How can we encourage other human beings to extend their moral sympathies beyond a narrow locus? How can we learn to become mere human beings, shorn of any more compelling national, ethnic, or religious identity? We can be reasonable. It is in the very nature of reason to fuse cognitive and moral horizons. Reason is nothing less than the guardian of love.

Faith does not offer a strong link between our beliefs and actual states of the world.

Science does not limit itself merely to what is currently verifiable. But it is interested in questions that are potentially verifiable (or, rather, falsifiable).

Compatibilism amounts to nothing more than an assertion of the following creed: A puppet is free as long as he loves his strings.

We have Christians against Muslims against Jews, and no matter how liberal your theology, merely identifying yourself as a Christian or a Jew lends tacit validity to this status quo. People have morally identified with a subset of humanity rather than with humanity as a whole.

Norway, Iceland, Australia, Canada, Sweden, Switzerland, Belgium, Japan, the Netherlands, Denmark, and the United Kingdom are among the least religious societies on earth. According to the United Nations' Human Development Report (2005), they are also the healthiest, as indicated by life expectancy, adult literacy, per capita income, educational attainment, gender equality, homicide rate, and infant mortality. . . . Conversely, the fifty nations now ranked lowest in terms of the United Nations' human development index are unwaveringly religious.

Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality.
