When Michael Pollan was preparing to investigate the use of drugs in the treatment of depression, addiction and anxiety, which are so difficult to overcome, he did not intend to create what turned out to be the most personal of his books. But finding that these substances can improve the quality of life not only mentally ill, but also quite healthy people, barely restraining the pressure from everyday life, he decided to determine the topography of his own consciousness and wrote a lot from the first person. Thus began his journey through various altered states, during which he turned to the achievements of brain science. Pollan also worked hard in the archives to separate the truth about psychedelics from the common myths that have dominated perceptions of them since the 1960s, when negative attitudes were lobbied for what had the potential for science. It is a unique combination of history, medicine and science with biographical episodes, an exciting description of personal experience, referring to a new frontier in our understanding of the mind, personality and place in the world. The true theme of Pollan’s “psychedelic herbologist” is not only psychedelics, but also the unsolvable mystery of human consciousness as in a world confronting us with suffering and pleasure, we can find meaning in our lives.
