Keiji Nishitani was a Japanese philosopher of the Kyoto School and a disciple of Kitaro Nishida. In 1924 Nishitani received a Ph.D. from Kyoto University for his dissertation Das Ideale und das Reale bei Schelling und Bergson.
He studied under Martin Heidegger in Freiburg from 1937-9. He held the principal Chair of Philosophy and Religion at Kyoto University from 1943 until becoming Emeritus in 1964. He then taught philosophy and religion at Otani University.
At various times Nishitani was a visiting professor in the United States and Europe.
According to James Heisig, after being banned from holding any public position by the United States Occupation authorities in July 1946, Nishitani refrained from drawing "practical social conscience into philosophical and religious ideas, preferring to think about the insight of the individual rather than the reform of the social order."
Fascinating book of lectures from, what I think to be, the best of the Kyoto School philosophers.
Not hard to read or understand, however, this is coming from a person that has studied Buddhism and the philosophy of religion for years (in and out of University).
I would only hope more untranslated works of Keiji Nishitani are translated or I ramp up my Japanese study to be able to read the source texts. I hope the latter will come true but I'm not against the former either.
