Morals are the most practical behavior possible.
There is something I saw on TV as a boy that made a profound impression on me, it was an ultimate expression of love, which is the highest moral good:
That man dove repeatedly into an icy river to save those he did not know in an air crash in the Potomac, and he died in the process.
Was he being "practical"?
Richard Dawkins explains it thusly: Evolutionary adaptaations sometimes misfire. An adaptation which was for a particular purpose often gets used in a different way. For example sexual pleasure evolved to propagate the species. People and animals only have sex because they enjoy it. If the experience was wholly neutral, neither people nor animals would bother doing it. Yet today we have artificial contraception. We still feel the pleasure, but the evolutionary reason, conception, is not achieved. With contraception we get little or no evolutionary benefit anymore from our sexual urges.
Similarly, morality can be said to have evolved out of a need for practicality or social cohesion. Yet today we have artificial cities and communities where most people we meet are strangers, far from hunter-gatherer societies where almost everyone you met was either a relative, or a person connected to you in some way. We still feel the desire to help those we don't know, even though it won't bring us any personal benefit. In a large city we get little or no benefit from our urge to do good to others.
The modern artifices of life have changed the way we behave. Originally practical adaptations have taken on different roles and consequences in the modern community in which we live.
Deputy Dog: They use my world view for their morals.
In a way, yes, I agree that many modern Western societies use Christianity as a basis for many laws and moral decisions.
Yet, many of the moral codes existed before Christianity came on the scene. In addition, much of the Jewish system of law originated in Egypt.
Further, non-Christian nations such as Japan, where I now live, have a highly developed system of morals with practically zero historical influence from Christianity. Japanese society has a well constructed notion of right and wrong, and moral and ethical educationas a compulsory subject in schools. Many well-educated people are also fascinated by the similarities and differences between it and the western morality.
