"Choose always the way that seems best, however rough it may be, and custom will soon render it easy and agreeable."
"We ought not to quit our post without the permission of Him who commands; the post of man is life."
"No one is free who has not obtained the empire of himself. No man is free who cannot command himself."
"Wealth is a weak anchor, and glory cannot support a man; this is the law of God, that virtue only is firm, and cannot be shaken by a tempest."
"A wound from a tongue is worse than a wound from a sword; for the latter affects only the body, the former the spirit."
"If you have a wounded heart, touch it as little as you would an injured eye. There are only two remedies for the suffering of the soul: hope and patience."
"Choose the life that is best, and constant habit will make it pleasant. [Choose always the way that seems the best, however rough it may be; custom will soon render it easy and agreeable.]"
"It is better either to be silent or to say things of more value than silence. Sooner throw a pearl at hazard than an idle or useless word; and do not say a little in many words but a great deal in a few."
"It is only necessary to make war with five things: with the maladies of the body, the ignorances of the mind, with the passions of the body, with the seditions of the city, and the discord of families."
"The soul of man is divided into three parts, intelligence, reason and passion. Intelligence and passion are possessed by other animals, but reason by man alone... Reason is immortal, all else mortal."

"A conversation should be conducted so that your conversational partners transform themselves from your enemies into your friends and not vice versa."
"A good Soul hath neither too great joy, nor too great sorrow: for it rejoiceth in goodness; and it sorroweth in wickedness. By the means whereof, when it beholdeth all things, and seeth the good and bad so mingled together, it can neither rejoice greatly; nor be grieved with over much sorrow."
"Above and before all things, worship GOD! [Honor first the immortal gods, in the manner prescribed, and respect the oath.] Next, honor the reverent heroes and the spirits of the dead by making the traditional sacrifices. Honor your parents and your relatives. As for others, befriend whoever excels in virtue. Yield to kind words and helpful deeds, and do not hate your friend for a trifling fault as you are able. For ability is near to necessity."
"Above the cloud with its shadow is the star with its light. Above all things reverence thyself."
"As long as Man continues to be the ruthless destroyer of lower living beings, he will never know health or peace. For as long as men massacre animals, they will kill each other. Indeed, he who sows the seed of murder and pain cannot reap joy and love."
"Begin thus from the first act, and proceed; and, in conclusion, at the ill which thou hast done, be troubled, and rejoice for the good."
"By Silence, the discretion of a man is known : and a fool, keeping Silence, seemeth to be wise."
"By the air which I breathe, and by the water which I drink, I will not endure to be blamed on account of this discourse."
