"A Guide to Rare Philosophy"

A philosophy introduction book for troubled modern people by the internationally acclaimed film director and rare philosopher Sojiro Sanada.

What is "Rare Philosophy"?

The original word "Philosophy" was initially translated as "希哲学" (rare philosophy). It carries the meaning of "loving wisdom." It refers to the practice of acknowledging the existence of things we don't understand in daily life, freely setting questions, digging deeper, and thinking. The great philosophers of the past were truly "rare philosophers" who loved wisdom. This book does not teach difficult theories as so-called "philosophy," but introduces the original "love of wisdom" = "rare philosophy." Through rare philosophy, it conveys tips for becoming interested in the surrounding world and enjoying daily life.

"Study," "Friends," "Dreams," "Individuality," "Beauty," "Time," "Death"---.

This book uses themes of universal life questions, borrowing words from philosophers, to explain them in a "super" easy-to-understand and pop manner. It is an introductory book on rare philosophy.
