Complementarity Quotes
Not one word is said here of acausality, wave mechanics, indeterminacy relations, complementarity, ... etc. Why doesn't he talk about what he knows instead of trespassing on the professional philosopher's preserves? Ne sutor supra crepidam. On this I can cheerfully justify myself: because I do not think that these things have as much connection as is currently supposed with a philosophical view of the world.
Erwin Schrödinger
Opticks was out of harmony with the ideas of 19th-century physics. ...an exposition of the "wrong" (i. e., corpuscular) theory of light,-even though it also contained many of the basic principles of the "correct" (i. e., wave) theory. Not only had Newton erred in his choice... but also he apparently had found no insuperable difficulty in simultaneously embracing features of two opposing theories. ...by adopting a combination of the two theories at once, he had violated one of the major canons of 19th-century physics... Today our point of view is influenced by the theory of photons and matter waves, or the... complementarity of Niels Bohr; and we may read with a new interest Newtons ideas on the interaction of light and matter or his explanation of the corpuscular and undulatory aspects of light.

The optimal scale of the economy is smaller, the greater (a) the degree of complementarity between natural and man-made capital; (b) our desire for direct experience of nature; and (c) our estimate of both the intrinsic and instrumental value of other species. The smaller the optimal scale of the economy, the sooner its physical growth becomes uneconomic.
Herman E. Daly
The irony, of course, is that high development theory was right. By this I do not mean that the Big Push is really the right story of how development takes place, or even that the issues raised in high development theory are necessarily the key ones for making poor countries rich. What I do mean is that the unconventional themes put forth by the high development theorists their emphasis on strategic complementarity in investment decisions and on the problem of coordination failure - did in fact identify important possibilities that are neglected in competitive equilibrium models. But the high development theorists failed to convince their colleagues of the importance of those possibilities. Worse, they failed even to communicate clearly what they were talking about. And so good ideas, important ideas, were ignored for a generation after they were first enunciated.
