Humanism is absolute subjectivity. That is, not the absolute identity of the subject with the infinite, but rather the fulfillment (that is, the infinite as the 'end' and 'overcoming' of finitude).
Humanism is 'the responsible use of reason' and 'human experience in the real world' as the grounds for moral choices.
Humanism is a problematic kind of 'subjected sovereignty' whereby western man is told 'the more you refuse and submit to power, the more you are an obedient 'subject' the more your sovereignty is increased.
Humanism is a way of defining man in the not-incorrect albeit incomplete terms of human reason.
Humanism is a (flawed) ideology that suggests there is a universal essence of man. Humanism gives rise to the concept of man (or human nature, or the human subject) as an unproblematic and stable center. The idea of man must be abolished.
Humanism is a failed movement to liberate human kind from the dead weight of tradition but instead declining into a tradition itself, oppressing humankind. Humanism is dead, and good riddance.
Humanism is a problematic ideology that does not enrich man, but that restricts desire by creating submissive man.
