Subtitled A View of the World, Man and God, this is a parody by a German Jewish philosopher who achieved some recognition in the late nineteen tens and twenties- mainly for his major work The Star of Redemption. Understanding the Sick and Healthy is relatively short, was written in 1921 and has never before been published. In medical terms it is, as its introduction states, an attack on the old speculative, conceptual philosophies which tend to reduce reality to the perceiving self and try to uncover ""essentials"". As an adherent of this way of thought, the patient is struck with a paralysis and goes to a sanitorium surrounded with three symbolic mountains- the World, Man and God. There he comes to the realization that only through common sense- by using his five senses fully- can he relate these three ultimate parts of reality. An interesting facet of German philosophy. Medically it seems dated.
