Freedom would therefore be the average between insight and impulse, between understanding and lack of understanding, and its degree would to use an astronomical expression be empirically established by the "personal equation." But a few pages later we read "We establish moral responsibility upon freedom by which we only mean susceptibility to known motives according to the measure of natural and acquired reason. All such motives in spite of antagonism realise themselves in action with the inevitability of natural law, but we count upon this inevitable necessity when we deal with morals."
This second definition of freedom which is quite opposed to the first is nothing but a very weak paraphrase of Hegel's notions on the subject. Hegel was the first man to make a proper explanation of the relations of freedom and necessity. In his eyes freedom is the recognition of necessity. "Necessity is blind only in so far as it is not understood." Freedom does not consist in an imaginary independence of natural laws but in a knowledge of these laws and in the possibility thence derived of applying them intelligently to given ends. This is true both as regards the laws of nature and of those which control the spiritual and physical existence of man himself,—two classes of laws which we can distinguish as an abstraction but not in reality. Freedom of the will consists in nothing but the ability to come to a decision, when one is in possession of a knowledge of the facts. The freer the judgment of a man then in relation to a given subject of discussion so much the more necessity is there for his arrival at a positive decision. On the other hand lack of certainty arising from ignorance which apparently chooses voluntarily between many different and contradictory possibilities of decision shows thereby its want of freedom, its control by things which it should
