when and where it does, each tends to view the other side's philosophy as misguided, and relying on philosophical considerations ends up being divisive. one could say our current two party system is "evil" : )
false dichotomy. science and philosophy are both tools we use to achieve fulfilling lives.
the term evil is too vague to be meaningful without context. science certainly has a lot to say about the negative social implications of slavery.
as with slavery science has a lot to say about negative social/psychological implications of living in a world where experimenting on live humans was allowed. otherwise without external context "bad" is just a vague, undefined term similar to evil.
"should" (and perfect) are the vague, meaningless terms here. if you define what you specifically mean by those this statement becomes a hypothesis supportable by science.
vague = "shouldn't".
obviously there are empirical reasons we shouldn't start wars if we value our own life and well being. you could say that our valuation of those things is "philosophical", but as previously harped on it is also driven by evolution so it's not all that simple.
this premise of this thread seems a bit incoherent. it's obvious science plays a big part in determining moral consensus and will continue to do so, so i'm not sure what you're actually arguing for. I know you have a huge issue with the actions of individual scientists and what you think is a broken system driven more by funding than seeking beneficial research, but that has nothing to do with the actual usefulness of science itself in determining how we can fulfill whatever goals we have.
