What was platos theory of forms

An answer is too wide if, while it includes all cases of, for instance, piety, it also includes other things, cases of justice or impiety. He is seeking an answer which picks out a Socratic Property, e. Piety's power to make, e. Piety self-predicates: Piety is pious. In the Socratic dialogues Plato does not distinguish the metaphysical way in which Socrates is pious from the way in which Piety is pious—in these dialogues there appears to be just one ontological predication relation.

One has knowledge of a Socratic Property when she can give an account logos that says what X is, that is, when she can give the definition of the property under investigation.

Treating a definition as a linguistic item, we can say that the definition specifies or picks out the essence ousia of the property, and a definitional statement predicates the essence of the property whose essence it is.

It is unclear from the Socratic dialogues whether any other property is predicated of a Socratic Property: arguably Piety is pious and only pious. In contrast, the things that are pious, e. From what we can infer from Plato's remarks in these early dialogues, and from Aristotle's remarks, a Socratic property is in the sensibles—It is an immanent universal.

In this respect, the essence of Piety is also found in Socrates and thus the linguistic definition of Piety is also linguistically predicable of Socrates.

If Aristotle is right, Plato's problem with sensibles is that they change. The Phaedo is Plato's eulogy to Socrates.

It recounts the last hours of Plato's teacher. Towards that end we find a series of arguments whose aim is to prove the immortality of the soul. At least three of these arguments, the Argument from Recollection and its prelude 65aa and 72eb , the Affinity Argument 78bb , and the Final Argument aa and its prelude 95aa , are crucial for understanding Plato's initial thoughts on metaphysics and epistemology.

Here Plato draws a contrast between unchanging Forms and changing material particulars. Unfortunately, neither in the Phaedo nor in any other dialogue do we find Plato giving a detailed description of the nature of Forms, or particulars, or their interaction.

What is referred to as Plato's theory of Forms is thus a rational reconstruction of Plato's doctrine. In such a reconstruction scholars try to determine a set of principles or theses which, taken together, allow us to show why Plato says what he does about Forms, souls, and other metaphysical items.

In the attempt to make more precise what Plato is after, one risks attributing to Plato notions that are either not his or not as well developed in Plato as scholars would hope.

Perhaps the notion of a particular is such a case. Intuitively, particulars are things like my dog Ajax, Venus, my computer, and so on, the ordinary material things of the everyday spatio-temporal world. But we also speak of particular actions, particular events, particular souls, and much else. In a rational reconstruction, we can be more precise by stipulating, for instance, that a particular is that of which properties are predicated and which is never predicated of anything or anything other than itself.

In the author's opinion, the metaphysics of the Phaedo and other middle period works is devoted to developing the account of Forms; perhaps because while most of us think that included in what there is are the various, e. In the late dialogues, especially the Timaeus and Philebus , Plato attempts to give a systematic account of material particulars.

The argument of the Phaedo begins from Plato's assertion that the soul seeks freedom from the body so that it may best grasp truth, because the body hinders and distracts it: the soul comes to be separate choris from the body, itself by itself aute kath auten 64c5—8. The senses furnish no truth; those senses about the body are neither accurate nor clear. The soul reckons best when it is itself by itself, i. At this juncture, Socrates changes course:. This is the first passage in the dialogues widely agreed to introduce Forms.

First, Forms are marked as auto kath auto beings, beings that are what they are in virtue of themselves. In subsequent arguments we learn other features of these Forms. Then in the Affinity Argument we discover that Forms are simple or incomposite, of one form monoeidetic , whereas particulars are complex, divisible and of many forms. In the crucial Final Argument, Plato finally presents the hypothesis of Forms to explain coming into being and destruction, in general, i.

Once Cebes accepts the hypothesis, a novel implication is announced c3—7 :. In this passage, Plato introduces two predication relations, Being and Partaking.

