The internationally renowned philosopher Byung-Chul Han dedicates himself to the beauty of the Earth and nature. This is an unusual book about gardening, the seasons, romance, a changed sense of time, Kant's "Critique of Pure Reason," and Schubert's "Winterreise." One day, Byung-Chul Han decides to devote himself to gardening every day. He does this for three springs, summers, autumns, and winters. He names his Berlin garden Bi-Won (Korean for "secret garden"). The longer he stays there, the more respect he gains for the beauty of the Earth. He learns what care means and that the garden, indeed every plant, has its own sense of time. He rediscovers the wonder of the Earth, its strangeness, and its uniqueness. Han's philosophy of the garden is a declaration of love for the Earth and nature, as well as a call to humanity.
