You might as well take the sun out of the sky as friendship from life: for the immortal gods have given us nothing better or more delightful.
Marcus Tullius CiceroBut if you should take the bond of goodwill out of the universe no house or city could stand, nor would even the tillage of the fields abide. If that statement is not clear, then you may understand how great is the power of friendship and of concord from a consideration of the results of enmity and disagreement. For what house is so strong, or what state so enduring that it cannot be utterly overthrown by animosities and division?
Marcus Tullius CiceroAll literature, all philosophical treatises, all the voices of antiquity are full of examples for imitation, which would all lie unseen in darkness without the light of literature.
Marcus Tullius CiceroThere is a difference between justice and consideration in one's relations to one's fellow men. It is the function of justice not to do wrong to one's fellow men of considerateness, not to wound their feelings.
Marcus Tullius CiceroFor out of such an ungoverned populace one is usually chosen as a leader, someone bold and unscrupulous who curries favor with the people by giving them other men's property. To such a man the protection of public office is given, and continually renewed. He emerges as a tyrant over the very people who raised him to power.
