For example, everyone will die, and Zhang San is also a human being, so Zhang San will die. Among them, "everyone will die" is a general principle and a major premise. "Zhang San is a human being" is the specific situation and minor premise, and "Zhang San will die" is the conclusion.
Does it look simple? Indeed, children can master reasoning. But the problem is that the premise of this reasoning conclusion is that both the major premise and the minor premise are correct. If the premise of size is wrong, then you can't say that the result of reasoning is right. Or the inference conclusion is wrong, or the major premise is wrong, or the minor premise is wrong, or both major premise and minor premise are wrong.

As a tool for human beings to explore knowledge and pursue rationality, logic has a wide range of research.
Even the logic with the validity of reasoning as the core research content has many forms, including not only deductive logic, but also various non-deductive logic, such as inductive logic and analogical logic. Around the research of reasoning, logic also studies the concepts, judgments, arguments, basic logical laws and methods related to reasoning.
Take the logic system of Aristotle, the father of western logic, as an example. The representative work of his logic thought "On Tools" includes six articles: category, explanation, pre-analysis, post-analysis, demonstration and argument.
Among them, not only the deductive logic based on syllogism reasoning is studied, but also the category, proposition, proof, definition, deductive method, argument theory, the identification of fallacy and sophistry, and various rebuttal methods. , even involving epistemology and ontology.
