The fallacy of necessity attributes unwarranted inevitability to a conclusion, derived from the inevitability of its premises.
Der Trugschluss der Notwendigkeit schreibt einer Schlussfolgerung eine unnötige Unvermeidlichkeit zu, die von der Unvermeidlichkeit ihrer Prämissen herrührt.
| Fallacy | Fallacy of necessity |
|---|---|
| Definition and Examples | Fallacy where a degree of unwarranted inevitability is placed in the conclusion based on the inevitability of its premises. a) Bachelors are necessarily unmarried. b) John is a bachelor. Therefore, c) John cannot marry. The condition a) appears to be a tautology and therefore true. The condition b) is a statement of fact about John which makes him subject to a); that is, b) declares John a bachelor, and a) states that all bachelors are unmarried. Ex: a) Vegetarians neccesarily cannot eat meat. b) You are a vegetarian c) Therefore, you can not eat meat (obviously I could eat whatever I want) |
