Talk:Hypothetical syllogism
From Wikipedia, the free encyclopedia
Madeline must have known the material for the test, because if a person knows the material, that person will get an A, and Madeline was one of the students that got an A
[edit] Madeline not necessarily guilty
The hypothetical syllogism used to say adeline is guilty is a 'fallacy'because the argument used is not 'valid'. This is because the argument used is a contingency and not a tautology. Let P(x) be "x knows the material", and Q(x) be "x gets an A grade". P(x)->Q(x)(an implication) has a true value even if P(x) is false and Q(x) is true.
