Man is always something more than what he knows of himself. He is not what he is simply once and for all, but is a process; he is not merely an extant life, but is, within that life, endowed with possibilities through the freedom he possesses to make of himself what he will by the activities on which he decides.

When in our isolation we see our lives seeping away as a mere succession of moments, tossed meaninglessly about by accidents and overwhelming events; when we contemplate a history that seems to be at an end, leaving only chaos behind it, then we are impelled to raise ourselves above history.

An ideology is a complex of ideas or notions which represents itself to the thinker as an absolute truth for the interpretation of the world and his situation within it; it leads the thinker to accomplish an act of self-deception for the purpose of justification, obfuscation and evasion in some sense or other to his advantage.

It has become obligatory to fulfil a function which shall in some way be regarded as useful to the masses...Even an articulated mass always tends to become unspiritual and inhuman. It is life without existence, superstition without faith. It may stamp all flat; it is disinclined to tolerate independence and greatness, but prone to constrain people to become as automatic as ants.
