Here is a premise:
Very early, owing in part to English Protestant propagandists, the word Jesuitical came to characterize a form of argument designed less to seek the truth than to make a case, a form of argument that was aggressive and clever but perhaps not always sincere--indeed, one that was at times cunningly equivocal or downright deceitful.

Here is a hypothesis:
The word Jesuitical had come to mean an deceitful, aggressive form of argument.

Is it possible to conclude that if the premise is true, then so is the hypothesis?
yes
