Abstract
. — The scientific method can be understood as a sequence of stages of types of activity undertaken to construct explanatory hypotheses which are verifiable. These stages, origination, deduction, experimentation, and confirmation, are each subdivided into several phases. The stages and phases are related by an order of precedence in which any given phase has to be preceded by the one before it but does not necessarily lead to the one after it. Such a dynamic outline of the growth of a scientific idea is a general scheme for rendering an explanation of it. As a consequence, the general historical development of a scientific idea is traced at the same time that its logical structure and operational significance is indicated
