When religion and morality fail... who ya gonna call?

Mankind has, for the last couple thousand years, accepted morality, mostly in the form of religion. Note the paralells between religious texts and our judicial system (the 10 commandments, for example). This has certainly not been it's only influence but it is apparent that it has had considerable scope.

This was not bad! It is not bad still. It is important that we act in a moral manner (or, in a manner that so far morality has made us act) for the most crass of reasons, our society would not function as well without morality. Societies that don't function well go the way of the Dodo.

Unfortunately, both morality and religion rely on faith. This is not to say they are incorrect but they are incompatible with a belief system arising entirely from reason and logic alone. They must be believed inherent; logic and reason will not allow this.

What then is our answer? Where do we turn to for decisions on how to act? I am not very familiar with Social Contract, is this what Locke was talking about? Philosophy seems like it could provide answers. What are they?
