As I said in the OP it's important that if you're using utilitarianism you balance it with humility and with considering spiritual values, not just physical ones.
Virtue ethics may have the smallest risks, probably the main one would be people ignoring evils that they could oppose.
OK one issue I have. First off it sounds cool, but as a Muslim I believe that not all are destined to be guided.
The cool bit: people being virtuous, sociable, spiritual etc.
The uncool bit: the real world where people aren't always like that.
As a Muslim my angle is I have a decent community to co-exist with.
But "out there" in the community due to peoples vices no matter how much one preaches or appreciates spiritual values etc, theyre often left to hover in the abstract, because it seems that there will always be uncool people.
So, philosophy often remains an abstraction. It could be cool, it may even sound great, but there is the real world. People don't measure up.
So, in that sense its so much talk and chatter. Will God judge us on our ideals or on our real lives? I think there will be a balance.
I have read about IIRC P Abelard, AFAIK he said God will judge not according to actions but ones highest ideals, independent of situation and strength of will to implement them etc. But what are ideals good for if they cant be implemented.
My belief is that God wants to do justice, which is why He permits diversity, and will reward some and not others.
Thats the state of play. Not all will cooperate with what is right.
Although one can say "not all will be pious according to Muslim standards too, as with philosophical ones" which is a true and valid point, at least I have some form of consistency and community where people share the same way.
Just as a Church is a bit of a retreat from 'the world' also.
Once one gets into philosophy there is so much diversity that one cant expect common agreement with even ones friends. So such philosophical friendships tend to value tolerance and respect of diversity, at the expense of a common world perspective.
Like, if you go to church and chat about deontics etc, half the people wont even register what deontology means.
So, I wonder what good is philosophy?
Believers of all creeds tend to have meeting places, assemblies, churches, temples etc.
Philosophers tho, what do they have?
So, maybe one point is if you mix faith and philosophy too much, its potentially a splintering influence?
