Revolution and insurrection must not be looked upon as synonymous. The former consists in an overturning of conditions, of the established condition or status, the State or society, and is accordingly a political or social act; the latter has indeed for its unavoidable consequence a transformation of circumstances, yet does not start from it but from men’s discontent with themselves, is not an armed rising, but a rising of individuals, a getting up, without regard to the arrangements that spring from it. The Revolution aimed at new arrangements; insurrection leads us no longer to let ourselves be arranged, but to arrange ourselves, and sets no glittering hopes on “institutions.” It is not a fight against the established, since, if it prospers, the established collapses of itself; it is only a working forth of me out of the established. If I leave the established, it is dead and passes into decay. Now, as my object is not the overthrow of an established order but my elevation above it, my purpose and deed are not a political or social but (as directed toward myself and my ownness alone) an egoistic purpose and deed
