Over at Public Discourse, S. Adam Seagrave offers an objection to evolution, and Stephen Barr responds:
Sensation reigns supreme within its own domain, but its domain is not the whole of what is knowable. But Seagrave apparently thinks it is. He appears to attribute to the bare sense of sight the capacity to judge the most abstract propositions—for example, whether natural selection is capable of crafting organs as intricate as a human eye. Now, the human eye is certainly a remarkable organ, but it is an organ of sense, not of judgment. Judging truth and falsehood is the prerogative of reason, not of any bodily organ.
