Aristotelian logic is a system of reasoning developed by the ancient Greek philosopher Aristotle. It focuses on syllogisms, which are logical arguments that consist of two premises leading to a conclusion. For example, if all humans are mortal and Socrates is a human, then Socrates is mortal. This form of logic emphasizes the structure of arguments and the relationships between different statements. Aristotelian logic is foundational to the study of logic and has influenced various fields, including philosophy, mathematics, and computer science. It provides a framework for evaluating the validity of arguments and understanding how conclusions can be drawn from given premises.
