A fortiori

A fortiori. The argument à fortiori, from the stronger, consists in inferring from the greater case to the less, e. g. inferring the operation of a cause in a less difficult case from its operation in a more difficult one, the superiority or inferiority of one thing to another from its superiority or inferiority to that which is superior or inferior to it, and the like.


It has been pronounced impossible to exhibit à fortiori reasoning in regular syllogistic form, and such arguments have been even entitled syllogisms without a middle term. I have however maintained, and I venture to think proved the contrary.(1)
