2000年3月18日 · Aristotle’s logic, especially his theory of the syllogism, has had an unparalleled influence on the history of Western thought. It did not always hold this position: in the Hellenistic period, Stoic logic, and in particular the work of Chrysippus, took pride of place.

Aristotle distinguishes between what I will call, for convenience, rigorous logic and persuasive logic. Rigorous logic aims at epist ē mē , true belief about what is eternal, necessary, universal, and unchanging.

In logic and formal semantics, term logic, also known as traditional logic, syllogistic logic or Aristotelian logic, is a loose name for an approach to formal logic that began with Aristotle and was developed further in ancient history mostly by his followers, the Peripatetics. It was revived after the third century CE by Porphyry 's Isagoge.

This article concludes with a discussion of the syllogism and of the distinction between perfect and imperfect deductions.

Aristotle’s logical writings comprise six works, known collectively as the Organon (“Tool”). The significance of the name is that logic, for Aristotle, was not one of the theoretical sciences. These were physics, mathematics, and metaphysics. Instead, logic was a tool used by all the sciences.

For Aristotle, then, logic is the instrument (the "organon") by means of which we come to know anything. He proposed as formal rules for correct reasoning the basic principles of the categorical logic that was universally accepted by Western philosophers until the nineteenth century.

2023年10月30日 · Aristotle saw logic as the key to uncovering the causes and principles behind natural phenomena, human behavior, and even moral decisions. By applying logical methods like syllogisms and deduction, philosophers and scientists could better understand the nature of reality and how things work.

2023年10月7日 · Aristotle (384–322 BCE) is often regarded as the father of logic due to his systematic approach to reasoning. His influence on logical thought was so profound that his methods dominated Western intellectual history for over two millennia.

In Metaph. E.1, Aristotle divides the sciences (=branches of knowledge) into three divisions: Theoretical (mathematics, natural science, theology), Practical (ethics, politics), and Productive (art, rhetoric). They are distinguished by their aims—truth, action, and production, respectively. Where is logic on this list?
