Fortune may rob us of our wealth, not of our courage.

No one can have all he desires.

The good things of prosperity are to be wished; but the good things that belong to adversity are to be admired.

Human society is like an arch, kept from falling by the mutual pressure of its parts

No man can live happily who regards himself alone, who turns everything to his own advantage. Thou must live for another, if thou wishest to live for thyself.

Nature has given us the seeds of knowledge, not knowledge itself.

There is no easy way from the earth to the stars.
