Why not? Are you supernatural?
you’re weeding out what you THINK are the weakest but you could be wrong.
So you are saying that Darwin (and you) have no clue as to what you mean when you say the "weakest will naturally get weeded out over time."
We’re EXTRA-natural, outside of natural processes, because we’re thinking about things. Natural processes work without thinking, they are how the seemingly chaotic world works out. Darwin and I both know what we mean when we say the weakest will naturally be weeded out, what we don’t know is if our JUDGEMENT of the weakest is ACTUALLY the weakest. It could easily wind up that what society decides is the weakest is actually strong, just look at how society generally judges the “nerds” among us and how much the “nerds” have wound up running things since the computer revolution began. You could easily see where a eugenically bent society would have weeded out the “nerds” for being physically weak and socially inept and thus prevented the last 30 years of technical growth (and even further back, you can easily argue it was the “nerds” that spawned the industrial revolution and everything that’s come since).
