Are you aware of the differences between the paradigms and positions? Most people aren't. Nietzsche may have been the father of postmodernism, but there are some substantial differences between his project and that of those who go under that name. Also, Nietzsche, although an atheist, had a much more rational and subtle postion than Richard Dawkins and his acolytes.
This video also concerns Bataille's negative dialectic or the exposure to "nothing". It's not at all scientific to assume that the salience of points have a fundamental existence outside of your mind.
Atheistic "mysticism" differs from religiosity a few steps further up the mountainside at the point where hope turns into despair and one's despair becomes redemptive. I'm not really arguing that one should embrace this perspective, only that it is the natural consequence to a long climb in relation to Western metaphysics. At the higher reaches of the summit, unlearning/nonknowledge becomes key to advancing, instead of requiring a further acquisition of knowledge.
The wisdom and reality-consolidating measure of shamanic laughter. Nietzsche, Marechera and Bataille all seem to recognise just how much shamanic laughter consolidates and recognises the tragic nature of life in a way that the conventional traditions of asceticism can't seem to muster. Those keep you holding on for a perfect time in an unspecified future, thus extending the illusion and the misery. Tragic laughter recognises things as they are and breaks the spell.
