What is the difference between platos and aristotles view of the forms
Once those facts have been accounted for, there is no need to look for the same explanations of the theoretical entities which have been introduced to provide the original explanation.
This way out of the regress involves denying that forms have essences, i. This position faces a number of textual obstacles. Their essences are not some further thing, distinct from them. The difficulty with this is that it is not clear that the defender of 3 can claim that forms have definitions of any sort and still maintain a doctrine that is distinct from both 2 , on the one hand, and 4 on the other.
Given that forms are definitions, they must have a structure that approximates to that of a linguistic entity. Whatever else one says about them then, it seems clear that they must be divisible in thought into component parts, as complex predicates are divisible into words. We may ask of these component parts whether or not they are matter-involving, i.
It might seem as though it does not make much difference whether Aristotle subscribes to position 1 or 2. According to 2 , every physical object has two forms associated with it: a matter-involving one, which combines with the proximate matter to make up the compound, and a second form or essence of this matter-involving form, which is not matter-involving. However, the defender of pure forms must admit that there is also a broader definition of a thing, which does include its matter, as well as its other causes.
For example, the essence or form of a human being is a soul. A commitment to two essences or forms per compound substance is an additional metaphysical commitment in a way that a broader linguistic definition of a thing that mentions both its form and its matter need not be.
If important theoretical work cannot be found for matter-involving forms, then, pure forms are the more ontologically parsimonious choice. Although introduced as contrastive notions suited to explicate change and substantial generation in the absence of generation ex nihilo , any easy contrast between form and matter turns out to be difficult to sustain once it finds employment in its further applications. Even so, as Aristotle implies, and as many of his followers have affirmed, hylomorphism proves no less elastic than explanatorily powerful across a wide range of explanatory roles.
Form vs. Matter and form introduced 2. Prime matter 3. The principle of individuation 4. Matter and form introduced Aristotle introduces his notions of matter and form in the first book of his Physics , his work on natural science. Prime matter One obvious question pertains to how low such underlying levels might go. In Metaphysics ix 7, he uses a conditional to talk about the possibility: it seems that what we call not this, but that-en—for example, we call the box not wood, but wooden, nor do we call the wood earth, but earthen, and again earth, if it is this way, we do not call something else, but that-en—that is always potentially without qualification the next thing…But if there is something primary, which is no longer called that-en with respect to something else, this is prime matter.
Put schematically, the argument looks like this: It is possible that Socrates and Callias be composed of numerically the same matter albeit at different times. Socrates and Callias have the same form. Socrates and Callias are compounds of matter and form.
Therefore, it is possible that Socrates and Callias are numerically the same. Matter-involving forms As we have seen, Aristotle introduces matter and form as contrasting notions, distinct causes, which together make up every ordinary object. The chapter goes on to describe how some people are in doubt even in the case of the circle and the triangle, on the grounds that it is not right to define them in terms of lines and continuity, but that these too should all be spoken of in the same way as flesh and bones of man and bronze and stone of statue.
With this in mind, we can divide the possible views about matter-involving forms into the following four positions, with ascending degrees of matter-involvement: Pure forms: natural compounds and their forms have forms or essences that are not matter-involving.
Compounds have forms or essences that involve matter, i. As in 2 , compounds have forms or essences that involve matter; but forms themselves have no essences or forms.
As in 2 and 3 , compounds have forms or essences that involve matter; and so do forms, i. Bibliography Primary Sources Apostle, H. Barnes, J. Bostock, D. Charlton, W. Hamlyn, D.

For centuries, classical education assigned Plato's works as required reading, and The Republic was the premier work on political theory until the 19th century, admired not only for its views, but also for its elegant prose.
Aristotle and his works became the basis for the both religion and science, especially through the Middle Ages. In religion, Aristotelian ethics were the basis for St. Thomas Aquinas ' works that forged Christian thought on free will and the role of virtue. Aristotle's scientific observations were considered the last word in knowledge until about the 16th century, when Renaissance thought challenged and eventually replaced much of it.
Even so, Aristotle's empirical approach based on observation, hypothesis and direct experience experimentation is at least part of the basis for scientific activity in nearly every field of study. He is said to have written almost treatises on an array of subjects, but only 31 have survived. Some of his other works are referenced or alluded to by contemporary scholars, but the original material is gone.
What remains of Aristotle's works are primarily lecture notes and teaching aids, draft-level material that lacks the polish of "finished" publications. Even so, these works influenced philosophy, ethics , biology, physics, astronomy, medicine, politics, and religion for many centuries. His most important works, copied hundreds of times by hand throughout ancient and medieval times, were titled: Physics ; De Anima On the Soul ; Metaphysics ; Politics ; and Poetics.
These and several other treatises were collected in what was called the Corpus Aristotelicum and often served as the basis for hundreds of private and teaching libraries up to the 19th century. Plato's works can be roughly divided into three periods.
His early period featured much of what is known about Socrates, with Plato taking the role of the dutiful student who keeps his tutor's ideas alive. Most of these works are written in the form of dialogues, using the Socratic Method asking questions to explore concepts and knowledge as the basis for teaching.
Plato's The Apology , where he discusses the trial of execution and his teacher, is included in this period. Plato's second or middle period is comprised of works where he explores morality and virtue in individuals and society. He presents lengthy discussions on justice, wisdom, courage, as well as the duality of power and responsibility.
