Formal Decision Theory Is an Optional Tool That Breaks When Values are Huge

Formal decision theory is a tool -- a tool that breaks, a tool we can do without, a tool we optionally deploy and can sometimes choose to violate without irrationality. If it leads to paradox or bad results, we can say "so much the worse for formal decision theory", moving on wit … | Continue reading

AI and Democracy: The Radical Future

In about 45 minutes (12:30 pm Pacific Daylight Time, hybrid format), I'll be commenting on Mark Coeckelbergh's presentation here at UCR on AI and Democracy (info and registration here). I'm not sure what he'll say, but I've read his recent book Why AI Undermines Democracy and Wha … | Continue reading

Neurons Aren't Special: A Copernican Argument

In virtue of what do human beings have conscious experiences? How is it that there's "something it's like" to be us, while there's (presumably) nothing it's like to be a rock or a virus? Our brains must have something to do with it -- but why? Is it because brains are complex inf … | Continue reading

Flexible Pluralism about Others' Interpretation of Your Philosophical Work

Daniel Dennett has died, and the world has lost possibly its most important living philosopher. [Image: Dennett in 2012] My most vivid memory of Dennett is from a long face-to-face meeting I had with him in 2007 at the Association for the Scientific Study of Consciousness (ASSC). … | Continue reading

Philosophy and the Ring of Darkness

Every Scholar Should Feel Relatively Underappreciated

Yes, all parents can rationally think that their children are above average, and everyone could, in principle, reasonably regard themselves as better-than-average drivers. We can reasonably disagree about values. If we then act according to those divergent values, we can reasonab … | Continue reading

Replika AI Recommends Jail Time for People Who Mistreat Her

Mind-Bending Science and AI Rights

Religious Believers Normally Do and Should Want Their Religious Credences to Align with Their Factual Beliefs

Next week (at the Southern Society for Philosophy and Psychology) I'll be delivering comments on Neil Van Leeuwen's new book, Religion as Make-Believe. Neil argues that many (most?) people don't actually "factually believe" the doctrines of their religion, even if they profess be … | Continue reading

The Mimicry Argument Against Robot Consciousness

Suppose you encounter something that looks like a rattlesnake. One possible explanation is that it is a rattlesnake. Another is that it mimics a rattlesnake. Mimicry can arise through evolution (other snakes mimic rattlesnakes to discourage predators) or through human design (rub … | Continue reading

The Leapfrog Hypothesis for AI Consciousness

The first genuinely conscious robot or AI system would, you might think, have relatively simple consciousness -- insect-like consciousness, or jellyfish-like, or frog-like -- rather than the rich complexity of human-level consciousness. It might have vague feelings of dark vs lig … | Continue reading

Could Someone Still Be Collecting a Civil War Widow's Pension? A Possibility Proof

In 1865, a 14-year-old boy becomes a Union soldier in the U.S. Civil War. In 1931, at age 90, he marries an 18-year-old woman, who continues to collect his Civil War pension after he dies. Today, in early 2024, she is one hundred and ten years old, still collecting that pension. … | Continue reading

Normativism about Swimming Holes, Anger, and Beliefs

In particular, beliefs are necessarily defective in a certain way if … | Continue reading

How We Will Decide that Large Language Models Have Beliefs

I favor a "superficialist" approach to belief (see here and here).

Percent of U.S. Philosophy PhD Recipients Who Are Women: A 50-Year Perspective

In the 1970s, women received about 17% of PhDs in philosophy in the U.S. The percentage rose to about 27% in the 1990s, where it stayed basically flat for the next 25 years. The latest data suggest that the percentage is on the rise again. Here's a fun chart (for user-relative va … | Continue reading
