To advocate irrationality is to advocate that which is destructive to human life.

Christianity cannot erase man's need for pleasure, nor can it eradicate the various sources of pleasure. What it can do, however, and what it has been extremely effective in accomplishing, is to inculcate guilt in connection with pleasure. The pursuit of pleasure, when accompanied by guilt, becomes a means of perpetuating chronic guilt, and this serves to reinforce one's dependence on God.

Just as Christianity must destroy reason before it can introduce faith, so it must destroy happiness before it can introduce salvation.

One can be committed to conformity or one can be committed to truth, but not both.

When the atheist is told that God is unknowable, he may interpret this claim in one of two ways. He may suppose, first, that the theist has acquired knowledge of a being that, by his own admission, cannot possibly be known; or, second, he may assume that the theist simply does not know what he is talking about.

Reason is not one tool of thought among many, it is the entire toolbox. To advocate that reason be discarded in some circumstances is to advocate that thinking be discarded - which leaves one in the position of attempting to do a job after throwing away the required instrument.

I am arguing that faith as such, faith as an alleged method of acquiring knowledge, is totally invalid and as a consequence, all propositions of faith, because they lack rational demonstration, must conflict with reason.
