Have Humans ‘Won’ Evolution?

In the comments of my last post on evolution and the source of moral law, I had a bit of a back and forth with Matt about whether evolution favors altruism.  I want to single out his comments for two reasons.  First, I thought he displayed admirable humility in admitting he didn't have the evidence to back up his intuition.  A lack of data didn't mean he had to give up his opinion (after all, scientists usually aren't agnostic about what experimental results they expect) and he did a nice job … [Read more...]

This is one of a series of posts about math and morality.  I'll be getting back to the series soon, but I'm currently pausing to answer some of the questions that have been accumulating.

Crowhill: Does there have to be some sort of "objective morality" for a dog to know how he's supposed to behave towards other dogs? Isn't it entirely possible that dogs … [Read more...]

“Only animals can’t help what they are”

For an explanation of what Weatherwax Wednesdays are all about, read the introduction post. This week's Weatherwax quote is also from Carpe Jugulum. This exchange occurs between during the denoument as Granny Weatherwax confronts the leader of the vampire family that has invaded the kingdom of Lancre. “We are vampires.
