Plato

Aristotle refutes Plato's Theory of Ideas on three basic grounds: that the existence of Ideas contradicts itself by denying the possibility of negations; that his illustrations of Ideas are merely empty metaphors; and that they theory uses impermanent abstractions to create examples of perception. Though the theory is meant to establish concrete standards for the knowledge of reality, Aristotle considers it fraught with inconsistencies and believes that the concept of reality depends upon all forms' correlations to other elements. Ideas, Plato believes, are permanent, self-contained absolutes, which answered to each item of exact knowledge attained through human thought. Also, Ideas are in Plato's view concrete standards by which all human endeavor can be judged, for the hierarchy of all ideas leads to the highest absolute - that of Good. In addition, the theory claims that states of being are contingent upon the mingling of various Forms of existence, that knowledge is objective and thus clearly more real, and that only the processes of nature were valid entities. However, Aristotle attacks this theory on the grounds that Plato's arguments are inconclusive either his assertions are not al all cogent. Aristotle says, or his arguments l

nts lead to contradictory conclusions. For example, Aristotle claims that Plato's arguments lead one to conclude that entities (such as anything man-made) and negations of concrete ideas could exist - such as "non-good" in opposition to good. This contradicts Plato's own belief that only natural objects could serve as standards of knowledge. Also, Aristotle refutes Plato's belief that Ideas are perfect entities unto themselves, independent of subjective human experience. Ideas, Aristotle claims, are not abstractions on a proverbial pedestal but mere duplicates of things witnessed in ordinary daily life. The Ideas of things, he says, are not inherent to the objects in particular but created separately and placed apart from the objects themselves. Thus, Aristotle says, Plato's idea that Ideas are perfect entities, intangible to subjective human experience, is meaningless, for all standards are based somewhere in ordinary human activity and perception. Thirdly, Aristotle assails Plato's efforts to find something common to several similar objects at once, a perfect exemplar of the quality those things share. Beauty is a perfect example; Plato considered Beauty both a notion and an ideal, isolated by abstractions and fixed permanently while its representatives fade away. Aristotle claims that abstractions like Beauty cannot be cast as absolutes, independent of temporal human experience; the Idea of Beauty changes with time and individual perceptions and cannot (as Plato felt) exist forever as a concrete standard. Plato and Aristotle reach some agreement, though, on the topic of reality. Plato believes that all reality was derived from his Ideas (which themselves dealt with concrete hierarchy of rati!

onal ideas. St. Anselm, though, makes the most dogmatic and logically tortuous case for God's existence, relying not upon explanations of goodness, truth, or rational order of ideas but upon an absurd argument. He claims that everyone has some sense of God, a
