[A] skyhook is ... an exception to the principle that all design, and apparent design, is ultimately the result of mindless, motiveless mechanicity. A crane, in contrast, is a subprocess or special feature of a design process that can be demonstrated to permit the local speeding up of the basic, slow process of natural selection, and that can be demonstrated to be itself the predictable (or retroactively explicable) product of the basic process. ... [T]he physicist Steven Weinberg, in Dreams of a Final Theory (1992) ... distinguishes between uncompromising reductionism (a bad thing) and compromising reductionism (which he ringingly endorses). Here is my own version. We must distinguish reductionism, which is in general a good thing, from greedy reductionism, which is not. The difference, in the context of Darwin's theory, is simple: greedy reductionists think that everything can be explained without cranes; good reductionists think that everything can be explained without skyhooks.
Daniel Dennett
Unpredictability is in general a fine protective feature, which should never be squandered but always spent wisely. There is much to be gained from communication if it is craftily doled out - enough truth to keep one's credibility high but enough falsehood to keep one's options open. (This is the first point of wisdom in the game of poker: he who never bluffs never wins; he who always bluffs always loses.)
Daniel Dennett
