Part 1578
g: but things that are such relatively, vary according as they are compared with different things. For what is big in comparison with one thing, is small in comparison with another. Now a thing is said to be voluntary, not only for its own sake, as it were absolutely; but also for the sake of something else, as it were relatively. Accordingly, nothing prevents a thing which was not voluntary in comparison with one thing, from becoming voluntary when compared with another.
* Reply to Objection 3: * That which is done through fear, is voluntary without any condition, that is to say, according as it is actually done: but it is involuntary, under a certain condition, that is to say, if such a fear were not threatening.

* I answer that, * Concupiscence does not cause involuntariness, but on the contrary makes something to be volun
