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.
