Wisdom is the only thing which can relieve us from the sway of the passions and the fear of danger, and which can teach us to bear the injuries of fortune itself with moderation, and which shows us all the ways which lead to tranquility and peace.
Not to know what has been transacted in former times is to be always a child. If no use is made of the labors of past ages, the world must remain always in the infancy of knowledge.
We must be ever on the search for some persons whom we shall love and who will love us in return. If good will and affection are taken away, every joy is taken from life.
