a fortiori

a fortiori [ɑ ˌfoʊrtɪˈoʊri] adv.



1.) For a still stronger reason; all the more (American Heritage Dictionary of the English Language).

Etymology: Latin : a, ab, from + fortiori, ablative of fortior, stronger.

"Of course one way of putting the deterministic case is to say that we are never really able to choose at all (and a fortiori never able to choose freely), and that this is so simply because we are determined. But it is much better to put the determinist case by saying that although we are certainly able to make choices, we never really choose freely, i.e. in a such a way that we are truly responsible for our choices and for what we subsequently do" (Freedom and Belief, Galen Strawson, 1986).

This one is a bit technical, I guess, but I'd like to eventually cover all the philosophical jargon terms as well as all the different kinds of rhetoric. Just like all the other words here, make sure you are using it correctly (and sparingly), or it will end up doing you more harm than good.
