Dawkins’ Dubious Double Weasel and the Combinatorial Cataclysm

Dawkins has successfully reduced a combinatorial explosion to a manageable problem...or has he?

In Richard Dawkins’ book, The Blind Watchmaker, he proposed a famous (and infamous) computer program to demonstrate the power of cumulative selection, known as the “Weasel program.” The program demonstrates that by varying a single letter at a time, it is possible to rapidly evolve a coherent English sentence from a string of gibberish. The way the program works is as follows: First, a sequence of characters is randomly assembled by drawing from the 26 English letters and the space. Then, one character is randomly reassigned. The resulting sequence is compared to the phrase from Hamlet, a quote uttered by Polonius: “methinks it is like a weasel.” For every character that matches, a point is scored. If the new sequence…

Evolution And Artificial Intelligence Face The Same Basic Problem

Think of the word ladder game, where we transform one word into another by changing only one letter at a time

Why Consciousness Couldn’t Just Evolve from the Mud

Dr. Kastrup has been, in Dr. Egnor’s words, “leading a modern renaissance of metaphysical idealism”—that is, reality is essentially mental rather than physical. Read More ›

Did Consciousness Evolve to Find Love?

It’s an attractive idea but it comes with a hidden price tag

If consciousness is a mere tool of human sexual selection, it is mere plumage, a pretty enticement, of no meaning or import otherwise. But then what becomes of Dr. Graziano’s own intellectual labors?

Did Consciousness “Evolve”?

One neuroscientist doesn’t seem to understand the problems the idea raises

Darwinian evolution must select physical attributes. If consciousness evolved as a mere byproduct of physical brain processes, it is powerless in itself. Thus Graziano's theories of consciousness are themselves mindless accidents.
