Fiat Lux. —Genesis 1:1
In earlier times, when life, or rather the perception of life, was simpler, the nature of light was felt to be a God-given "obvious" entity. However, as knowledge evolved, the complicated nature of this phenomenon became more apparent, to such an extent that earlier in this century its complexity appeared to be unfathomable.
Two perfectly valid groups of experiments, giving strikingly opposite results, were then showing light to be "either" a corpuscle "or" a wave, thus creating much confusion. Quantum theory solved this apparent contradiction by devising sets of equations representing light to have the capacity to act both as a wave "and" as a corpuscle. This formulation was a close enough representation of an intrinsic reality to be fully operational and to allow for further major advances in physics.
I believe that studies of the nature of psychopathology and its related therapeutics can benefit from the analysis of such a conceptual evolution. In this book, Dr. Schad-Somers is, in fact, following a similar approach by showing the critical importance of psychosocial and biological factors in mental health. Each human being can be seen as a unique blend of these ever-evolving, ever-interacting components which cannot be artificially separated without risks. This notion is equally crucial to people like Dr. Schad-Somers, who is a psychotherapist, and to those who,
