“Aristotle compared the mind of man to a blank tablet on which nothing was written, but on which all things could be engraved. … There is, however, this difference, that on the tablet the writing is limited by space, while in the case of the mind, you may continually go on writing and engraving without finding any boundary, because, as has already been shown, the mind is without limit.”
Aristoteles hominis animum comparavit tabulae rasae, cui nihil inscriptum sit, inscribi tamen omnia possint. … Hoc interest, quod in tabula lineas ducere non licet, nisi quousque margo permittat: in mente usque et usque scribendo, et sculpendo, terminum nusquam invenies quia (ut ante monitum) interminabilis est.

Cf. Aristotle, De anima, III, 4, 430a: "δυνάμει δ' οὕτως ὥσπερ ἐν γραμματείῳ ᾧ μηθὲν ἐνυπάρχει ἐντελεχείᾳ γεγραμμένον· ὅπερ συμβαίνει ἐπὶ τοῦ νοῦ."
