Evolutionary biologist William Provine died recently.
They praise him for being a wonderful person, but according to his own worldview, there's no reason to be a wonderful person. I suspect much of his kindness was a residual effect of his former Christian faith and upbringing.
Likewise, I suspect he understood the drastic moral and existential cost of atheism because he had Christianity as a standard of comparison.
I basically agree with him about evolution, although there are scientists (e.g. Rupert Sheldrake, Simon Conway Morris, Michael Behe, Michael Denton) who do think there's design in evolution.
He also suffers from the tunnel vision of people who measure everything by their particular specialization. Even if he believes evolution is true, and there's no evidence for design in evolution, that hardly means there's no evidence for God's existence. That disregards all the other lines of evidence for God's existence.
Finally, I wonder if his labored speech was the result of treatment for brain cancer and the recurrence of his brain cancer.
