Theory I Foreshadowings:

Core themes and controversies in the early Freudian theories
WithSeligman Stephen

The grand themes of the most creative and original philosophical and ­scientific systems are articulated in their core controversies as much as in their direct elaboration. The limitations, omissions, and sensitive points mark their most generative dimensions. Newton’s classical physics, for example, proved unable to accommodate many of the problems and data that subsequently emerged, bringing forth the questions that spawned Einstein’s relativity theories, which have themselves been subject to new paradigm shifts. Such processes are at the core of scientific change (Kuhn, 1970): new ideas generate a set of new questions which the earlier models may not have anticipated, often in such a way as to affirm their essential value.
