§4.36.1Θεώρει διηνεκῶς πάντα κατὰ μεταβολὴν γινόμενα καὶ ἐθίζου ἐννοεῖν, ὅτι οὐδὲν οὕτως φιλεῖ ἡ τῶν ὅλων φύσις ὡς τὸ τὰ ὄντα μεταβάλλειν καὶ ποιεῖν νέα ὅμοια.
Constantly observe that all things take place by change, and accustom yourself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.
σπέρμα γὰρ τρόπον τινὰ πᾶν τὸ ὃν τοῦ ἐξ αὐτοῦ ἐσομένου, σὺ δὲ μόνα σπέρματα φαντάζῃ τὰ εἰς γῆν ἣ μήτραν καταβαλλόμενα, τοῦτο δὲ λίαν ἰδιωτικόν.
For everything that exists is, in a manner, the seed of that which will be from it; but you fancy that those only are seeds which are cast into the earth or into a womb, but this is too vulgar.
