On these three considerations alone is based the conception of irresponsibility for crimes and the extenuating circumstances admitted by all legislative codes. The responsibility appears greater or less according to our greater or lesser knowledge of the circumstances in which the man was placed whose action is being judged, and according to the greater or lesser interval of time between the commission of the action and its investigation, and according to the greater or lesser understanding of the causes that led to the action.

Thus our conception of free will and inevitability gradually diminishes or increases according to the greater or lesser connection with the external world, the greater or lesser remoteness of time, and the greater or lesser dependence on the causes in relation to which we contemplate a man’s life.
