In order to do good, a man must be good; and he will not be good except he have instruction by counsel and by example.

Man is not made better by being degraded; he is seldom restrained from crime by harsh measures, except the principle of fear predominates in his character, and then he is never made radically better for its influence.

The fact is that, in all prisons everywhere, cruelties on the one hand and injudicious laxity of discipline on the other have at times appeared and will, at intervals, be renewed except the most vigilant oversight is maintained.

A man usually values that most for which he has labored; he uses that most frugally which he has toiled hour by hour and day by day to acquire.

Men need knowledge in order to overpower their passions and master their prejudices.

No blessing, no good, can follow in the path trodden by slavery.
