Locke preached the sermon which every generation learns with such difficulty and forgets with such ease: “We should do well to commiserate our mutual ignorance, and endeavor to remove it in all the gentle and fair ways of information, and not instantly treat others ill, as obstinate and perverse, because they will not renounce their own, and receive our opinions. . . . For where is the man that has incontestable evidence of the truth of all that he holds, or of the falsehood of all he condemns?”
