Do not seek to follow in the footsteps of the men of old; seek what they sought. --Nanzan Daishi
Shake off all the fears of servile prejudices, under which weak minds are servilely crouched. Fix reason firmly in her seat, and call on her tribunal for every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason than that of blindfolded fear. --Thomas Jefferson
Under attack, sentiments harden into dogma. --Mason Cooley
I have no quarrel with religion held sincerely but loosely. The problem is that religion tends almost invariable towards the dogmatic. For every ten sophisticated religious thinkers, there are a hundred who mindlessly follow an ossified, thoughtless shell of religion. True religious thinkers adapt to new ideas and new discoveries; dogmatists shut their eyes and plug their ears. Worse, they often try to shut our eyes and plug our ears. The true religious thinker always seeks the truth; the dogmatist is sure he already has it.
In this manner, I believe the atheist* is more a true religious thinker than the dogmatist. If God exists, we are wrong, but at least we aren't worshipping the idol that is religious dogma. For isn't that exactly what dogma is? Being dogmatic, at its best, is worshipping a man-made approximation of God. You might as well believe that a statue of Jesus created the Earth as be a young-Earth Creationist living in 21st century America.
* By "atheist" I refer to one who, like myself, believes that there is no God, but holds that belief tentatively, prepared to change his or her mind should new evidence arise in the same way that he or she would change his/her mind about the non-existence of unicorns if one were discovered. Certainly some atheists suffer from dogmatism as much as any Roman Catholic.
