ORIGINAL: juliaoceania quote:
ORIGINAL: eihwaz Evolution optimizes for a particular environment or, more precisely, a set of selection pressures; it is not merely change. Optimization via natural selection need not imply teleology. As the environment changes, so do the criteria for fitness. [...] some adaptations might be good for one set of conditions, but not for another, and the size of the beak changes rather quickly to suit the environment... I suppose you could see this as "optimization", I would not call it "progress". One beak is not inherently superior to another. [...] I think we mostly agree; we're just using slightly different terminology. In physical evolution, superiority is measured solely by fitness for survival and reproduction within a particular environment. Other than fitness, the phenomena wrought by evolution have no intrinsic -- e.g. moral or aesthetic -- value. I'm using the term optimization to refer to the tendency of evolution to improve fitness. quote:
ORIGINAL: juliaoceania progress insinuates that something is better than another thing Progress, on the other hand, is change measured according to specific extrinsic values and goals: Elucidating the neural basis of consciousness is good; equality of women in society is good; transparency in government is good; preventing and curing disease is good; eradication of hunger is good; preventing extremes of wealth and poverty is good. Relativity is superior to Newtonian Mechanics because understanding the nature of the universe is good. And so on. Attaining these "good" changes reflects human cultural evolution (which as you know is more Larmarckian, not Darwinian). In my earlier post, I was trying to explore the notion that "progress" is a type of value-laden optimization produced by human cultural evolution. But maybe that doesn't work after all. Interestingly, for there to be progress, it seems a society has to believe in it and define it. And not all human societies do or have. In order to recognize progress, you have to define it, and that requires an underlying set of notions of what is good. quote:
ORIGINAL: juliaoceania In fact, I am not one of these people who sees any life as inherently better than or more progressive than another. Not even cats?
