“In a free society, one does not have to deal with those who are irrational. One is free to avoid them.”

“Often, to be free means the ability to deal with the realities of one's own situation so as not to be overcome by them.”

“The great virtue of a free market system is that it does not care what color people are; it does not care what their religion is; it only cares whether they can produce something you want to buy. It is the most effective system we have discovered to enable people who hate one another to deal with one another and help one another.”

“Free societies...are societies in motion, and with motion comes tension, dissent, friction. Free people strike sparks, and those sparks are the best evidence of freedom's existence.”

“One is a great deal less anxious if one feels perfectly free to be anxious, and the same may be said of guilt.”

“Violent, irrational, intolerant, allied to racism and tribalism and bigotry, invested in ignorance and hostile to free inquiry, contemptuous of women and coercive toward children: organized religion ought to have a great deal on its conscience.”
