The ideas introduced by Plato on the theory of forms, where deducted and critiqued by Aristotle. Both philosophers can be viewed as having opposing ideologies. Nonetheless, Plato and Aristotle are in agreement on certain factors of their philosophy.
Many have scrutinized and compared the dissimilarities and similarities of Aristotle's doctrine of categories and Plato's theory of forms. The observations found are of an interesting nature.
The beauty behind the writings of Plato is to not accept what is interpreted through the senses. In Plato's theory of forms, Plato explained the immaterial world as the realm containing the perfect form of objects and ideas that are presented on Earth. For instance, the idea of justice is inadequate on Earth, but in an alternate universe the idea of justice is in its perfect form.
When comparing living things, Plato would describe the object he viewed in the physical world as an idea or an imperfect form of the object he studied. If Plato were to observe a tree in the physical realm he would add “ness” to an object to make it known that the tree he saw before him was participating in the form of a tree, and is merely an outline of an ideal tree.
Aristotle disagreed with Plato’s ideology of an immaterial world and an invisible world not seen by the human eye. The system of Aristotle’s logical explanations against Plato’s theory of forms, were made through observations of the physical world. Aristotle unlike Plato trusted the senses as a tool to judge reality. He found Plato’s theory of forms defective, for he thought true reality contained concrete objects that one perceived through the senses. To oppose Plato’s theory, Aristotle created his doctrine of categories.
The doctrine of categories explained that an object contains certain groups that define that particular object, whether it be quality, quantity, relation or substance. Aristotle considered every characteristic examined in a particular object as a distinction that defined that specific entity. Aristotle believed that the substance of a particular living thing (such as a bird) indicates a true independent existence. The other qualities of a living thing such as height and color are imitative traits of being in that they are present only to an individual substance.
As Aristotle studied an object he would use the word “this” to describe that he was observing a particular object. When examining an animal like a horse, he would bear in mind that the horse was independent of other horses due to certain physical characteristics that separated that individual horse from other horses. The natural scientist and philosopher, Aristotle opposed Plato’s perspective of not considering characteristics that an object contained which created an individual identity of that specific object.
Plato’s concept of an alternate universe, containing perfect forms of objects was in Aristotle’s view a foolish assumption. Aristotle believed that there was a point in...
