Rationality
We define [see page 24, rationality], right thinking, as doing the right thing given what information is known by the agent.
Rationality involves both logical inferences (natural deduction) and non-inferential decision making. One way to act rationally is reason logically on the outcomes of actions with respect to ones goals and pick the actions that maximise your rewards or reaches your desired outcomes. Alternatively some rational actions are reflexive. For example recoiling from a hot-stove is a reflex that are often more effective than a slower action after careful deliberation. Lastly sometimes there's no provably correct choice but a decision must still be made.
