“One must be prepared to reject not only the schema of the physical library, which is essentially a response to books and their proliferation, but the schema of the book itself, and even that of the printed page as a long term storage device, if one is to discover the kinds of procognitive systems needed in the future.”

As We May Think (1945)
Context: Consider a future device for individual use, which is a sort of mechanized private file and library. It needs a name, and to coin one at random, memex will do. A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory.
It consists of a desk, and while it can presumably be operated from a distance, it is primarily the piece of furniture at which he works. On the top are slanting translucent screens, on which material can be projected for convenient reading. There is a keyboard, and sets of buttons and levers. Otherwise it looks like an ordinary desk.

Context: Mixture of assimilation to earlier schemas and adaptation to the actual conditions of the situation is what defines motor intelligence. But — and this is where rules come into existence — as soon as a balance is established between adaptation and assimilation, the course of conduct adopted becomes crystallized and ritualized. New schemas are even established which the child looks for and retains with care, as though they were obligatory or charged with efficacy.