At first blush, it seems that there are two kinds of subjects of which properties are predicated, namely Forms and material particulars. I exempt souls from this list. Similarly, at first blush it seems that there are Forms for every property involved in the changes afflicting material particulars. Helen of Troy, change from being not-beautiful to being beautiful, there is the Form Beauty Itself.

Generalizing from what is said here about Beauty Itself, it seems that Forms inherit from the Socratic Properties their self-predicational status: Beauty is beautiful; Justice is just; Equality is equal. Partaking in Beauty makes Helen beautiful because Beauty Itself is beautiful.

Understanding Being, the way in which Beauty is beautiful, that is, determining what it is for a Form to self-predicate, is central to understanding Plato's Theory of Forms and his middle period metaphysics. The debate over self-predication involves both statements and what the statements are about, i.

Thus at times it may be important to distinguish linguistic predication from ontological predication. One question then concerns the copula, or linking verb: in what manner is the predicate related to the subject, or how is the Form related to itself? There are three basic approaches to consider. In his seminal discussion of self-predication, Vlastos maintained that we should understand the relation between the Form and itself to be the same as that between a particular and the Form Vlastos d.

This is to say that Justice is just in the same was as Socrates is just, or that Beauty is beautiful in the same way as Helen is beautiful, or that the Circle Itself is circular in the same way as my basketball: both are round. Then Beauty is a beautiful thing, an item to be included in an inventory of beautiful things right along with Helen. Some scholars, e. According to the Approximationist, the Form is the perfect instance of the property it stands for. A particular that participates in the Form is an imperfect or deficient instance in that it has a property that approximates the perfect nature of the Form.

For instance, the Circle Itself is perfectly circular. A drawn circle, or a round ball, is deficient in that it is not perfectly circular, not exactly degrees in circumference.

If Beauty Itself is characterized by perfect beauty, then Helen has imperfect beauty and she does not have perfect beauty.

Since nothing rules out that there are numerous kinds of imperfect beauty, perhaps as many as there are beautiful participants, it seems either that there is no one kind of beauty that particulars have in common, or that there are one or more commonly shared imperfect kinds of beauty.

In the latter case, there is every reason to posit a Form s of Imperfect Beauty in which the commonly qualified imperfect particulars participate. Neither alternative is a happy one.

While the appeal to the perfection of the mathematical properties is great, even in these cases it is doubtful that Plato adopts an approximationist strategy see Nehamas b; c. An alternative is to allow that while both Beauty Itself and other items are characterized by beauty, Beauty Itself is simply and solely beautiful.

This characterizing variant emphasizes the Phaedo 's claims that a Form is monoeides and one Phaedo 78b4ff. Beauty is nothing but beautiful and thus is completely beautiful, differing from other beautiful things in that they are much else besides beautiful.

Helen is a woman and unfaithful and beautiful. According to the second approach see Cherniss a; Allen , self-predication statements assert identity between the Form and its essence. Indeed, typically backers of this approach exclude the possibility that a Form is characterized by the property it is, thus, e. The third approach, the Predicationalist see Nehamas c; Code ; Silverman , joins with the Identity approach in denying that self-predication statements signal that the Form is characterized by the property it constitutes.

And while ultimately it allows that a Form and its essence are identical, it does not regard the self-predication statement itself as an identity claim see Code ; Silverman Ch. Rather, a self-predication claim asserts that there is a special primitive kind of ontological relation between a Form subject and its essence predicate. This approach begins from the two relations of Partaking and Being introduced in the last argument of the Phaedo.

An intuitive first approximation of their respective functions is to treat Partaking as a relation between material particulars and Forms, the result of which is that the particular is characterized by the Form of which it partakes. So, Helen, by partaking of Beauty, is characterized by beauty; Helen, in virtue of partaking, is or, as we might say, becomes beautiful.

All particulars are characterized by the Forms in which each participates, and whatever each is, it is by partaking in the appropriate Form. On this account, then, there can be Forms for each and every property had by particulars Phaedo —, esp. In contrast to the characterizing relation of Partaking, the relation of Being is always non-characterizing. Each Form, F , is its essence ousia , which is to say that the relation of Being links the essence of beauty to the subject, Beauty Itself.

