The dream of matter – Albert Hofmann’s last work before his death in 2008, at the age of 102 – presents the personal experiences and thoughts of the scientist on chemistry, natural sciences, substances that alter the mind, soul and search for happiness and meaning of life. This collection of articles, poems and aphorisms tells us among other things that the author was able to face and communicate – with lucid simplicity – complex ideas that still resonate with great authority and penetration ability.
