>>24554825 (OP)Many philosophical terms and concepts we use today, even outside of philosophy, have their roots in Aristotle's work. Concepts like "substance," "potentiality and actuality," "cause," "teleology" (purpose/end), and categories of being are all deeply embedded in our intellectual vocabulary.
Aristotle is widely considered the father of formal logic, particularly syllogistic logic. His work in the Organon laid down the principles of valid reasoning, deduction, and argument structure. While modern logic has advanced far beyond his initial formulations (e.g., symbolic logic), his foundational work was revolutionary and remains a starting point for understanding the history of logic.
Aristotle called metaphysics "first philosophy" – the study of "being as being," exploring the fundamental nature of reality, existence, and the ultimate causes of things.
