What is logic? Definitions and concepts

1. Logic in a narrow sense refers to both the law of thinking and the discipline that studies the law of thinking, that is, logic. Generalized logic refers to laws, including thinking laws and objective laws. Logic includes formal logic and dialectical logic, and formal logic includes inductive logic and deductive logic. Logic refers to the laws and rules of thinking and is an abstraction of the thinking process. Logic in a narrow sense refers to formal logic or abstract logic, and refers to the logic of human abstract thinking; Broadly speaking, logic also includes concrete logic, that is, the logic of people's overall thinking.

2. Definition: Logic in a narrow sense refers to both the law of thinking and the discipline that studies the law of thinking, that is, logic. Generalized logic refers to laws, including thinking laws and objective laws. Logic includes formal logic and dialectical logic, formal logic includes inductive logic and deductive logic, and dialectical logic includes contradictory logic and symmetric logic. Symmetric logic is the logic of people's overall thinking (including abstract thinking and concrete thinking).

Three, logic usually has three meanings:

5. Logic, which originated from ancient Greek (logos), originally meant as "word" or "speech" (extended to "thinking" or "reasoning"). 1902 Yan Fu translated Moeller's Xue Ming, translated as "Xue Ming" and transliterated as "logic"; Because this word is separated from the Japanese word "ethics", it is also translated into "ethics" in Japanese. Traditionally, logic has been studied as a branch of philosophy. Since the middle of19th century, logic has often been studied in mathematics and computer science. The scope of logic is very wide, ranging from core themes such as the study of fallacies and paradoxes to specialized reasoning analysis such as possible correct reasoning and argumentation involving causality.
