 Practical reasoning, then, plays a central role in the achievement of happiness, the final end for humans, and therefore in God’s plan for us. Like speculative reasoning, practical reasoning generally takes a deductive form. Just as science is the conclusion of the demonstrative syllogism, so conscience is the conclusion of a practical syllogism. The practical syllogism, like the demonstrative syllogism, contains a major premise, a minor premise and a conclusion. The major premise is drawn or deduced from synderesis. The minor premise, on the other hand, is drawn either from faith, natural reason or human positive law. From the major and minor premises, a conclusion is drawn that generates a moral obligation to act (Hoffmann 2012: 258). This inferential judgment is associated, for Aquinas, with conscience: an act—as opposed to a faculty or a habit—that includes a number of applications, such as “to witness, to bind, or incite, and also to accuse, torment, or rebuke” (Thomas Aquinas, Summa theologica I, q. 79, a. 13, corp.).
