I will _not_ sacrifice my reason; because this reason alone enables me to distinguish good from evil, truth from falsehood. If, as you say, my reason comes from God, I shall never believe that a God, whom you call good, has given me reason, as a snare, to lead me to perdition. Priests! do you not see, that, by decrying reason, you calumniate your God, from whom you declare it to be a gift. I will _not_ renounce experience; because it is a guide much more sure than the imagination or authority of spiritual guides. Experience teaches me, that enthusiasm and interest may blind and lead them astray themselves; and that the authority of experience ought to have much more influence upon my mind, than the suspicious testimony of many men, who I know are either very liable to be deceived themselves, or otherwise are very much interested in deceiving others. I _will_ mistrust my senses; because I am sensible they sometimes mislead me. But, on the other hand, I know that they will not always deceive me. I well know, that the eye shews me the sun much smaller than it really is; but experience, which is only the repeated application of the senses, informs me, that objects always appear to diminish, as their distance increases; thus I attain to a certainty, that the sun is much larger than the earth; thus my senses suffice to rectify the hasty judgments, which they themselves had caused. In warning us to mistrust the testimony of our senses, the priests annihilate the proofs of all religion. If men may be dupes of their imagination; if their senses are deceitful, how shall we believe the miracles, which struck the treacherous senses of our ancestors? If my senses are unfaithful guides, I ought not to credit even the miracles wrought before my eyes. 136. You incessantly repeat that _the truths of religion are above reason_. If so, do you not perceive, that these truths are not adapted to reasonable beings? To pretend that reason can deceive us, is to say, that truth can be false; that the useful can be hurtful. Is reason any thing but a knowledge of the useful and true? Besides, as our reason and senses are our only guides in this life, to say they are unfaithful, is to say, that our errors are necessary, our ignorance invincible, and that, without the extreme of injustice, God cannot punish us for following the only guides it was his supreme will to give.
