“The sentiment on which [papal] infallibility was founded could not be reached by argument, the weapon of human reason, but resided in conclusions transcending evidence, and was the inaccessible postulate rather than a demonstrable consequence of a system of religious faith.”

“so it is with human reason, which strives not against faith, when enlightened, but rather furthers and advances it.”

“Western humanism has religious and transcendent sources without which it is incomprehensible to itself.”

“The formulation "ways to faith" could be interpreted as implying that faith is a conclusion a person may come to after pondering certain facts about the world-facts about history, nature, or consciousness. If that were the case, one could lead a person to this conclusion by presenting these facts to him and pointing out their implications. I, however, do not regard religious faith as a conclusion. It is rather an evaluative decision that one makes, and, like all evaluations, it does not result from any information one has acquired, but is a commitment to which one binds himself. In other words, faith is not a form of cognition; it is a conative element of consciousness.”

“Theism is irrational by definition, because it is not based on reason and is not reasonable. There was no evidence indicating this conclusion, yet it is a firm conviction anyway, and believers are determined not to let any evidence change their minds either. The very purpose and existence of apologetics all by itself demonstrates how theism is irrational.”

“Terrorism is not an expression of rage. Terrorism is a political weapon. Remove a government's facade of infallibility, and you remove it's people's faith.”

“The most important secular commitment is to the truth, which is based on observation and evidence rather than on mere faith. Seculars strive not to confuse truth with belief.”

“Paradoxically, some of the sources of disbelief are to be found amongst the arguments of believers. … Theologians often formulated the most dangerously skeptical arguments in their efforts to test the impregnability of their own faith, and in doing so, they unknowingly furnished atheists with ready-made weapons.”

“H. A. Lorentz has found out the Relativity theorem and has created the Relativity postulate as a hypothesis that electrons and matter suffer contractions in consequence of their motion according to a certain law. A. Einstein has brought out the point very clearly, that this postulate is not an artificial hypothesis but is rather a new way of comprehending the time-concept, which is forced upon us by observation of natural phenomena.”

“I will fight with all the weapons within my reach rather than let myself be nailed to a cross or whatever.”
