An overview of studies which investigate correlations between morality and religious vs. secular / atheist ideologies presented by Phil Zuckerman who is a professor of sociology and secular studies at the Claremont colleges in California, USA.

Summary: Atheists / secular people not only have morals but are even more moral than religious people.

Note: Of course moral is a matter of perspective. In this context we agree that compassion and empathy are our foundations of moral.
