled about these things"[38] referring to Man, Fire and Water, appear as Forms in his later works, but others do not, such as Hair, Mud, Dirt, about which Socrates is made to assert: "it would be too absurd to suppose that they have a Form." Aristotle's thought distinguishes between accidental and essential form.[39]

Another argument of Aristotle attacked by Ross[36] is that Socrates posits a Form, Otherness, to account for the differences between Forms. Apparently Otherness is existing non-existence: the Not-tall, the Not-beautiful, etc., so that every particular object participates in a Form causing it not to be one essence; that is, a Form to exclude the essence but allow all others. According to Ross, however, Plato never made the leap from "A is not B" to "A is Not-B." Otherness only applies to its own particulars and not to the other Forms; for example, there is no Form, Non-Greek, only particulars of Otherness that suppress Greek.

This objection does not evade the question. Whether or not Socrates meant that the particulars of Otherness are Not-Greek, Not-tall, Not-beautiful, etc., such a particular still operates only on specific essences. If it were a general exclusiveness every Form would be excluded and nothing be anything in particular. If the exclusion excludes one essence then either Otherness is not unitary or multiple Othernesses exist, each one excluding one essence. It is something and it is not something; it allows and does not allow, which are contradictory properties of the one Form.

Though familiar with insight An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German word Aha-Erlebnis. The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany, Plato had postulated that we know Forms through remembrance. Aristotle Aristotle (384 BC – 322 BC) was a Greek philosopher, a student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, politics, government, ethics, biology, and zoology. Together with Plato and Socrates (Plato's teacher), Aristotle is one of the most successfully makes epistemological Epistemology or theory of knowledge is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. It addresses the questions: arguments against this view. In Plato the particulars do not really exist. Countering "... for that which is non-existent cannot be known"[40] Aristotle points out that proof rests on prior knowledge of universals and that if we did not know what universals are we would have no idea of what we were trying to prove and could not be trying to prove it. Knowledge of the universal is given from even one particular; in fact, the inductive Inductive reasoning, also known as induction or inductive logic, is a type of reasoning that involves moving from a set of specific facts to a general conclusion. It can also be seen as a form of theory-building, in which specific facts are used to create a theory that explains relationships between the facts and allows prediction of future method of proof depends on it.[41]

This epistemology sets up for the main attack on Platonism (though not named) in Metaphysics Metaphysics is one of the principal works of Aristotle and the first major work of the branch of philosophy with the same name. The principal subject is "being qua being", or being understood as being. It examines what can be asserted about anything that exists just because of its existence and not because of any special qualities it has.[42] In brief, universal and particulars imply each other; one is logically prior or posterior to the other. If they are to be regarded as distinct, then they cannot be universal and particulars; that is, there is no reason to understand that universal from the objects supposed to be particulars. It is not the case that if a universal A might be supposed to have particulars a1, a2, etc., A is missing or a1, a2, etc. are missing. A does not exist at all and a1, a2, etc. are unrelated objects.

Dialogues that discuss Forms

The theory is presented in the following dialogues:[43]

Metaphor of the sun Plato, in The Republic , uses the sun as a metaphor for the source of "illumination", arguably intellectual illumination, which he held to be The Form of the Good, which is sometimes interpreted as Plato's notion of God. The metaphor is about the nature of ultimate reality and how we come to know it. Socrates is the speaker of The: The sun is to sight as Good is to understanding.
Allegory of the cave The Allegory of the Cave, also commonly known as Myth of the Cave, Metaphor of the Cave, The Cave Analogy, Plato's Cave or the Parable of the Cave, is an allegory used by the Greek philosopher Plato in his work The Republic to illustrate "our nature in its education and want of education". The allegory of the cave is written as a: The struggle to understand forms like men in cave guessing at shadows in firelight.

The term was used at least as early as Diogenes Laertius, who called it (Plato's) "Theory of Forms:" Πλάτων ἐν τῇ περὶ τῶν ἰδεῶν ὑπολήψει...., "Plato". Lives of Eminent Philosophers. Book III. pp. Paragraph 15.
  3. ^ Plato uses many different words for what is traditionally called form in English translations and idea in German and Latin translations (Cicero). These include idéa, morphē, eîdos, and parádeigma, but also génos, phýsis, and ousía. He also uses expressions such as to x auto, "the x itself" or kath' auto "in itself". See Christian Schäfer: Idee/Form/Gestalt/Wesen, in Platon-Lexikon, Darmstadt 2007, p. 157.
  4. ^ Forms (usually given a capital F) were properties or essences of things, treated as non-material abstract, but substantial, entities. They were eternal, changeless, supremely real, and independent of ordinary objects which had their being and properties by 'participating' in them. Plato's theory of forms (or ideas)
  5. ^ "Chapter 28: Form" of The Great Ideas: A Synopticon of Great Books of the Western World (Vol. II). Encyclopaedia Britannica (1952), p. 526-542. This source states that Form or Idea get capitalized according to this convention when they refer "to that which is separate from the characteristics of material things and from the ideas in our mind."

  8. ^ This transliteration and the translation tradition of German and Latin lead to the expression "theory of Ideas." The word is however not the English "idea," which is a mental concept only, and the famous theory has nothing at all to do with the "ideas" of English speakers. On the other hand, Plato's concept Form is as removed from the normal concept form as Idea is from idea.

