Search Ideas

CR is an evolutionary theory. There's no need for correspondence in Darwinism. Therefore, we don't need it in CR either.

Wait, I've probably misunderstood but in #2228 it seemed like you thought pruning was needed for scarcity, which is needed for competition between ideas and their evolution.

And you equated pruning with the meta algorithm.

And now you say the meta algoritm/pruning is not needed for the evolution of ideas?

By the same logic, wouldn't neo-Darwinism also disqualify as a strand, since it's subsumed by Popperian epistemology?

Most people (except in Alzheimer's, etc.) don't run out of memory in the brain. If there's no scarcity for the space of ideas, why do they have to compete?

Alright, I remember the meta algorithm from your book but can't recall if you adress this criticism: If there's no need for a meta algorithm in biological evolution, why must there be one for the evolution of ideas?

Yeah that's definitely a possible medical condition, e.g. in psychosis or after having ECT. Don't think it's the best explanation for Alzheimer's though, where the loss of brain volume is so apparent.

Wait, do you view the pruning as separate from the mere competition of ideas, or simply its hardware consequences? In Darwinian evolution, competition and pruning are the same phenomena. Would expect the same for the mind.

That pruning mechanism is what constitutes natural selection in the mind.

Most people (except in Alzheimer's, etc.) don't run out of memory in the brain. If there's no scarcity for the space of ideas, why do they have to compete?

Of course, memory isn't infinite. But most people don't seem to run out of it in their lifetimes. Is it more accurate to say that ideas compete for working memory, which is scarcer?
