The significance of observation for our humanity cannot be overstated. It is only through observation, through perception in general, that we become aware of reality and the wonder of creation. Scientific knowledge is based on observation, just as the all-encompassing, joyful vision of the mystic is. This is vividly illustrated in this small, beautifully designed book by a scientist, the father of LSD, using the example of experiencing nature in his old age on a Jura forest meadow. Albert Hofmann had this book produced in a limited edition for his family and friends on the occasion of his 90th birthday, featuring enchanting photographs of butterflies, all taken on his property. This collection of poems, aphorisms, and timeless thoughts is a testament to a remarkable personality.
