Do arguments matter? For example, I don't think that claims about climate change - however valid - can legitimately lead to the claim that we ought to prevent climate change. — Andrew4Handel
If we want to go from provisional facts about reality to action, then it seems that we need to cross the "is-ought" barrier. Do facts imply anything about how we ought to act? — Andrew4Handel
If climate change would make mankind worse off, then don't you think that we, as human beings, have sufficient reason to prevent it or slow it down?
So, in a way, you can have the survival of the fittest desire or ideology, and yet the restraints will be the restraints of nature's possibilities. Society utilised massive slavery for centuries and flourished, but that ideology was defeated (at an appallingly late stage). Arguments against slavery made little impact for centuries. So we could end up with any type of weird dystopian society that nature allows regardless of counter argument. — Andrew4Handel
Yes, I don't think that arguments against slavery were very efficient. But it constitutes a factor for the sufficient reason principle, since slavery is not as popular now as it was centuries ago.
