🪷On Mind: On Perception (1960-1969)

"Once we give serious consideration to the hypothesis of the unconscious, it follows that our view of the world can be but a provisional one; for if we effect so radical an alteration in the subject of perception and cognition as this dual focus implies, the result must be a world view very different from any known before." (Carl Gustav Jung, "The Structure And Dynamics Of The Psyche", 1960)

"Environments are invisible. Their ground-rules, pervasive structure, and overall patterns elude easy perception." (Marshall McLuhan, "Understanding Media", 1964)

"The direct task of our cognitive apparatus is the formation of invariants, and namely invariants of perception, thinking and motives. […] Still, in the first place, exactly these invariants are, cybernetically speaking, enabling a stabilization of the relationship between humans and their environment and between humans themselves." (Georg Klaus, "Kybernetik und Erkenntnistheorie" ["Cybernetics and Epistemology"], 1966)

"A theory has a physical meaning iff it contains interpretation assumptions that assign physical correlates to its basic concepts. These correlates (referents) need not be and in general are not perceptible. But they must be scrutable, i.e. they must show up as observable effects even if remotely, i. e. at the end of a long chain accounted for by other theories."(Mario Bunge, "Foundations of Physics", 1967)

"Basically, self-regulation requires a functional distinction between perception, decision-making, and action. This is normally achieved by a structural distinction between perceptor elements, control elements and effector elements in the system. Behaviorally, a system may be defined as a “black box” characterized by a given set or range of inputs and outputs. Adequate knowledge of any system requires both structural-functional analysis and behavioral analysis." (Charles R Decher, "The Development of Cybernetics" [in "The Social Impact of Cybernetics", 1967)

"Graphic representation constitutes one of the basic sign-systems conceived by the human mind for the purposes of storing, understanding, and communicating essential information. As a "language" for the eye, graphics benefits from the ubiquitous properties of visual perception. As a monosemic system, it forms the rational part of the world of images. […] Graphics owes its special significance to its double function as a storage mechanism and a research instrument." (Jacques Bertin, Semiology of graphics [Semiologie Graphique], 1967)
