Conscience is a dog that does not stop us from passing but that we cannot prevent from barking.

Men of reason have endured;men of passion have lived.

The person is always happy who is in the presence of something they cannot know in full. A person as advanced far in the study of morals who has mastered the difference between pride and vanity.

To enjoy and give enjoyment, without injury to yourself or others; this is true morality.

And so I leave this world, where the heart must either break or turn to lead (suicide note)

Change, change,--we all covet change.

Education must have two foundations --morality as a support for virtue, prudence as a defense for self against the vices of others. By letting the balance incline to the side of morality, you only make dupes or martyrs; by letting it incline to the other, you make calculating egoists.
