The glory of saving a country is not for him who has contributed to its ruin.

To be happy does not mean to indulge in foolishness!

Genius has no country. It blossoms everywhere. Genius is like the light, the air. It is the heritage of all.

Man works for an object. Remove that object and you reduce him into inaction.

Travel is a caprice in childhood, a passion in youth, a necessity in manhood, and an elegy in old age.

He who does not know how to look back at where he came from will never get to his destination.

Treat your old parents as you would like to be treated by your children later.
