"Introduction. Motivation is familiar to each of us. We feel motivated from within, by experiencing mental states that we can define as motivational states. We try to explain both our own motivation and the motivation of others in terms of folk psychology. There are many hypothetical explanations as to what lies behind behavior and what motives drive others. In this paper, we are focused on situations where the law stands behind the motivation, which is understood as internal states that direct one’s behavior towards a certain effect. This effect may involve maintaining the current state, or transitioning to a subjectively better one. We will refer to the set of all internal states and the circumstances that affect them as the motivational process."(...)
