Keiji Nishitani's 'Religion & Nothingness'
I just finished reading this book and it's a fascinating read for anyone interested in both Zen & western philosophy.
Nishitani argues that the 'scientific revolution' of the Renaissance embedded a profound subject-object dualism in the West by 'mechanising' nature, and the body as part of that nature.
This has created what he refers to as 'nihility' - the existential loss of meaning that a lot of Western philosophy since is concerned with, particularly the German idealists and the existentialists. But he says that this standpoint is condemned to always view that nihility as something seperate from the subject, meaning it can never be resolved, since that duality is precisely the root of the issue.
Instead, nihility can only be overcome through sunyata - by 'emptying emptiness' of itself.
As someone who got into Western philosophy when I was younger and found no true resolution in my experience through it, only coming to Zen afterward, this really resonated me.
I will say though its a hard, dense book. His writing has got way more in common with a Hegel than it does a Dogen, for sure.
But well worth the read. I highly recommend it.
