That the individual is of himself a world's history, and possesses his property in the rest of the world's history, goes beyond what is Christian. To… - Max Stirner

If it is the drive of our time, after freedom of thought is won, to pursue it to that perfection through which it changes to freedom of the will in order to realize the latter as the principle of a new era, then the final goal of education can no longer be knowledge, but the will born out of knowledge, and the spoken expression of that for which it has to strive is: the personal or free man. Truth consists in nothing other than man's revelation of himself, and thereto belongs the discovery of himself, the liberation from all that is alien, the uttermost abstraction or release from all authority, the re-won naturalness. Such thoroughly true men are not supplied by school; if they are there, they are there in spite of school.

Man, your head is haunted; you have wheels in your head! You imagine great things, and depict to yourself a whole world of gods that has an existence for you, a spirit-realm to which you suppose yourself to be called, an ideal that beckons to you. You have a fixed idea! Do not think that I am jesting or speaking figuratively when I regard those persons who cling to the Higher, and (because the vast majority belongs under this head) almost the whole world of men, as veritable fools, fools in a madhouse. What is it, then, that is called a "fixed idea"? An idea that has subjected the man to itself. When you recognize, with regard to such a fixed idea, that it is a folly, you shut its slave up in an asylum. And is the truth of the faith, say, which we are not to doubt; the majesty of (e. g.) the people, which we are not to strike at (he who does is guilty of — lese-majesty); virtue, against which the censor is not to let a word pass, that morality may be kept pure; — are these not "fixed ideas"? Is not all the stupid chatter of (e. g.) most of our newspapers the babble of fools who suffer from the fixed idea of morality, legality, Christianity, etc., and only seem to go about free because the madhouse in which they walk takes in so broad a space?

If a concept lacks an essence, nothing will ever be found that completely fits that concept. If you are lacking in the concept of human being, it will immediately expose that you are something individual, something that cannot be expressed by the term human being, thus, in every instance, an individual human being.
