The war on reason

“Scientists and philosophers argue that human beings are little more than puppets of their biochemistry. Here’s why they’re wrong.” This is Paul Bloom’s very good review of neuroscience’s claim that we are biochemical puppets and social psychology’s demonstration that factors we are unaware of influence our thoughts and acts. But Bloom concludes: “Yes, we are physical beings, and yes, we are continually swayed by factors beyond our control. But as Aristotle recognized long ago, what’s so interesting about us is our capacity for reason, which reigns over all. If you miss this, you miss almost everything that matters.”

Time travel and killing Hitler

Time travelers: please don’t kill Hitler. One of the most popular mind experiments for exmining theories of knowledge and theories of reality is time travel. And for time travelers, one of the most common scenarios (perhaps the most common) is killing Hitler. But … “in almost any science-fiction scenario involving time-travel, the default action is to kill Hitler. As terrible a human being as he was, there are many reasons why this probably isn’t a good idea.”

Should we redesign humans?

… or, for that matter, monkeys? “Say you did create a human-chimp chimera that was like a dog, but much, much smarter. It loved you unconditionally and did what you wanted and was a sort of slave, but it enjoyed it. Does that being have a complaint against you? If it hadn’t been created in that way, it wouldn’t have existed. In that sense, it’s not harmed.”