Put differently, whenever essence is predicated of something, the relation of Being is at work. Nor do I mean to suggest that everything else in the metaphysics can somehow be deduced from it. Rather, I mean to indicate that the relation of Being is not explained by appeal to another more basic relation or principle. Its nature, and the nature of other primitives in the theory, such as Participating, is displayed in the ways in which the theory attempts to save various phenomena. Throughout the dialogues, Forms are said to be one, hen , or monoeides.

See especially the Affinity Argument in the Phaedo , 78bb. These passages suggest that the self-predicational nature of Forms implies that the only property predicable of a Form is itself: i.

But other passages suggest that Forms cannot be simple in this strict sense. From the Republic we know that all Forms are related to the Good. While it is difficult to be certain, Plato seems committed to the claim that each Form is good, that is, that each Form is a good thing or is characterized by goodness.

More doubts about the strict simplicity of Forms emerge from reflection on the nature of definition in Plato's middle period. Ontologically, all definitions predicate the essence of the Form whose essence it is. Plato is attempting to discover through scientific investigation, or inclusive or through an analysis of what words mean, or through any other method, what the nature of, say, Justice is—compare the ways in which philosophers and scientists work to discover what, e.

According to this line of reasoning, the self-predication statements in the texts are promissory notes, shorthand for what will turn out to be the fully articulated definition. Plato is thus committed to there being Forms whose nature or essence will ultimately be discovered.

The problem is that the fully articulated linguistic definition, when it is ultimately discovered, will turn out to be complex. For instance, Heat, one thing, is mean molecular kinetic energy, a seemingly complex notion. So in Plato we find Republic, d that Justice is Doing One's Own, that a Name is Cratylus, b a tool that is informative and separates nature, or, though Plato never says it, that Human is rational bipedal animal.

Since philosophical and scientific progress is supposed to teach not that Justice is just but what Justice is, at some level at least Forms cannot be considered to be utterly and strictly simple. The problem is that given just two predication relations, it is unclear whether Plato thinks that Forms partake of the properties to which they are related or whether they are those properties. The best guide to the separation of Forms is the claim that each Form is what it is in its own right, each is an auto kath auto being.

What each Form is, what each Form is in its own right, it is in virtue of its essence, ousia. The connection between the Form and the essence being predicated of it is exhibited in the Republic 's formula that a given on being is completely or perfectly ff , as well as the so-called self-predication statements. According to the predicationalist reading, the relation connecting an essence with that Form of which it is the essence is Being see Code , esp.

II captures the ontological force of the expression that each Form is monoeides : of one essence. In light of these principles, and in keeping with the account of the ontological relation of Being, it follows that each Form self-predicates, in so far as each Form Is its essence. Self-predication statements are thus required of Forms, since every Form must Be its respective essence. Self-predication, then, is a constitutional principle of the very theory of Forms.

In virtue of Being its essence, each Form Is something regardless of whether any particular does or even may participate in it. Thus each Form is separate from every particular instance of it. Moreover, since its essence is predicated of the Form independently from our knowledge of the Form or from its relation to another Form, a Form is not dependent on anything else.

On this definitional interpretation of separation, an item is separate just in case the definition essence is predicable of it and not of what it is alleged to be separate from. Whether or not a Form is existentially separate, i. To the extent that Plato recognizes the notion of existence, since being an essence seems, by Plato's lights, to be the superlative way to be, it is likely that Forms are both definitionally and existentially separate. The middle period dialogues contain few arguments whose conclusion is that such and such a Form therefore exists.

