Logical fallacy

four categories of fallacy

1.Fallacy of irrelevance (不相干謬誤)

These are cases where irrelevant reasons are being used to support the conclusion.

(理由和結論沒有邏輯關係，甚至毫無關係)

2. Fallacy of insufficiency (不充分謬誤)

These are cases where the evidence supporting a conclusion is insufficient or weak.

(理由給結論的支持未達足夠有效的程度)

3. Fallacy of inconsistency (不一致謬誤)

These are cases where something inconsistent or self-defeating has been proposed.

(思考或言論有矛盾衝突、自我推翻、不一致等性質)

E.g. When the former chief executive Mr. Tung was asked to comment a TV program.He said,'I shall not comment on such distasteful program.'

4. Fallacy of inappropriate presumption (不當預設謬誤)

These are cases where we have an assumption(假定，設想) or a question presupposing something that is not reasonable to accept.

(把不能視為當然的預設視為當然)

E.g. Your friend asked you,'Have your father succeeded in breaking from the jail'.
