Meditations 7.49

Consider the past,—such great changes of political supremacies; thou mayest foresee also the things which will be. For they will certainly be of like form, and it is not possible that they should deviate from the order of the things which take place now; accordingly to have contemplated human life for forty years is the same as to have contemplated it for ten thousand years. For what more wilt thou see?

Marcus Aurelius, Meditations 7.49, translated by George Long

Pass in review the far-off things of the past and its succession of sovranties without number. Thou canst look forward and see the future also. For it will most surely be of the same character, and it cannot but carry on the rhythm of existing things. Consequently it is all one, whether we witness human life for forty years or ten thousand. For what more shalt thou see?

Marcus Aurelius, Meditations 7.49, translated by C. R. Haines
