Meaning
Memory preserves what was received; agnoscere is recognizing it again. Mos is settled character or habitual manner, not merely a single custom. The repeated idem/eadem insist on sameness of will, character, opinion, knowledge and retained images, while the later reply distinguishes sameness from resemblance.
Use in the book
The question of memory emerges from the hypothesis that a bodily soul is nourished and continually replaced like flesh. VI.13.5 asks how a newly arrived soul would agree with its predecessor. The next unit gives that question concrete contents: the same will, character, opinion, knowledge and memory. Recognition after ten years requires images once received to remain available, and Ficino asks who preserves them if not the same animus that received and judged them. “How can it preserve them if it is not preserved?” makes the identity of the retaining subject central, not only the similarity of successive representations.
This is not an assertion that every mental state remains unchanged. The text qualifies ordinary persistence with in plerisque, and elsewhere in Book VI the same soul receives contrary opinions and affections and reasons successively. What persists is the subject capable of changing and retaining, not an absolutely frozen list of thoughts. The appeal to recognition is sharper than merely noting similar behaviour: a current encounter is recognized as one formerly experienced and judged. A successor resembling the earlier subject would still need an account of that relation to the past.
An opponent might nevertheless give the supposed soul-body a long enough material life. VI.13.7 answers by holding the original corporealist theory to its own requirements. To penetrate the organs and explain agility, it proposed an exceptionally subtle body. On Ficino’s historical physics such matter would be especially unstable under the changing heavens, outlasted by bones and sinews and even by rapidly renewed flesh. It would vanish like breath and preserve knowledge for less than a day. The physical premises should remain attributed: this is an internal challenge to the hypothetical subtle substance, not an experimental finding in contemporary neuroscience.
The stronger objection in VI.13.9 appeals to the persistence of bodily form through material turnover. Why could an organized pattern of cognition not similarly survive replacement? Ficino distinguishes exact numerical identity from the successive making of figures resembling one another in some measure. Reproduced likeness then requires a stable source carrying the formative patterns and seeds. The face over a river makes that dependence visible: the waves and reflections are new, but the face producing them remains. Ficino identifies the stable bodily craftsman with soul. If soul also flows, the account loses both the continuing bearer and the continuing producer needed for the resemblance.
VI.13.11 tests three alternatives rather than simply repeating the need for stability. The same quality cannot migrate numerically from an old subject into a new one. A perishing soul cannot fashion a similar image in its successor because effective formation requires a complete agent. A newly coming-to-be soul likewise cannot form itself while incomplete. Thus transfer, copying and self-formation fail for different stated reasons. The memory argument’s conclusion depends on these metaphysical premises about subjects and adequate agents as well as on ordinary long-term recognition. Keeping them explicit reveals the full reasoning without promoting it into a theory of modern information storage or deriving any judgement about a person’s worth from the strength of their memory.

Translation in this edition
The repeated sameness language is intentional and should not be varied away into “similar.” The edition’s “in most people” preserves in plerisque. No claim about the mental abilities of people with different memory capacities should be inferred from this metaphysical reductio.
animus
animus. Printed forms: animi; animis; animo; Animo; animum; Animus; animus.
Mind, often the rational soul considered in its understanding, willing and individual identity. The return-to-God argument preserves mind as mind; the final conversion argument similarly protects rational identity rather than mere survival of some substance. References: V.11.6, V.15.19, V.15.20, V.15.21. See Rational soul and irrational life.
Soul or mind, with local emphasis on inward rational identity rather than a different physical constituent. The rational soul’s location, self-discovery and enduring memory are often expressed through animus; local sense determines whether English uses mind or soul. References: VI.1.1, VI.2.9, VI.2.23, VI.13.6. See Persistence, memory and recognition.
Soul or mind with emphasis on inward cognitive and affective life. The food argument concerns its desire, intellectual strengthening and distinction from bodily growth; no rigid opposition to anima is imposed here. References: VIII.2.1, VIII.2.3, VIII.2.5, VIII.2.8. See Food, truth, and the hungry mind.
flatus; evanescere
flatus; evanescere. Printed forms: evanescens; flatus alicuius instar.
Like a breath; vanishing. The image makes the materialist soul too unstable to retain knowledge even for a day. References: VI.13.7. See Persistence, memory and recognition.
incolumis; servare
incolumis; servare. Printed forms: incolumes; servat; servatur; serventur.
Intact; to preserve and be preserved. Ficino asks how retained contents persist if the retaining subject does not itself remain. References: VI.13.6. See Persistence, memory and recognition.
manere; permanere; constare
manere; permanere; constare. Printed forms: constabit; constare; constat; constet; maneat; manere; manet; permanebunt; permanere; permanet.
To remain or persist; to stand established, consist, or be evident, according to construction. Persistence of the knowing subject differs from constare used for an inference being established or a body consisting of constituents. References: VI.1.2, VI.1.6, VI.4.5, VI.7.3, VI.8.2, VI.13.6, VI.13.7, VI.13.9. See Persistence, memory and recognition.
memoria; agnoscere
memoria; agnoscere. Printed forms: agnoscimus; decennium; memoria.
Memory and recognition after ten years. The temporal example requires a preserver identical with the knower that formerly received and judged the image. References: VI.13.6. See Persistence, memory and recognition.
ossa; nervi; caro
ossa; nervi; caro. Printed forms: caro; ossa et nervi.
Bones, sinews and flesh. In the historical physical comparison these endure longer than a supposed exceptionally subtle soul-body. References: VI.13.7. See Persistence, memory and recognition.
renovare; labi
renovare; labi. Printed forms: labitur; renovatur.
To be renewed and slip away. Daily bodily renewal is the proposed model whose inadequacy for enduring personal cognition the chapter tests. References: VI.13.7. See Persistence, memory and recognition.
voluntas; mos; opinio; scientia
voluntas; mos; opinio; scientia. Printed forms: Idem mos; opinio eadem et scientia; voluntas eadem.
Same will, character, opinion and knowledge. The coordinated list supplies several kinds of continuity that a changing-substance account must explain. References: VI.13.6. See Persistence, memory and recognition.
