Metaphysics is Aristotle's version of philosophy examining the nature of reality, including the relationship between mind and matter, substance and attribute, fact and value. Aristotle argues that there are a handful of universal truths. Aristotle's works have influenced science, religion, and philosophy for nearly two thousand years. He could be thought of as the father of logical thought. Aristotle wrote: "There is nothing in the intellect that was not first in the senses." He wrote that everything that is learned in life is learned through sensory perception. Aristotle was the first to establish the founding principle of logic. The great writer Dante called Aristotle "The Master of those who know."
