What are morals and where do they come from?

Probably an unanswerable question for the ages but I think it would be fun to discuss this topic in an, ahem, philosophical way.

Many of us don't pause when we instinctively give up our seat to en elderly person, or return a dropped wallet. Where do these unwritten rules of humanism come from? Why do we follow them? And what makes us choose and cling to the ones we do?

Religion, environment, family, society, and even if anyone is watching seem to influence our choices on which to follow and when. Are there any irreducible moral values that we can really cling to?

Hopefully we can put a dent in this doozy or at least try. Members Kat and Mark offered at the last meetup to have our next at their community rec room on Bethany and the 51. Waiting to get a definitive answer from them...

I know there are too many prospective meetups without locations but this one is solid, if only in limbo for a day or so.
