His work in metaphysics had a significant impact on the topic

A subfield of philosophy known as metaphysics is concerned with the fundamental nature of reality, encompassing ideas like being, knowing, identity, time, and space. The term is derived from a later collection of Aristotle's writings known as Metaphysics. Aristotle addresses the impersonal characteristics of life itself, as well as general laws of being, in his book Metaphysics. He refutes Plato's Theory of Forms, which held that everything in the universe was an imperfect expression of an ideal form, and advances his claims on universal laws, amorphous concepts, and life itself. It primarily aims to gain wisdom.

Aristotle contends that information may be channeled scientifically to achieve wisdom rather than relying solely on the senses. Understanding the underlying principles of the universe and how it operates is the only way to get wisdom. The epic, or at least what is now available, covers 14 novels. Each volume focuses on a different subject, such as introductions, the rule of contradictions, and teleological explanations. His hypothesis of changing substances is one of them, and it may be the most contradictory. He categorizes substances into three groups, with the Unmoved Mover serving as an example of the purest sort. He compares it to God and ascribes to it conflicting assertions like being the cause of everything while being impartial.

This notion was deemed lyrical by Aristotle, who instead based his metaphysical inferences on empiricism and science. The nature of existence, how objects exist in the natural world while changing, and how this world may be comprehended are Aristotle's main concerns in Metaphysics. Considered to be among the best philosophical writings is The Metaphysics. It not only had a significant impact on western culture for centuries, but it also had a significant impact on Muslim intellectuals of the Middle Ages.
