“The Argument from Intimidation is a confession of intellectual impotence.”

“Cease being intimidated by the argument that a right action is impossible because it does not yield maximum profits, or that a wrong action is to be condoned because it pays.”

“De jure objections are arguments of claims to the effect that Christian belief, whether or not true, is at any rate unjustifiable, or rationally unjustified, or irrational, or not intellectually respectable, or contrary to sound morality, or without sufficient evidence, or in some other way rationally unacceptable, not up to snuff from an intellectual point of view.”

“There is no refuge from confession but suicide; and suicide is confession”

“A rationalist, as I use the word, is a man who attempts to reach decisions by argument and perhaps, in certain cases, by compromise, rather than by violence. He is a man who would rather be unsuccessful in convincing another man by argument than successful in crushing him by force, by intimidation and threats, or even by persuasive propaganda.”

“The core of science is not a mathematical modeling--it is intellectual honesty. It is a willingness to have our certainties about the world constrained by good evidence and good argument.”
