Logic is the normative science whose object is truth, in other words, true representations of reality.
In general, a normative science seeks knowledge of how we ought to conduct our activities in order to achieve a specific goal. To mention the other two classical examples, ethics is the normative science whose object is justice and aesthetics is the normative science whose object is beauty.
In its practical application, logic pursues knowledge of how we ought to conduct our thoughts in order to achieve the object of thinking, . That makes logic a special case of ethics, since ethics pursues fitness of action in general, and thinking is a special case of action.
