'Where does morality come from, if not from God' you may ask, regarding the claim of this group's name?

Two places: evolution and secular reasoning... Despite the notion that beasts behave only like unthinking 'beasts', scientists studying our primate relatives, such as chimpanzees, see evolutionary rudiments of morality: behaviors that look for all the world like altruism, sympathy, moral disapproval, sharing — even notions of fairness. This is exactly what we'd expect if human morality, like many other behaviors, is built partly on the genes of our ancestors (we share a common ancestor with the Chimpanzee as we are also a species of primate, we also are known as mammals an share a common ancestor with all other mammals).

The conditions under which humans evolved are precisely those that would favor the evolution of moral codes: small social groups of big-brained animals. When individuals in a group can get to know, recognize and remember each other, this gives an advantage to genes that make you behave nicely towards others in the group, reward those who cooperate and punish those who cheat. That's how natural selection can build morality. Secular reason adds another layer atop these evolved behaviors, helping us extend our moral sentiments far beyond our small group of friends and relatives — even to animals.

Should we be afraid that a morality based on our genes and our brains is somehow inferior to one handed down from above? Not at all. In fact, it's far better, because secular morality has a flexibility and responsiveness to social change that no 'God-given' morality could ever have. Secular morality is what pushes religion to improve its own dogma on issues such as slavery and the treatment of women. Secular morality is what prevents ethically irrelevant matters — what we eat, read or wear, when we work, or whom we have sex with — from being grouped with matters of genuine moral concern, like rape and child abuse. And really, isn't it better to be moral because you've worked out for yourself — in conjunction with your group — the right thing to do, rather than because you want to propitiate a god or avoid punishment in the hereafter?

Nor should we worry that a society based on secular morality will degenerate into lawlessness. That experiment has already been done — in countries such as Sweden and Denmark that are largely filled with non-believers and atheists. I can vouch from experience that secular European nations are full of well-behaved and well-meaning citizens, not criminals and sociopaths running amok. In fact, you can make a good case that those countries, with their liberal social views and extensive aid for the sick, old and disadvantaged, are even more moral than America.

Clearly, you can be good without God.
