Reasoning is usually divided into deductive reasoning and inductive reasoning  Deductive reasoning is based on some general principles and personal examples to draw new conclusions about the individual examples  Inductive reasoning abstracts and generalizes a certain general principle from a certain number of individual facts
But a more precise statement is: deductive reasoning is inevitability reasoning, that is, the premise is true to ensure that the conclusion is true; inductive reasoning is probabilistic reasoning, the premise only provides certain support for the conclusion, and the premise is true and the conclusion is not necessarily true
This text summarizes the difference between deductive reasoning and inductive reasoning.
