Abstract

Grasp principles and create concepts seem to be very close activities in Aristotle’s epistemology. Indeed, definitions are among Aristotle’s principles of science. They are not as universal as logical principles, but they are indispensable for the very existence of science, which is a kind of knowledge that must involve truth and truth exists only in language. Nevertheless, as elements of language, definitions and concepts are created under the structure of words, and these represent objects not in a natural way but by convention. Though the philosopher does not state it, a concept/noema – despite being a product of intelligence/noesis – is always a product of a specific culture and, consequently, is science. From this point of view, science would be a kind knowledge that intends to be universal, but it is no more than an interpretation which is culturally limited by a language.
