When scientists need to explain difficult points of theory, illustration by hypothetical example - rather than by total abstraction - works well (perhaps indispensably) as a rhetorical device. Such cases do not function as speculations in the pejorative sense - as silly stories that provide insight into complex mechanisms - but rather as idealized illustrations to exemplify a difficult point of theory. (Other fields, like philosophy and the law, use such conjectural cases as a standard device.)

I want to build vast machines of light and darkness, intricate mechanisms within mechanisms, a progression of gears and cogs and pistons each working to its own end as well as that of the Greater Device. That's what I see in my head. But, too often, I sense that many readers want nothing more complex or challenging than wind-up toys. It's dispiriting.

If the alternative that's being offered to what physicists now talk about - a big bang, a spontaneous singularity which gave rise to the origin of the universe - if the alternative to that is a divine intelligence, a creator, which would have to have been complicated, statistically improbable, the very kind of thing which scientific theories such as Darwin's exists to explain, then immediately we see that however difficult and apparently inadequate the theory of the physicists is, the theory of the theologians - that the first course was a complicated intelligence - is even more difficult to accept. They’re both difficult but the theory of the cosmic intelligence is even worse. What Darwinism does is to raise our consciousness to the power of science to explain the existence of complex things and intelligences, and creative intelligences are above all complex things, they’re statistically improbable. Darwinism raises our consciousness to the power of science to explain how such entities - and the human brain is one - can come into existence from simple beginnings. However difficult those simple beginnings may be to accept, they are a whole lot easier to accept than complicated beginnings. Complicated things come into the universe late, as a consequence of slow, gradual, incremental steps. God, if he exists, would have to be a very, very, very complicated thing indeed. So to postulate a God as the beginning of the universe, as the answer to the riddle of the first cause, is to shoot yourself in the conceptual foot because you are immediately postulating something far far more complicated than that which you are trying to explain. Now, physicists cope with this problem in various ways, which may seem somewhat unconvincing. For example, they suggest that our universe is but one bubble in foam of universes, the multiverse, and each bubble in the foam has a different set of laws and constants. And by the anthropic principle we have to be - since we’re here talking about it - in the kind of bubble, with the kind of laws and constants, which are capable of giving rise to the evolutionary process and therefore to creatures like us. That is one current physicists’ explanation for how we exist in the kind of universe that we do. It doesn’t sound so shatteringly convincing as say Darwin’s own theory, which is self-evidently very convincing. Nevertheless, however unconvincing that may sound, it is many, many, many orders of magnitude more convincing than any theory that says complex intelligence was there right from the outset. If you have problems seeing how matter could just come into existence - try thinking about how complex intelligent matter, or complex intelligent entities of any kind, could suddenly spring into existence, it’s many many orders of magnitude harder to understand.

In this crucial sense, the theory of punctuated equilibrium adopts a very conservative position. The theory asserts no novel claim about modes or mechanisms of speciation; punctuated equilibrium merely takes a standard microevolutionary model and elucidates its expected expression when properly scaled into geological time.

... a certain amount of arrogance is essential in carrying forward an idea. In talking about the device with others, it is surprising now in retrospect the number of people who either were quite negative and had reasons to suggest it would not function as described or claimed that it would be of little interest and no better than some already existing device.

 

Willard Boyle

 

Good design is also an act of communication between the designer and the user, except that all the communication has to come about by the appearance of the device itself. The device must explain itself.