  12. ^ For example, Parmenides 129: "Nor, again, if a person were to show that all is one by partaking of one, and at the same time many by partaking of many, would that be very astonishing. But if he were to show me that the absolute one was many, or the absolute many one, I should be truly amazed."
  13. ^ Cratylus 389: "For neither does every smith, although he may be making the same instrument for the same purpose, make them all of the same iron. The form must be the same, but the material may vary ...."
  14. ^ For example, Theaetetus 185: "... the mind, by a power of her own, contemplates the universals in all things."
  15. ^ The creation of the universe is the creation of time: "For there were no days and nights and months and years ... but when he (God) constructed the heaven he created them also." - Timaeus paragraph 37. For the creation God used "the pattern of the unchangeable", which is "that which is eternal." - paragraph 29. Therefore "eternal" - to aïdion, "the everlasting" - as applied to Form means atemporal.
  16. ^ Space answers to matter, the place-holder of form: "... and there is a third nature (besides Form and form), which is space (chōros), and is eternal (aei "always", certainly not atemporal), and admits not of destruction and provides a home for all created things ... we say of all existence that it must of necessity be in some place and occupy space ...." - Timaeus paragraph 52. Some readers will have long since remembered that in Aristotle time and space are accidental forms. Plato does not make this distinction and concerns himself mainly with essential form. In Plato, if time and space were admitted to be form, time would be atemporal and space aspatial.
  17. ^ These terms produced with the English prefix a- are not ancient. For the usage refer to "a- (2)". Online Etymology Dictionary. http://www.etymonline.com/index.php?term=a-. They are however customary terms of modern metaphysics; for example, see Beck, Martha C. (1999). Plato's Self-Corrective Development of the Concepts of Soul, Form and Immortality in Three Arguments of the Phaedo. Edwin Mellon Press. p. 148. ISBN 0773479503. and see Hawley, Dr. Katherine (2001). How Things Persist. Oxford: Clarendon Press. Chapter 1. ISBN 019924913X.
  18. ^ For example, Timaeus 28: "The work of the creator, whenever he looks to the unchangeable and fashions the form and nature of his work after an unchangeable pattern, must necessarily be made fair and perfect ...."
  19. ^ "No sensible man would insist that these things are as I have described them..." (Phd. 114d).
  20. ^ Paragraph 420.
  21. ^ The word is ethnos, "people". For the full range of meanings consult the American Heritage Dictionary online under ethnic.
  22. ^ Paragraph 399e line 5.
  23. ^ "Types" (genē) rather than the English economic classes or the favored populations of the real Greek cities.
  24. ^ Paragraph 424.
  25. ^ Paragraph 407.
  26. ^ Paragraph 410.
  27. ^ Paragraph 412.

  29. ^ Cratylus paragraph 440.
  30. ^ Aristotle in Metaphysics A.987a.29-b.14 and M1078b9-32 says that Plato devised the Forms to answer a weakness in the doctrine of Heraclitus, who held that nothing exists, but everything is in a state of flow. If nothing exists then nothing can be known. It is possible that Plato took the Socratic search for definitions and extrapolated it into a distinct metaphysical theory. Little is known of the historical Socrates' own views, but the theory of Forms is likely a Platonic innovation.
  31. ^ Cratylus paragraph 389.
  32. ^ Parmenides 131.
  33. ^ The name is at least as old as Aristotle, who says in Metaphysics A.IX.990b.15: "(The argument) they call the third man." A summary of the argument and the quote from Aristotle can be found in the venerable Grote, George (1880). "App I Aristotle's Objections to Plato's Theory". Aristotle: Second Edition with Additions. London: John Murray. pp. 559–60 note b. (downloadable Google Books). Grote points out that more likely than not Aristotle lifted this argument from the Parmenides of Plato; certainly, his words indicate the argument was already well-known under that name.
  34. ^ Analysis of the argument has been going on for quite a number of centuries now and some analyses are complex, technical and perhaps tedious for the general reader. Those who are interested in the more technical analyses can find more of a presentation in Hales, Steven D. (1991). "The Recurring Problem of the Third Man". Auslegung 17 (1): 67–80. http://www.bloomu.edu/departments/philosophy/pages/content/hales/articlepdf/thirdman.pdf. and Durham, Michael (1997). "Two Men and the Third Man". The Dualist: Undergraduate Journal of Philosophy (Stanford University) 4. http://www.stanford.edu/group/dualist/vol4/pdfs/durham.pdf.
  35. ^ Plato to a large extent identifies what today is called insight with recollection: "whenever on seeing one thing you conceived another whether like or unlike, there must surely have been an act of recollection?" - Phaedo paragraph 229. Thus geometric reasoning on the part of persons who know no geometry is not insight but is recollection. He does recognize insight: "... with a sudden flash there shines forth understanding about every problem ..." (with regard to "the course of scrutiny") - The Seventh Letter 344b. Unfortunately the hidden world can in no way be verified in this lifetime and its otherworldness can only be a matter of speculation Plato was aware of the problem: "How real existence is to be studied or discovered is, I suspect, beyond you and me." - Cratylus paragraph 439.

  39. ^ This distinction is made in Posterior Analytics paragraph 73a-b. In a nutshell, the Form of the essence of course is essential but in defining it any attribute that is necessarily said of it and is true in every instance is essential; otherwise, it is accidental; e.g., a line is essential to a triangle but its length is accidental. The triangle of course is an essence.