Plato's most famous work, The Republic , which was his vision of a utopian society, was written during this period. The third period of Plato's writings mainly discusses the role of arts, along with morality and ethics.
Plato challenges himself and his ideas in this period , exploring his own conclusions with self-debate. The end result is his philosophy of idealism, wherein the truest essence of things occurs in thought, not reality. In The Theory of Forms and other works, Plato states that only ideas are constant, that the world perceived by senses is deceptive and changeable. Plato believed that concepts had a universal form, an ideal form, which leads to his idealistic philosophy. Aristotle believed that universal forms were not necessarily attached to each object or concept, and that each instance of an object or a concept had to be analyzed on its own.
This viewpoint leads to Aristotelian Empiricism. For Plato, thought experiments and reasoning would be enough to "prove" a concept or establish the qualities of an object, but Aristotle dismissed this in favor of direct observation and experience. In logic, Plato was more inclined to use inductive reasoning , whereas Aristotle used deductive reasoning. Both Aristotle and Plato believed thoughts were superior to the senses. However, whereas Plato believed the senses could fool a person, Aristotle stated that the senses were needed in order to properly determine reality.
An example of this difference is the allegory of the cave , created by Plato. In Book I of Politics, Aristotle describes how the state came into being and makes the claim that all states are natural. He reaches this conclusion by examining essential human relationships in their simplest form. In the human world, there is a natural pairing of those dependent on one another for survival, two such relationships are the master-slave and male-female pairings.
The female is paired with the male for the sake of reproduction, the survival of the human race Politics, pg. The master-slave relationship is one of preservation because they complete one another. Nature creates for each separate thing a separate end, because an object is most effective at its task when it serves a single purpose. The natural end for a master is to rule, and the natural end for the slave is to be ruled, therefore, unless the two are paired together they will individually be forced to perform tasks that they are not created for and thus will not be acting in accordance with nature Politics, pg.
A household is the first association that arises from the combination of the male-female and master-slave pairing.
The household, or family, comes into being for the sake of satisfying daily recurrent needs. The next stage of human association is the village, which in its most natural form arises when the relatives of the original household form their own households in the same geographical region and thus a natural combination of households, or a village arises.
The village comes into being in order to move towards a greater degree of self-sufficiency and the satisfaction of more than daily recurrent needs. The final association is the polis or state, which is entirely self-sufficient, and is created from a combination of villages.
The state is the final and perfect form of association because it accomplishes complete self-sufficiency, which is the object of all human associations, and helps human beings reach the object of their existence, which is happiness.
Every state exists by nature because they are the completion of associations arising from essential human pairings Politics pg. Plato reaches his conclusion by first explaining what characteristics an ideal city would have. Plato states first that the polis comes into being because no person is completely self-sufficient Republic, b.
An ideal state, he reasons will exist when each person does only what he is naturally suited for in order to guarantee the best quality work Republic, c. The object of the ideal state is for the city as a whole to be as happy as nature allows, which is accomplished through specialization Republic, c. After explaining the various specifics of the different specialized levels of labor needed for the ideal city, including the producing class and a class of guardians, he concludes that this ideal city centered on strict specialization based on natural talent is completely good Republic, e.
Once the city is completely good, he reasons it must contain the four virtues of wisdom, moderation, courage, and justice Republic, e. Wisdom in the ideal city is located in the ruling class, which are true guardians who possess a form of knowledge called wisdom Republic, e. Courage is located in the guardian class, and is defined as the preservation of the belief of what things are to be feared as defined by law and education Republic, d.
Despite his criticisms though, Aristotle was influenced by Plato, making their works, which target the same aspects of philosophy, easily comparable. These points led to a sceptic point of view which both philosophers wished to target, as both agreed knowledge is possible. In order to overcome this prevalent contradiction in the argument, it became necessary that each philosopher choose a point to disregard and prove to be unnecessary. Plato chose to reject the claim that the world experienced through the senses is what is real, while Aristotle rejected the claim that knowledge must be of what is fixed and unchanging.
This presented problems to be overcome by each philosopher: Plato had to give an account of where knowledge could be found while Aristotle had to account for how to have knowledge of that which is undergoing change. Plato and Aristotle both used their definitions of "form" to overcome their relative problems when it came to knowledge.
Form for both philosophers was able to classify all things: chairs are chairs because they reflect the form of a chair. However, their precise definitions of form did differ. Plato claimed that Particulars objects are only crude representations of their Form. For example, a Beauty Particular such as Helen of Troy is physical and accessible to the senses.
Her beauty is also only temporary and relative to the observer, because aging and individual opinions alter how her beauty is observed. Her beauty being combined with non-beautiful parts and non-beautiful perspectives, such as organs, mean that she cannot contain the permanent Form of Beauty within herself.
Rather, Plato claimed that the Form of Beauty is not accessible to the senses and is not physical, existing outside of time and space, and so can only be understood through reason. The Form of Beauty being pure beauty also differs from the Beauty Particular as it is eternally and irrefutably beautiful no matter who experiences it and at what time.
So, a chair is a chair because it has been designed to have the function of a chair. That of which the chair is made could have been given a different form if it had been arranged differently.
This way, the form of an object exists within the object and all similarly designed and purposed objects, so it is unnecessary to disengage from this world in order to understand a form as it can be observed and understood on earth.
This also enables one to have knowledge of an object whilst it undergoes change, as its change is contained within its purpose.
