Thomas JeffersonShake off all the fears and servile prejudices under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a god; because, if there be one, he must more approve the homage of reason, than that of blindfolded fear... Your own reason is the only oracle given you by heaven, and you are answerable not for the rightness but uprightness of the decision.
Thomas JeffersonTo talk of immaterial existences is to talk of nothings. To say that the human soul, angels, god, are immaterial, is to say they are nothings, or that there is no god, no angels, no soul. I cannot reason otherwise: but I believe I am supported in my creed of materialism by Locke, Tracy, and Stewart. At what age of the Christian church this heresy of immaterialism, this masked atheism, crept in, I do not know. But heresy it certainly is.

No irregular passions, no dangerous bias, which may render problematical the future fortunes and happiness of our descendants.
