Cicero

Rightly defined philosophy is simply the love of wisdom.

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.

There is pleasure in calm remembrance of a past sorrow.

Rashness belongs to youth; prudence to old age.

No one is so old as to think he cannot live one more year.

The noblest spirit is most strongly attracted by the love of glory.

Orators are most vehement when their cause is weak.

So near is falsehood to truth that a wise man would do well not to trust himself on the narrow edge.

Nothing quite new is perfect.

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.
