While there's life, there's hope.

The nobler a man, the harder it is for him to suspect inferiority in others.

Socrates was the first to call philosophy down from the heavens and to place it in cities, and even to introduce it into homes and compel it to inquire about life and standards and goods and evils.

Other relaxations are peculiar to certain times, places and stages of life, but the study of letters is the nourishment of our youth, and the joy of our old age. They throw an additional splendor on prosperity, and are the resource and consolation of adversity; they delight at home, and are no embarrassment abroad; in short, they are company to us at night, our fellow travelers on a journey, and attendants in our rural recesses.

By doubting we come at truth.

To the sick, while there is life there is hope.

The spirit is the true self.

We should not be so taken up in the search for truth, as to neglect the needful duties of active life; for it is only action that gives a true value and commendation to virtue.

The greater the difficulty, the greater the glory.
