That the discovery of this great truth, which lies so near and obvious to the mind, should be attained to by the reason of so veryfew, is a sad instance of the stupidity and inattention of men, who, though they are surrounded with such clear manifestations of the Deity, are yet so little affected by them, that they seem as it were blinded with excess of light.
