meaning - "representational content". Thoughts, mental states, are about things. If you "believe in physics", and are coming from a naturalistic perspective, then meaning, intentionality, is one of the great conundrums, up there with sensory qualia. Computationalism offers no explanation of what it means for a bunch of atoms to be about something

What do you think of Eliezer's approach to the "meaning" problem in The Simple Truth? I find the claim that the pebble system is about the sheep to be intuitively satisfying.
