Not to live as if you had endless years ahead of you. Death overshadows you. While you're alive and able—be good. Book IV

“Neither the uneducated and uninformed of the truth, nor yet those who never make an end of their education, will be able ministers of State; not the former, because they have no single aim of duty which is the rule of all their actions, private as well as public; nor the latter, because they will not act at all except upon compulsion, fancying that they are already dwelling apart in the islands of the blest.” Republic

I hear the ruin of all space, shattered glass and toppled masonry, and time one livid final flame. Ulysses

“let us thank God for having made us this gift of death, so that life is to have meaning; of night, that day is to have meaning; silence, that speech is to have meaning; illness, that health is to have meaning; war, that peace is to have meaning. Let us give thanks to Him for having given us weariness and pain, so that rest and joy are to have meaning. Let us give thanks to him, whose wisdom is infinite.” Leo Africanus
