Even though he was a very successful lawyer and great orator, Cicero believed his political career was more important than his other achievements. His political and philosophical writings are still popular. More than fifty judicial speeches have been preserved.
We are slaves of the law in order that we may be able to be free.
Justice is the set and constant purpose which gives every man his due.
The function of wisdom is to discriminate between good and evil.
Justice is the crowning glory of the virtues.
A home without books is a body without soul.
Honor is the reward of virtue.
The budget should be balanced, the Treasury should be refilled, public debt should be reduced, the arrogance of officialdom should be tempered and controlled, and the assistance to foreign lands should be curtailed lest Rome become bankrupt. People must again learn to work, instead of living on public assistance.
It is the nature of every person to error, but only the fool perseveres in error.
There exists a law, not written down anywhere, but inborn in our hearts; a law which comes to us not by training or custom or reading; a law which has come to us not from theory but from practice, not by instruction but by natural intuition. I refer to the law which lays it down that, if our lives are endangered by plots or violence or armed robbers or enemies, any and every method of protecting ourselves is morally right.
Gratitude is not only the greatest of virtues, but the parent of all the others.
The authority of those who teach is often an obstacle to those who want to learn.
The more laws, the less justice.
The universe is transformation; our life is what our thoughts make it.
Nature has planted in our minds an insatiable longing to see the truth.
Before beginning, plan carefully.
Silent leges inter arma. (Laws are silent in times of war.)
