Correct reasoning in logic must satisfy the following conditions: Repeatable: The conclusion of reasoning must be repeatedly proven, that is, different evidence or premises can be used to derive the same conclusion. 2. Congruence: The conclusion of the reasoning must be consistent with the premise of the reasoning. If the premise of the reasoning was inaccurate or inconsistent, then the conclusion of the reasoning would not be correct. 3. Correct: The reasoning must be based on correct premises. These premises must be true, reliable, and accurate. If the premise of the reasoning was not correct, then the entire reasoning would not be correct. 4. Logically correct: Inference must follow logical rules and principles, that is, inference must be consistent, correct, and repetitive. These conditions were the basic requirements for correct reasoning in logic and the principles that must be observed in the reasoning process. Only when these conditions were met could the correct reasoning be carried out and the correct conclusion be drawn.
