It is very difficult to define the philosophy. The root of philosophy is the Greek word meaning “love of wisdom”. Some thinkers have defined philosophy as follows: Philosophy is the attempt to understand the fundamental and all-encompassing world by its perceptual powers and on the basis of objective reality. On this basis, we can call philosophy “deep thought on important and fundamental issues”. Aristotle, in metaphysics, also considers the search for knowledge to be characteristic of all human beings, and begins Chapter I of Book I (The Great Alpha) as follows: “All human beings in their nature seek knowledge”.
