Mental Models VII

“It is obvious then, that memory belongs to that part of the soul to which imagination belongs. […] Just as the picture painted on the panel is at once a picture and a portrait, and though one and the same, is both, yet the essence of the two is not the same, and it is possible to think of it both as a picture and as a portrait, so in the same way we must regard the mental picture within us both as an object of contemplation in itself and as a mental picture of something else […]. Insofar as we consider it in relation to something else, e.g. as a likeness, it is also an aid to memory.” (Aristotle, “De Memoria et Reminiscentia” [On Memory and Recollection], 4th century BC)

“In the same way as regards the soul, when that kind of thing in us which mirrors the images of thought and intellect is undisturbed, we see them and know them in a way parallel to sense-perception, along with the prior knowledge that it is intellect and thought that are active. But when this is broken because the harmony of the body is upset, thought and intellect operate without an image, and then intellectual activity takes place without a mind-picture.” (Plotinus, “Enneads”, cca. 270 AD)

“Part of the functions of the imaginative faculty is, as you well know, to retain impressions by the senses, to combine them, and chiefly to form images." (Moses Maimonides, “Guide of the Perplexed”, 1190 [translated by Michael Friedländer, 1904])

”[…] the painter cannot produce any form or figure […] if first this form or figure is not imagined and reduced into a mental image (idea) by the inward wits. And to paint, one needs acute senses and a good imagination with which one can get to know the things one sees in such a way that, once these things are not present anymore and transformed into mental images (fantasmi), they can be presented to the intellect. In the second stage, the intellect by means of its judgement puts these things together and, finally, in the third stage the intellect turns these mental images […] into a finished composition which it afterwards represents in painting by means of its ability to cause movement in the body.” (Romano Alberti, “Della nobiltà della Pittura”, 1585)

“The conception of lines of force was introduced by Faraday to form a mental picture of the processes going on in the electric field. To him these lines were not mere mathematical abstractions. He ascribed to them properties that gave them a real physical significance.” (Hendrik van der Bijl, “The Thermionic Vacuum Tube and Its Applications”, 1920)

“The continuing effects of mental images and ideas that, later, emerge in memory actually take place in the sphere of our feelings. […] Our life of feelings – with its joys, pains, pleasures, displeasures, tensions, and relaxations – is the actual vehicle for the enduring qualities of the ideas and mental images that we can recall at a later stage.” (Rudolf Steiner, “Education for Adolescents”, 1921)

“While the stuff from which our world picture is built is yielded exclusively from the sense organs as organs of the mind, so that every man's world picture is and always remains a construct of his mind and cannot be proved to have any other existence, yet the conscious mind itself remains a stranger within that construct, it has no living space in it, you can spot it nowhere in space.” (Erwin Schrödinger, „Mind and Matter: the Tarner Lectures”, 1956)

“A mental image occurs when a representation of the type created during the initial phases of perception is present but the stimulus is not actually being perceived; such representations preserve the perceptible properties of the stimulus and ultimately give rise to the subjective experience of perception.” (Stephen Kosslyn, “Image and Mind”, 1980)

“[…] a mental model is a mapping from a domain into a mental representation which contains the main characteristics of the domain; a model can be ‘run’ to generate explanations and expectations with respect to potential states. Mental models have been proposed in particular as the kind of knowledge structures that people use to understand a specific domain […]” (Helmut Jungermann, Holger Schütz & Manfred Thuering, “Mental models in risk assessment: Informing people about drugs”, Risk Analysis 8 (1), 1988)

“Mental models are the mechanisms whereby humans are able to generate descriptions of system purpose and form, explanations of system functioning and observed system states, and predictions of future system states.” (William B Rouse & Nancy M Morris, “On looking into the black box: Prospects and limits in the search for mental models”, Psychological Bulletin (3), 1986)
