"In Darwin's time all of biology was a black box: not only the cell, or the eye, or digestion, or immunity, but every biological structure and function because, ultimately, no one could explain how biological processes occurred"
About this Quote
The subtext is a quiet critique of Darwin’s explanatory power. By stacking examples - “the cell, or the eye, or digestion, or immunity” - Behe isn’t merely listing topics; he’s building a sense of total ignorance, then implying that natural selection’s early victories were achieved with the crucial part of the case missing. “Ultimately” sharpens the claim into a sweeping judgment: Darwin couldn’t explain “how biological processes occurred,” so his account was necessarily superficial.
Context matters because Behe is a central figure in the intelligent design movement. This line functions like stage-setting: if Darwin worked without mechanisms, then modern mechanistic detail becomes a potential pressure point against evolutionary explanations. Even if evolutionary biology has, in fact, built those mechanisms in layers over the past century, Behe’s rhetorical move is to reframe the progress as a challenge: now that we can see inside, do we like what we see?
