Abstract

Aristotle, who has come to the forefront with the significant contributions to the development of logic throughout the history, has been the source of different perspectives for his subsequent studies with his philosophical system and logic. Many thinkers and logicians, including Russell, have come face to face with Aristotle and his ideas, regardless of whether they are positive or negative. The aim of this study is to explain the meaning of Aristotle's syllogism theory from Russell's point of view. In accordance with this aim, firstly the effects of the theory of syllogism on the development of logic and then Aristotle's own explanations are given. The study continues by examining the formal and contextual details of syllogism inferences from Russell's consideration. In the conclusion part, it is stated how studies in logic, which grew in size with the important contributions of Aristotle, reached a different point with the tradition in which Russell was involved. In the light of all these explanations, it will be seen that Aristotle and Russell look for ways to think correctly and consistently in their work, and they want to express the validity of inferences according to formal patterns.
