Peirce's speculative story of the history of habit remains inferior to Thirdness, degenerating into individual belief (Firstness) with social rules (Secondness). The nervous sensation of habit is investigated by the physiological method of induction. The reactionary habit is caused by the emotional beliefs of the interpreter to remedy the discomfort of mind or body through energetic efforts. The variety of habits are emotional and energetic interpretants in search of logical interpretants. At a later time, Peirce developed habits into the psychological aspects, then a new discipline. Faced with the troublesome reasoning of habits, induction was re-considered as psychological abduction. Habits not merely reflect the moral truth of good habits but also provoke bad habits. Habit becomes habituality, ending in habituescence. Peirce's concept of habit interprets emotions and experiences to come to understanding (or misunderstanding). In Peirce's words, from desire (First) and pleasure (or displeasure) (Second), habits can grow into satisfaction (or dissatisfaction) (Third).
