The Burden of Understanding. Marcus Aurelius 3.1

Life requires movement, and that is dangerous. We make plans to move, but these plans do not always achieve their ostensible goal; they can become excuses for paralysis, as Marcus recognizes.

Οὐχὶ τοῦτο μόνον δεῖ λογίζεσθαι, ὅτι καθ̓ ἑκάστην ἡμέραν ἀπαναλίσκεται ὁ βίος καὶ μέρος ἔλαττον αὐτοῦ καταλείπεται, ἀλλὰ κἀκεῖνο λογιστέον, ὅτι, εἰ ἐπὶ πλέον βιῴη τις, ἐκεῖνό γε ἄδηλον, εἰ ἐξαρκέσει ὁμοία αὖθις ἡ διάνοια πρὸς τὴν σύνεσιν τῶν πραγμάτων καὶ τῆς θεωρίας τῆς συντεινούσης εἰς τὴν ἐμπειρίαν τῶν τε θείων καὶ τῶν ἀνθρωπείων. ἐὰν γὰρ παραληρεῖν ἄρξηται, τὸ μὲν διαπνεῖσθαι καὶ τρέφεσθαι καὶ φαντάζεσθαι καὶ ὁρμᾶν καὶ ὅσα ἄλλα τοιαῦτα, οὐκ ἐνδεήσει· τὸ δὲ ἑαυτῷ χρῆσθαι καὶ τοὺς τοῦ καθήκοντος ἀριθμοὺς ἀκριβοῦν καὶ τὰ προφαινόμενα διαρθροῦν καὶ περὶ αὐτοῦ τοῦ εἰ ἤδη ἐξακτέον αὑτὸν ἐφιστάνειν καὶ ὅσα τοιαῦτα λογισμοῦ συγγεγυμνασμένου πάνυ χρῄζει, προαποσβέννυται. χρὴ οὖν ἐπείγεσθαι οὐ μόνον τῷ ἐγγυτέρω τοῦ θανάτου ἑκάστοτε γίνεσθαι, ἀλλὰ καὶ διὰ τὸ τὴν ἐννόησιν τῶν πραγμάτων καὶ τὴν παρακολούθησιν προαπολήγειν.

It is not enough merely to reckon with the fact that life consumes itself each day, leaving our share of it that remains always less than it was. We must also confront the limits of our understanding: the more we live, the less we can take for granted our ability to grasp the theory and practice toward which we must orient our minds if we are to accomplish any deed in the realms of gods and men. If we begin a task already raving, we will not lack inspiration, information, imagination, or drive. But if we make good use of ourselves, getting an accurate count of what is required and breaking down what we have already seen, planning how to proceed in the event of our own demise and taking every precaution like a trained operator, then our drive is utterly quenched. Thus, we are pressed not only by the proximity of death, which grows nearer with every event, but also by the burden of our own understanding and awareness, which holds us back from action.
