But Opinion is the complication of memory and sensation. For when we meet for the first time with a thing perceptible by a sense, and a sensation is produced in us by it, and from this sensation Memory, and we subsequently meet again with the same thing perceived by a sense, we combine the memory previously brought into action with the sensation produced a second time... And when these, placed along each other, agree, a true opinion is produced; but when they swerve from each other, a false one... Now Cogitation is an operation of the mind, while contemplating the first things perceptible by mind. And this seems to be twofold; one, while it was contemplating things perceptible by mind, previous to the soul existing in the body ; another, after it had been compelled to come into this body. Of these, one [that contemplated previous to the soul existing in the body] was called Cogitation ; but after it existed in the body, that, which was then called Cogitation, was now called Physical Thinking, as being a cogitation in a subjective soul... Now Physical Thinking is called by him (Plato) both a simple science, and a fledging of the soul; and sometimes, recollection. — Alcinous, *Handbook*, Ch. 4, trans. George Burges (1854) **Surface Gloss:** Opinion is formed by matching a fresh sense-impression against a stored memory-stamp; misalignment causes error. Meanwhile, our pre-natal direct vision of the Ideas ("Cogitation") survives inside the embodied soul as innate concepts ("Physical Thinking" or recollection), which judge sensory life. Error in daily judgment rarely comes from raw data alone; it comes from the *overlay* ("complication") of a fresh observation onto an old mental template that only superficially matches it. To audit your judgments, separate the raw incoming signal from the stored memory-stamp you are snapping it onto. Simultaneously, recognize that you cannot evaluate empirical data without prior, non-empirical standards of value ("natural notions") that serve as your baseline rulers.

[Why it matters]

Opinion is formed by matching a fresh sense-impression against a stored memory-stamp; misalignment causes error. Meanwhile, our pre-natal direct vision of the Ideas ("Cogitation") survives inside the embodied soul as innate concepts ("Physical Thinking" or recollection), which judge sensory life. Alcinous solves the problem of how an embodied human bridges the gap between fluctuating sensory data and unchanging scientific truth by constructing a dual-track cognitive mechanics. On the lower track (Opinion), the body’s sense organs strike the soul, leaving a permanent trace (Memory) like a signet ring on wax. When a second sensation occurs, the soul overlays the new perception onto the stored memory-trace. If they align, true opinion results; if they slip sideways—like mistaking Plato for Socrates down the street—falsehood occurs. On the upper track (Science), the soul possesses *Physical Thinking* (innate natural notions). Before entering a body, the soul exercised pure *Cogitation*, gazing directly at the primary Ideas. Once incarnated, that pre-natal vision remains latent in the soul as stored standards of beauty, goodness, and essence. Scientific reasoning is built by awakening these dormant, pre-embodied standards ("fledging the soul"). **[INTERPRETATION: PRISCA THEOLOGIA / ESOTERIC]** Burges (1854) points out in his footnotes that Ficino translates the soul's entry into the body as *"in corpus hoc mersa est"* ("plunged/submerged into this body"), reading *embebusthai* rather than simply "compelled to come." In the esoteric reception of the Renaissance, this cognitive model is the key to the doctrine of the *scintilla* or buried divine spark. The human mind is not a blank slate waiting for sensory inscription; it is a drowned divinity carrying the complete blueprint of the intelligible cosmos sealed within its memory. Ficino links Alcinous’s "fledging of the soul" (*alatio anime*) to the awakening of the innate *notiones communes* through contemplative discipline. While the lower imagination (*phantasia*) paints fleeting portraits out of waxen sense-impressions, the awakened philosopher uses those outer images merely as talismanic triggers to unseal the pre-natal vision of the Ideas acquired before the soul's descent through the planetary spheres.
