“Let no one delay the study of philosophy while young nor weary of it when old.”

“It is not the pretended but the real pursuit of philosophy that is needed for we do not need the appearance of good health but to enjoy it in truth.”

“The gods can either take away evil from the world and will not, or, being willing to do so cannot; or they neither can nor will, or lastly, they are able and willing.If they have the will to remove evil and cannot, then they are not omnipotent. If they can but will not, then they are not benevolent. If they are neither able nor willing, they are neither omnipotent nor benevolent.Lastly, if they are both able and willing to annihilate evil, why does it exist?”

“He who says either that the time for philosophy has not yet come or that it has passed is like someone who says that the time for happiness has not yet come or that it has passed.”

“He who has peace of mind disturbs neither himself nor another.”

“Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?”

“Accustom yourself to the belief that death is of no concern to us, since all good and evil lie in sensation and sensation ends with death. Therefore the true belief that death is nothing to us makes a mortal life happy, not by adding to it an infinite time, but by taking away the desire for immortality. For there is no reason why the man who is thoroughly assured that there is nothing to fear in death should find anything to fear in life. So, too, he is foolish who says that he fears death, not because it will be painful when it comes, but because the anticipation of it is painful; for that which is no burden when it is present gives pain to no purpose when it is anticipated. Death, the most dreaded of evils, is therefore of no concern to us; for while we exist death is not present, and when death is present we no longer exist. It is therefore nothing either to the living or to the dead since it is not present to the living, and the dead no longer are.”
