A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

Thomas S. Kuhn's classic book is now available with a new index.

I will use the history of phage to focus on the issue of biological explanations; on the relationship between biology and physics; and on the historical problem of the disciplinary autonomy of biology, versus its reduction, which ultimately seeks to place it within the domain of the physical sciences. Paradoxically, the two physicists I focus on most, Neils Bohr and Max Delbrück, represent attempts to preserve the autonomy of biology, each in a very complex way. Once again the problematique here (...) is the nature of biological systems as goal-oriented historical phenomena, that is, as teleological explanations rather than mechanistic accounts of life.
