“Commitment is a state of being in which an individual becomes bound by his actions and through this actions to beliefs that sustain his activities and his own involvement.”

The Ethics of Belief (1877), The Duty of Inquiry
Context: No man holding a strong belief on one side of a question, or even wishing to hold a belief on one side, can investigate it with such fairness and completeness as if he were really in doubt and unbiased; so that the existence of a belief not founded on fair inquiry unfits a man for the performance of this necessary duty.
Nor is it that truly a belief at all which has not some influence upon the actions of him who holds it. He who truly believes that which prompts him to an action has looked upon the action to lust after it, he has committed it already in his heart. If a belief is not realized immediately in open deeds, it is stored up for the guidance of the future. It goes to make a part of that aggregate of beliefs which is the link between sensation and action at every moment of all our lives, and which is so organized and compacted together that no part of it can be isolated from the rest, but every new addition modifies the structure of the whole. No real belief, however trifling and fragmentary it may seem, is ever truly insignificant; it prepares us to receive more of its like, confirms those which resembled it before, and weakens others; and so gradually it lays a stealthy train in our inmost thoughts, which may someday explode into overt action, and leave its stamp upon our character for ever.

A Treatise on Man and the Development of His Faculties (1842)
Context: The analysis of the moral man through his actions, and of the intellectual man through his productions, seems to me calculated to form one of the most interesting parts of the sciences of observation, applied to anthropology.

1930s
Context: Political power, in my opinion, cannot be our ultimate aim. It is one of the means used by men for their all-round advancement. The power to control national life through national representatives is called political power. Representatives will become unnecessary if the national life becomes so perfect as to be self-controlled. It will then be a state of enlightened anarchy in which each person will become his own ruler. He will conduct himself in such a way that his behaviour will not hamper the well-being of his neighbours. In an ideal State there will be no political institution and therefore no political power. That is why Thoreau has said in his classic statement that "that government is the best which governs the least". [From Hindi] Sarvodaya, January, 1939

The Analects, The Doctrine of the Mean
Context: Earnest in practicing the ordinary virtues, and careful in speaking about them, if, in his practice, he has anything defective, the superior man dares not but exert himself; and if, in his words, he has any excess, he dares not allow himself such license. Thus his words have respect to his actions, and his actions have respect to his words; is it not just an entire sincerity which marks the superior man?
