I love the great despisers, for they are the great adorers and arrows of longing for the other shore!
Anti-humanism is a rejection of the notion that humanity actually is
the center of the univers, not necessarily a rejection of the fact, that we are destined to perceive
ourselves as such, qua being human. It is a rejection of the notion that perceiving ourselves as the center of the universe implies, that we actually are.
Anti-humanism is a recognition of the fact, that we, as humans, actually
don't act in our own best self-interested, when we interact with the world from the 'obvious' standpoint of us being the be-all-end-all of the universe. We can fool ourselves into thinking so, of course. But that of course doesn't make it so.
The implication that anti-humanism is anti-human is flawed. It is anti-human-as-center-of-the-universe, which is what humanism actually means.
Being open to the possibility of meaning as something not necessarily limited to the human perspective is what anti-humanism actually is. It is open-mindedness in the non-corrupted sense.
It is anti-individualism, not anti-individual. The individual can still be meaningful, but in the context of something larger than him- or herself.
Maybe super-humanism is a more fitting term than anti-?
