De Tijdstroom, Lochem, Netherlands (1991).
The author shows through methodological analysis that the role of science in medicine and health care is overvalued, while sound common sense is undervalued. Also in nursing and in physiotherapy the tendency exists to overvalue science at the cost of common sense. Further, the author shows that no sharp boundaries should exist between regular and alternative medicine. He warns against the uncritical acceptance of grand theories, regular or alternative, that aim to mould diverse aspects of health and disease into a common framework.
