Besides, (we must) not be earnest, although the thing be altogether useful, for men make greater opposition against persons in earnest; also (we should) propose as by comparison, for what is proposed on account of something else, and is not of itself useful, men rather admit. Again, we must not propose that, which ought to be assumed, but that to which this is necessarily consequent, for men more readily concur, from the inference from this not being similarly manifest, and when this. is assumed that also, is assumed. In the last place, let the interrogator ask that, which he wishes especially to assume, for (the respondents) will at first especially deny, because most interrogators assert those things first, about which they are most in earnest.