These include the moral properties familiar from Socrates' ethical inquiries and properties such as Beauty, Equality, Hot and Cold, or Largeness. There is no precise way to specify what counts as an incomplete property. Roughly, the idea is that an incomplete property is one which, when serving as a predicate, yields a statement that cannot be understood on its own, because they must be added on to, or completed in some sense, typically with a prepositional phrase. For some readers, then, while the Plato of the middle period may believe in a wide range of properties, he is theoretically committed only to a limited number or range of Forms, namely Forms of incomplete properties.

Forms are limited to these incomplete properties because, on this line of reasoning, these properties present special problems when they are instantiated in particulars. This is the phenomenon where, with respect to any incomplete property, F , every sensible particular that is F is, in some sense, also not- F. So, if Elsie the cow is large, she is also not-large; for Elsie is large in comparison to her calf but not-large in comparison to Elmer the bull. Thus Elsie is large and not-large.

Since, according to this approach, Plato is seeking a large that is the unqualified bearer of largeness, and since every particular is disqualified in light of compresence, Plato postulates a Form, Largeness Itself, to be the unqualified bearer.

By way of contrast, properties such as being brown or being a cow do not suffer compresence when instantiated by particulars. That is, Elsie is a cow and is not not-a-cow; she is brown imagine she is brown all over and is not not-brown.

In the modern parlance, being a cow is classified as an essential property of Elsie whereas being brown is an accidental property. Thus the proponent of Forms only for incomplete properties looks to a special subset of the accidental properties, namely those where there is no unqualified possessor.

In order to appreciate fully the rationale for this account, one needs to consider Plato's account of particulars, for the compresence of opposites is meant to capture in what sense particulars are deficient with respect to Forms. Rather, we are told that the key notion is being completely. So, just as Elsie is completely a cow, so Largeness is completely large: Largeness is a complete bearer of an incomplete property.

Metaphors dominate Plato's remarks about the relation of particulars to Forms. Of special importance are the metaphors of image and original, copy and model, example and paradigm. The physical world and all of its constituents are, according to Plato, a copy or image of the Forms, and since all copies are dependent on the original, the physical world is dependent on Forms. In so far as Platonic Forms are not dependent on particulars, i.

A second important metaphor from the Phaedo also suggests that particulars are dependent on Forms whereas Forms are not dependent on them. Particulars strive to be such as the Forms are and thus in comparison to Forms are imperfect or deficient.

Forms, then, are independent, whereas particulars are dependent on Forms and thus deficient with respect to them. The Phaedo especially the Affinity Argument, 78bb also points up a host of features, usually found in pairs, which differentiate particulars from Forms. Forms are immaterial, non-spatial and atemporal. Particulars are material and extended in space and in time.

Forms do not change and may not even be subject to Cambridge-change, i. Particulars change, may even be subject to change in any respect, and may even be subject to change in every respect at any given moment , i. Particulars are complex or multi-form polyeidetic composites suntheton , whereas Forms are pure, simple or uniform monoeidetic, hen. Particulars are the objects of the senses and of belief. Forms are the objects of knowledge, grasped by the intellect through definitions, dialectic, or otherwise.

Particulars appear, and perhaps are, both F and not- F for some property F : particulars suffer from the compresence of opposites. The Form of F cannot be conceived to be not- F and perhaps is never not- F. Aristotle's account of Plato's reasons for introducing Forms indicates that change and essence are critical to Plato's thinking about the deficiency of material particulars.

Plato, accepting this, thought that this defining comes to be about different things, and not about sensibles. For it is impossible that the common definition be about any of the sensibles, for these are always changing. The question is where one can find definitions or definables. Aristotle asserts that Plato thought that definitions could not be found in the sensibles because they were always changing.

Following Aristotle's lead, a most economical way to account for the cognitive superiority of Forms and the inferiority of sensibles would be to allot essences only to the Forms.

Since we know from the early and the middle dialogues that knowledge is of essence, it is tempting to think that the absence of essence is responsible for the deficiency of the particulars.

