This is a truly bewildering book: a presentation of a concept and treatment called ""Functional Integration"" that never really says what it is. Hanna, identified as a practitioner of F.I., makes a good point--that a ""diminished capacity for movement is equivalent to diminished life."" He argues, along current holistic lines, that any illness or dysfunction is both physical and mental: ""A somatic distortion is a distortion of one's being--not of something called the mind nor of something called the body, but of one's entire being."" He identifies four basic functions of being--standing, facing, handling, and timing--which apparently are part of an ""archesoma"" that ""knows what it needs and wants, and in the profoundest biological sense, this is also what each of us needs and wants."" And Functional Integration is a therapy (physical?) which somehow aligns these needs and wants. Hanna admits that ""like other forms of somatic education [biofeedback is one] Functional Integration is a practice that is in advance of its theory."" It seems also to be in advance of words which can adequately explain it.
