Ascesis Quotes

There's a necessity for physical experience and a recourse to exemplary cases of bodily ascesis to understand and make understood a type of emptying of the mind, an emptying that is required if the mind is to think. This obviously has nothing to do with tabula rasa, with what Descartes (vainly) wanted to be a starting from scratch on the part of knowing thought. (Jean-François Lyotard)
81. Agape is the progeny of apatheia. Apatheia is the very flower of ascesis. Ascesis consists in keeping the commandments. The custodian of those commandments is the fear of God which is in turn the offspring of true faith. Now faith is an interior an interior good, one which is to be found even in those who do not yet believe in God. View quote
Evagrius Ponticus
To my eyes, only the ascesis of scientific rigor, this detachment from oneself which requires an objective and impartial judgment, can give us the right to implicate ourselves in history, to give it an existential sense. View quote
Pierre Hadot
Descartes, I think, broke with this when he said, "To accede to truth, it suffices that I be any subject that can see what is evident." Evidence is substituted for ascesis at the point where the relationship to the self intersects the relationship to others and the world. The relationship to the self no longer needs to be ascetic to get into relation to the truth. It suffices that the relationship to the self reveals to me the obvious truth of what I see for me to apprehend the truth definitively. Thus, I can be immoral and know the truth. I believe this is an idea that, more or less explicitly, was rejected by all previous culture. Before Descartes, one could not be impure, immoral, and know the truth. With Descartes, direct evidence is enough. After Descartes, we have a nonascetic subject of knowledge. This change makes possible the institutionalization of modern science. View quote
