In this sphere of human existence, which is fundamentally the same as purely animal life, the content of such satisfaction is, however, of a finite and limited range. Such satiety carries with it no permanence, but moves forward without rest to a renewed sense of want. Men eat, drink, and sleep, and on the morrow are as hungry and weary as before. Man is compelled, therefore, to strive for a freedom more lasting in that element of the spiritual life which he appropriates in knowledge and volition, the sciences and his social activities. The ignorant man is unfree because he faces a world which is foreign to himself, a world which tosses hither and thither aimlessly, to which he is joined as an appendage, unable to unite that foreign world to itself, and to feel itself at home there as in its own demesne. The merest impulse of curiosity, the awakening of the love of knowledge, the lowest phase of animate unrest, and the highest grasp of philosophical insight are ultimately derived from the same source, namely, the desire to overcome every condition that is unfavourable to freedom, and to bring the world of everyday life, and that of the subject which reflects upon it, into one harmonious unity. If we consider the world of _action_ the result is the same; freedom in human action is the attempt to make positive or real the reason of the Will. Reason is realized by voluntary action through the life of the State. In a State that is differentiated through itself on any rational principle, all the laws and social institutions which belong to it are simply a realization of freedom according to their own essential determinants. This being so, the reason that belongs to any citizen discovers in such institutions its own essential life: and, so long as such is not in revolt from those laws, proceeds with them as with its own kith and kin rather than a foreign adversary. We not infrequently find licence identified with freedom. But the freedom of licence is irrational; it depends upon a choice and self-determination which has nothing to do with a rational will, but is rather the product of accidental impulses and their dependence on the world of sense and physical Nature.
