The Church of Rationality

You can believe in whatever you want, but if you want to believe in the truth -- you must be rational.

  "In the absence of compelling reasons to believe, unbelief should be preferred."

"The ultimate goal of logic is knowledge of reality, and avoidance of illusion. Logic is only incidentally interested in the less than extreme degrees of credibility. The reference to intermediate credibility merely allows us to gauge tendencies: how close we approach toward realism, or how far from it we stray."


"In the absence of compelling evidence, unbelief should be preferred."

There just can be no logical belief in a God without direct evidence.

"In the event of contradictory evidence, the concept that can contain the others should be preferred."

Evidence of a young universe can be explained within the concept of an old universe, while evidence of an old universe cannot be explained within the concept of a young universe.  You can fit something small within something large, but you cannot fit something large within something small.  Given all the evidence we have of the age of the universe both young and old, the older concept must be preferred.

"The explanation that maintains the most overall simplicity while giving preference to the least hypothetical causes is preferred."

Any explanation that relies upon evidence is more likely to be correct than explanations that rely  only upon imagination.

"You can't prove a negative" is a false statement.  It would be more proper to say "You can't prove a universal negative," however that is not completely true either.   The axiom should really be "You can't prove a universal assertion empirically." It simply makes no difference if the claim is positive or negative; it is only the universality of the claim that makes it not provable by examination (empirical proof).  However, it is possible to disprove something if it constitutes a self-contradiction, which leads us to our next axiom:

"Nothing that constitutes a self-contradiction can exist."

"If there was ever a time there was nothing, there would be nothing now."


"I contend that we are both atheists. I just believe in one fewer god than you do. When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours." -- Stephen Roberts

"I wish to propose for the reader's favourable consideration a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true." -- Bertrand Russell

"We shall not believe anything unless there is reasonable cause to believe that it is true" -- Ingemar Hedenius
