It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed (Aquinas).

To treat others ethically is to act out of concern for their happiness and suffering.

As an atheist, I am angry that we live in a society in which the plain truth cannot be spoken without offending 90% of the population.

Hope is easy; knowledge is hard. Science is the one domain in which we human beings make a truly heroic effort to counter our innate biases and wishful thinking. Science is the one endeavor in which we have developed a refined methodology for separating what a person hopes is true from what he has good reason to believe.

We have Christians against Muslims against Jews. They're making incompatible claims on real estate in the Middle East as though God were some kind of omniscient real estate broker parsing out parcels of land to his chosen flock. People are literally dying over ancient literature.

I consistently encounter people in academic settings and scientists and journalists who feel that you can't say that anyone is wrong in any deep sense about morality, or with regard to what they value in life. I think this doubt about the application of science and reason to questions of value is really quite dangerous.

It is taboo in our society to criticize a persons religious faith... these taboos are offensive, deeply unreasonable, but worse than that, they are getting people killed. This is really my concern. My concern is that our religions, the diversity of our religious doctrines, is going to get us killed. I'm worried that our religious discourse- our religious beliefs are ultimately incompatible with civilization.