Particulars are deficient because they can or do change. They change because their properties are contingent. Their properties are contingent because they lack any essences or any essential properties. But this is too quick. First, Plato's particulars may not change with respect to all of their properties. Perhaps some have essential properties along with a host of contingent properties. Then Aristotle might be taken to imply that only with respect to a certain number of contingent properties did Plato posit definable Forms.

Moreover, Aristotle seems to allude only to an epistemological difficulty arising from changing particulars. It is possible that this difficulty arises independently of whether some particulars have essential properties.

For instance, particulars might be epistemologically problematic because they have many properties, only some of which are changing. Certain passages e. Suppose that a particular is F. Complexity entails that a particular has at least two properties, F and G. Since the G is not- F , every complex particular can be said to be F and not- F. Our inability to grasp the property F in the particular is then grounded not in the compresence of an opposite property, but in the compresence of another property.

The inquiring mind is unable to isolate the desired property from any other. This suggests that a fundamental contrast between the particulars and the Form F is that the latter is simple, or monoeidetic, in that it possesses just itself—It is just F. If we emphasize the contingency of all of its properties, a particular cannot have any essential properties. On the other hand, if we emphasize the complexity of the particular, then we are free to ascribe essences to some particulars.

Hence, there could be knowledge of these particulars, i. Conversely, if complexity is the cause of cognitive deficiency, then with respect to Forms, the fact that all their properties are necessary properties would not suffice to render Forms knowable. Thus Forms, too, might not be knowable. There is reason to doubt that the compresence of opposites or the mere complexity of particulars is responsible for their deficiency but see Fine , esp.

According to Aristotle, change is critical, especially in so far as it precludes definability and thus knowledge. Given that knowledge requires essence, and essence excludes change in the case of the essential properties , Aristotle would have us deny that essence is predicable of particulars for the Plato of the middle period.

Particulars will be epistemologically deficient in that there can be no knowledge of them, unless we abandon the thesis that knowledge is of essence. And particulars will be metaphysically deficient, at least to the extent that possessing an essence is a better state than lacking one. But more can be said about the peculiar contingent manner in which particulars have their properties and why it is that one cannot look to the particular beauties to obtain knowledge of, e. From the outset of the Phaedo, particulars are branded as material and, as a result, spoken of in the pejorative.

Indeed, matter seems to be at the root of the other features that characterize particulars. What is extended in space and through, or in, time is body. The composite is also linked with the material. Because a material particular is composite, it is also multi-form or complex Phaedo 80b4. Complex material particulars are subject to change in so far as their composite nature invites dissolution or construction, or more generally coming-to-be or perishing.

And since compresence requires complexity, the material nature of particulars is one of the roots of each material, sensible particular being both F and not- F. The spatio-temporal, material character of particulars also contributes directly to the explanation of their suffering, and seeming to suffer, the compresence of opposites.

In the middle period, Plato seems to accept an account of perception that has as a necessary component the interaction of material elements. The qualifications needed to account for a particular's being F and not- F are temporal, or a function of being comparable to other extended material objects, or standing in different relations to perceivers.

In virtue of their material nature, particulars are extended, mutable, and subject to generation and destruction. How then is the materiality of the particular related to the characterization for which participation is responsible? What materiality induces is that a property be manifested in a specific way. So, when we consider a particular stick to ask what is its length, we expect to be told a specific quantity: the stick is five inches long.

The same is true of its weight: it is six ounces. If we are concerned to explain why the stick is that long, one answer is that the matter of the particular compels it to have determinate length. In the Meno 74ff , Plato develops the notion of determinable and determinate.

There the properties themselves are determinates falling under a determinable, e. Remember plato was alive a very long time ago when he came up with these ideas, if he can COME UP with this stuff, im sure all of us today can at the very least comprehend it. My mom has dementia. I think she is describing forms. She describes actually seeing them be absorbed.

My comprehension of form is like Plato's except from my perspective all forms are perfect for an intended purpose. No two manifestations are exactly alike but are alike in a general way. That is because every life-force has to, by reincarnating, experience all of those variances in order to become the fulfillment of them all. The purpose of earth's plane.

