Marcus Aurelius
Meditations 4.48
Think continually how many physicians are dead after often contracting their eyebrows over the sick; and how many astrologers after predicting with great pretensions the deaths of others; and how many philosophers after endless discourses on death or immortality; how many heroes after killing thousands; and how many tyrants who have used their power over men's lives with terrible insolence, as if they were immortal; and how many cities are entirely dead, so to speak, Helice and Pompeii and Herculaneum, and others innumerable. Add to the reckoning all whom thou hast known, one after another. One man after burying another has been laid out dead, and another buries him; and all this in a short time. To conclude, always observe how ephemeral and worthless human things are, and what was yesterday a little mucus, to-morrow will be a mummy or ashes. Pass then through this little space of time conformably to nature, and end thy journey in content, as an olive falls off when it is ripe, blessing nature who produced it, and thanking the tree on which it grew.
Marcus Aurelius, Meditations 4.48, translated by George Long
Cease not to bear in mind how many physicians are dead after puckering up their brows so often over their patients; and how many astrologers after making a great parade of predicting the death of others; and how many philosophers after endless disquisitions on death and immortality; how many great captains after butchering thousands; how many tyrants after exercising with revolting insolence their power of life and death, as though themselves immortal; and how many entire cities are, if I may use the expression, dead, Helice and Pompeii and Herculaneum, and others without number.
Turn also to all, one after another, that come within thine own knowledge. One closed a friend's eyes and was then himself laid out, and the friend who closed his, he too was laid out—and all this in a few short years. In a word, fail not to note how short-lived are all mortal things, and how paltry—yesterday a little mucus, to-morrow a mummy or burnt ash. Pass then through this tiny span of time in accordance with Nature, and come to thy journey's end with a good grace, just as an olive falls when it is fully ripe, praising the earth that bare it and grateful to the tree that gave it growth.
