The testimony that the Deity convinces the senses of men of his existence, can only be admitted by us, if our mind considers it less probable that these men should have been deceived, than that the Deity should have appeared to them. Our reason can never admit the testimony of men, who not only declare that they were eye-witnesses of miracles, but that the Deity was irrational; for he commanded that he should be believed, he proposed the highest rewards for faith, eternal punishments for disbelief. We can only command voluntary actions; belief is not an act of volition; the mind is even passive, or involuntarily active: from this it is evident that we have no sufficient testimony, or rather that testimony is insufficient to prove the being of a God.
