How Quickly All Things Disappear
How quickly all things disappear - in the universe the bodies themselves, but in time the remembrance of them. What is the nature of all sensible things, and particularly those which attract with the bait of pleasure or terrify by pain, or are noised abroad by vapory fame; how worthless, and contemptible, and sordid, and perishable, and dead they are - all this it is the part of the intellectual faculty to observe. To observe too who these are whose opinions and voices give reputation; what death is, and the fact that, if a man looks at it in itself, and by the abstractive power of reflection resolves into their parts all the things which present themselves to the imagination in it, he will then consider it to be nothing else than an operation of nature; and if any one is afraid of an operation of nature, he is a child. This, however, is not only an operation of nature, but it is also a thing which conduces to the purposes of nature.
Marcus Aurelius, in 'Meditations'
