Too many Americans have twisted the sensible right to pursue happiness into the delusion that we are entitled to a guarantee of happiness. If we don't get exactly what we want, we assume someone must be violating our rights. We're no longer willing to write off some of life's disappointments to simple bad luck.

I think very few people realize how much the separation of church and state has to do with the fact that Americans are not only more religious than a lot of other people in the world but that conversions are much more common here.

People think that, that conversion to Judaism is just a modern phenomenon. But there was an era in the late Roman Empire Judaism was not a proselytizing religion. It didn't go out looking for converts, but it accepted converts.

Every brand of religion maintains, and is, a permanent mechanism for transmitting ideas and values - whether one regards those values as admirable or ridiculous. Secularist organizations, with their generally looser, nonhierarchical structures, lack the power to hand down and disseminate their heritage in such a systematic way.

I wanted to know how much of conversion was forced - that is, forced in the sense that the Inquisition forced people to choose - forced Jews, let's say, and Muslims to choose conversion to Christianity or death. I wanted to see how much of conversion historically was forced in that way and how much of it was really a kind of persuasion.

Religious education is only valuable intellectually, if the child is educated in a religion versus [just] about a religion. I don't believe you can have both.

The Roman Empire was fairly tolerant of religious choice as long as you made a point not of thumbing your nose in public at the Roman gods.