Not only do life-forces incarnate as human but as every type of manifestation earth is composed of to include eventually being earth's life-force. Not only is that true concerning earth but every type of manifestation in the "Zeroverse" most human call universe. Eventually every life-force within existence becomes the life-force forming the zeroverse or existence as the one true form.

That is the same as is said in the Christian religion, "I am in the father and the father is in me. Marine Biology. Electrical Engineering. Computer Science. Medical Science. Writing Tutorials. Performing Arts. Visual Arts. Student Life. Vocational Training. Standardized Tests. Online Learning. Social Sciences. Legal Studies. If the intelligent souls who do not degrade must live in harmony with the Theory of Forms then they must aspire to the perfect state as set out by Plato this is for another essay.

The state would attempt to reach the ideal forms of each notion such as the Good, the Truth, property, and so on. This takes us back to the unseen notions discussed above. If a notion has an ideal then it would apply indiscriminately to all people. There would be no relativity. However, if the state is designed for the common good then the notion also follows the common good or the good of the many over the good of the few.

Plato believed that the only people who could administer such a state were the philosophers; especially his ideal philosopher king class. This would prevent the degradation of the state and the degradation of knowledge into opinion. There were extreme consequences for anyone who might fall into opinion and away from the ideals — death.

He was trying to solve one of the great questions in philosophy known as the Problem of Universals. What is the Problem of Universals? The problem of universals relates to the properties of things objects and notions.

Do these properties exist and if so, what are they? As with the Theory of Forms, we have to go back to Thales for the problem of universals. He posited the following universal theory:. All triangles inscribed within a circle are right triangles. This prompts the following questions:. How do we know this is a universal theorem? What is a right triangle? Are all right triangles right triangles? What is a triangle? What is a circle? So our universals are that:. All triangles have three sides and three angles.

All right triangles have a 90 degree angle. All circles are perfectly round. So we have applied some logic and defined our terms, but how do we know they are all universals?

This comes to the age old question which divides Plato from Aristotle. Does the concept inform what we see or does what we see inform the concept?

But we can also go further — even if we can see infinite triangles inscribed within circles and that they are all right triangles, does it make it universal? Not only that, but to be a universal form it has to be unchanging and eternal. My thoughts: There are universal properties. The question is how is it provable that a universal property is indeed universal and unchanging or in fact a sound property. A key element to universals is the idea of concept formation.

Right back at the beginning of this article I used the example of a toddler learning what a table is. How does the toddler end up with the table concept?

The Platonic Theory of Forms dictates that the child came with the theory pre-programmed. This means, according to Plato, the universal idea of a table existed before humans had table approximations. In theory that means a prehistoric human hunter-gatherer in the savannah had the ideal form of the table within their mind even though there were no tables.

Someone wanting to do architecture, for example, would be required to recall knowledge of the Forms of Building, House, Brick, Tension, etc. The fact that this person may have absolutely no idea about building design is irrelevant. Not everyone is suited to be king in the same way as not everyone is suited to mathematics.

Conversely, a very high standard in a particular trade suggests knowledge of its Forms. The majority of people cannot be educated about the nature of the Forms because the Forms cannot be discovered through education, only recalled. To explain our relationship to the world of the Forms, in the Republic Plato uses the analogy of people who spend their whole lives living in a cave [see Allegory of the Cave ]. All they ever see are shadows on the walls created by their campfire.

Compared with the reality of the world of the Forms, real physical objects and events are analogous to being only shadows. Plato also takes the opportunity to use the cave analogy as a political statement. Only the people who have the ability to step out into the sunlight and see recall the true reality the Forms should rule.

Clearly Plato was not a fan of Greek democracy. No doubt his aristocratic background and the whims of Athenian politics contributed to his view, especially as the people voted to execute his mentor Socrates. Plato leaves no doubt that only special people are fit to rule.
