The life given us, by nature is short; but the memory of a well-spent life is eternal
Roman statesman, orator, lawyer and philosopher, who served as consul in the year 63 BC.
Politicians are not born; they are excreted
While there's life, there's hope
The life of the dead is set in the memory of the living
The authority of those who teach is often an obstacle to those who want to learn
Gratitude is not only the greatest of virtues, but the parent of all others
If we are not ashamed to think it, we should not be ashamed to say it
Nature makes penicillin; I just found it
To conquer oneself is a greater task than conquering others
Simplicity is a matter of taste
You may delay, but time will not
Hell is empty and all the devils are here
The scientific observer of Nature is a kind of mystic seeker in the act of prayer
