“You have seen these things. You know a great deal. And you are not coordinated with the new configuration.”

Philip K. Dick book Adjustment Team

Adjustment Team (1954)
Context: "I get the picture." His voice was almost inaudible. A chilling premonition moved through him. "I was supposed to be changed like the others. But I guess something went wrong."
"Something went wrong. An error occurred. And now a serious problem exists. You have seen these things. You know a great deal. And you are not coordinated with the new configuration."
"Gosh," Ed muttered. "Well, I won't tell anybody." Cold sweat poured off him. "You can count on that. I'm as good as changed."

“The dominant metaphor of conceptual relativism, that of differing points of view, seems to betray an underlying paradox. Different points of view make sense, but only if there is a common co-ordinate system on which to plot them; yet the existence of a common system belies the claim of dramatic incomparability.”

Donald Davidson (philosopher) (1917–2003) scriitor amator

“As is known, scientific physics dates its existence from the discovery of the differential calculus. Only when it was learned how to follow continuously the course of natural events, attempts, to construct by means of abstract conceptions the connection between phenomena, met with success. To do this two things are necessary: First, simple fundamental concepts with which to construct; second, some method by which to deduce, from the simple fundamental laws of the construction which relate to instants of time and points in space, laws for finite intervals and distances, which alone are accessible to observation”

“Space is not the vague and undetermined medium which Kant imagined; if purely and absolutely homogeneous, it would be of no use, and could not be grasped by the mind. Spatial representation consists essentially in a primary coordination of the data of sensuous experience. But this coordination would be impossible if the parts of space were qualitatively equivalent, if they were really interchangeable.”

“For some representations of space the brain typically uses egocentric coordinates (centered on the receiver)… For other behaviors… the brain uses allocentric coordinates”

“I knew that the library was also the materialization of a certain level of the psyche, even as our world is. Only there, time is laid out like space is here. The windows of the library coincide with definite places in our space-time. In our world, these points of intersection may appear as natural objects, and these correlate with coordination points in your psyche. Moving toward these coordination points in your mind automatically lines up your consciousness to some extent with this other reality, and stabilizes conditions enough to allow for more or less conscious entry and return.”

“The point, being indivisible, occupies no space. That which occupies no space is nothing.”

Context: The point, being indivisible, occupies no space. That which occupies no space is nothing. The limiting surface of one thing is the beginning of another.

“Space and time are the framework within which the mind is constrained to construct its experience of reality.”

“Five coordinating mechanisms seem to explain the fundamental ways in which organizations coordinate their work: mutual adjustment, direct supervision, standardization of work processes, standardization of work outputs, and standardization of worker skills.”
