Aquinas’ treatise on conscience was the culmination of a lengthy debate that had been going on for centuries. This debate is today known and carried on under the name “weakness of the will” or akrasia. In my article, I am aiming to demonstrate that this discussion, which started with the Aristotle's problem of incontinent (akratic) man, has been going on through Augustine's problem of “two wills”. I would like to demonstrate that Aquinas links this discussion to his conception of the conscience and synderesis. Despite the fact, that R. Saarinen in his book about “weakness of the will” proves there is no connection between Aristotle's incontinent (akratic) man and Augustine's problem of “two wills”, my aim is to explain that it is Aquinas himself who connects Aristotle's incontinent man with Augustine's “two wills” and that incontinent person is someone who acts against his conscience.

19 The concept “synderesis” (it would be better to say syneidésis because synderesis had arisen from the wrong transcription) was used for the first time by Jerome (347–419) in his commentary on Ezekiel (Commentaria in Ezechielem prophetam 1,1, c. 1, PL 25,22b). Jerome explained Ezekiel's vision of four animals (human, lion, ox, and eagle) in the manner of Plato as the four powers of the soul: reason, irascibility, concupiscence and conscience, although the conception “conscience” did not play a part in Plato's description of the soul. According to Jerome conscience is a spark of reason called by Greek synderesis. Synderesis is, according to Jerome, the ability of the soul which was not touched by original sin; the soul is able to judge, what is right or wrong, because of conscience; and so the soul is able to direct the person's actions.

42 This is also why the kind of ethic judgment differs from the kind of judgment that would be derived solely from a particular or concrete situation. The judgments of ethic belong to the speculative science while the judgment as to matters of conduct is connaturalis.
