A fool marvels at rare things, but a wise man at common ones.
We are so busy doing the urgent that we don't have time to do the important.
The demands that a great man makes are on himself; those of a petty man are upon others.
He who merely knows right principles is not equal to him who loves them.
A man who does not forget an agreement is resolved and honorable man.
Because the newer methods of treatment are good, it does not follow that the old ones were bad: for if our honorable and worshipful ancestors had not recovered from their ailments, you and I would not be here today.
