Abstract
The main objectives of the present paper is to present the difference between the prudent and the unscrupulous in Aristotle’s Nicomachean Ethics, or even try to understand if these two moral types differ only morally, or also rationally. It must be subjected, to this end, with: a) the presentation of prudence, cleverness and unscrupulousness; b) the presentation of the intellectual dispositions that accompany prudence, sýnesis, gnóme and noûs; c) an analysis about these dispositions: if they are actually dispositions or intellectual capacities.
