Late eighteenth century apothecary boxes, thread cases from the mills of Lawrence, Victorian cigar boxes of gaudy Cuban design - all the better to house fossils.

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.)

"Our genetic makeup permits a wide range of behaviors - from Ebenezer Scrooge before to Ebenezer Scrooge after. I do not believe that the miser hoards through opportunist genes or that the philanthropist gives because nature endowed him with more than the normal complement of altruist genes. Upbringing, culture, class, status, and all the intangibles that we call "free will," determine how we restrict our behaviors from the wide spectrum - extreme altruism to extreme selfishness - that our genes permit."
