Edited by Fujihara Tatsushi and Kurokawa So, "Tsurumi Shunsuke's Way of Thinking"

A renaissance more than 10 years after his death.
Tracing the rich "idea generation" that philosopher Shunsuke Tsurumi demonstrated throughout his long life, we search for clues to the future.

"The Shunsuke Tsurumi Archive" is a project that widely disseminates materials related to Shunsuke Tsurumi to the public. Part 1 records the entirety of the symposium "The Cosmology of Shunsuke Tsurumi" held in the autumn of 2025 in preparation for its opening.

Part 2 transcribes an entire diary kept by a young Shunsuke Tsurumi (18 years old, Fall Semester 1940) during his study abroad at Harvard University's Department of Philosophy. It also includes detailed notes and commentary by So Kurokawa (writer), who spent a long time working with Tsurumi.
