I was “dhewi” online when shorter names were better, and I’m not going to change now.

You Are You Because You Have No Free Will

Why are you reading this? For some reason, in recent weeks I keep bumping into Robert Sapolsky’s ideas. He is certain that you had no choice but to read what you’re reading, because there is no such thing as free will. You may think you chose, but there was nothing doing any choosing. Biologically, you can’t argue either – because of the evidence, not because your actions are predetermined. Whatever you do is caused by neurons firing, which are physical, and work by physical causes, combinations of sensory input, connection between them, environment and history....

Truth Is Not Important

Sometimes I annoy people by saying that truth is not important. “Truth” is always either provisional, dependent on formal assumptions, or a matter of faith. It can’t be absolute, and therefore we shouldn’t treat it as an end in itself. As sentient beings, we interact not directly with reality, but with representations and models of reality. More and more, in science, through sophisticated equipment, but at any time through our senses and brain processes....

Seeking Novelty and Getting Progress

After I wrote a little essay about life being better without planning, one of those fortunate coincidences occurred, and I found a book called “Why Greatness Cannot Be Planned”. I recommend the book.

It makes the case, from a technical and practical base, that no ground-breaking achievement can ever be achieved by deciding on the steps to get there and working through them....

Many Fools Are Better Than One Wise Person

I regularly mention, when talking about other things, that I am a great believer in “the wisdom of crowds” and democracy in the absolute. And people are regularly baffled. What, I see all the idiots around, and what they vote for, and how all around people say stupid things and are mean and terrible, and wrong … and I think that’s a good thing? I do think it’s a good thing....

Mixing with Disagreeable People for Fun and Profit

Everybody knows you shouldn’t only eat what you like. Whatever it is that you like best, a varied diet is better for you than just that thing, however healthy it may be. Some of the necessary things seem pointless or borderline harmful. Roughage, for example, goes right through you and you get nothing from it. There is strong evidence that some things that are mildly toxic prime your body in useful ways, not to mention that some elements that would be poisonous in large doses are vital in trace quantities....
