10 ;;Quote: the intension of a word is meaning in semantic memory while its extension is the corresponding set of things

12 ;;Quote: an analytic statement follows from intensions; a synthetic statement is verified with extensions

13 ;;Quote: databases use extension (database entities) and intension (database constraints)

13+;;Quote: a statement about a database is analytic if it follows from constraints and synthetic if need to query the database

13 ;;Quote: Aristotle defined categories for the primitive concepts (e.g., relation, time); build concepts from general type (genus) and differentia

13+;;Quote: the intension of a complex concept may be defined by more primitive concepts

14 ;;Quote: reductionism started by Lull in 13c; defined by Leibniz in his Universal Characteristic

14+;;Quote: Leibniz represented primitives as primes and other concepts by their products; universal dictionary for mapping concepts to numbers

14+;;Quote: Leibniz invented first calculating machine; for manipulating concepts

15 ;;Quote: Wittgenstein--ordinary words like game have no common properties; instead games share a family resemblance

15+;;Quote: Wittgenstein--meaning of a word is its use in the language

27 ;;Quote: an icon is a temporary record of sensory input that lasts 1/4 second; e.g., movies and holding words across eye fixations

28 ;;Quote: a visual schema is a pattern of percepts from previous experience that are used to build models for interpreting new experience

28 ;;Quote: before the discovery of chromosomes, they did not appear in published drawings of cell nuclei

28 ;;Quote: hearing and touch also rely on percepts and icons (8 seconds and 20 seconds resp.); none for olfaction

31 ;;Quote: the brain searches percepts for ones that match parts of a new sensory icon

38 ;;Quote: thoughts without symbols fly away in the wind

38 ;;Quote: conceptual graphs are a universal, language-independent deep structure; a concept is a node of the graph, a unit of knowledge

39 ;;Quote: a concept is a unit, i.e., it is discrete; e.g., easier to remember discrete relationships than continuous quantities

40 ;;Quote: speech has a continuous range of dynamics for expressing emotions (also primates)

40+;;Quote: speech uses discrete words or morphemes for expressing concepts

41 ;;Quote: emotional words and words for value judgments change rapidly in a language

42 ;;Quote: AI concentrates on discrete aspects of intelligence while AI critics concentrate on the continuous aspects

45 ;;Quote: a master chess player has between 25,000 and 100,000 schemata; similar to an educated person's vocabulary

45 ;;Quote: a game is an artificial realization of what language offers in a natural form

48 ;;Quote: oral poetry is like a second grammar that operates with the primary grammar of a language

53 ;;Quote: short-term memory may hold pointers to previously stored memories; can not hold unencoded images

61 ;;Quote: Mozart saw all of piece at a single glance, like a beautiful painting; heard all at once

85 ;;Quote: all human languages distinguish proper names from common nouns; names learned very quickly; fundamental to identification

138 ;;Quote: Pierce--existential graphs, e.g., negation as a cut in a sheet of assertion; like Brown's Laws of Form

181 ;;Quote: a model theory should permit incomplete and inconsistent worlds; need to localize inconsistencies

217 ;;Quote: every human language standardizes on a few dozen phonemes even though humans can produce an infinity of sounds

217 ;;Quote: phonemes form a highly structured system; if one is lost in a dialect, all the others are shifted

217 ;;Quote: an exhaustive classification is impossible; always new, unanticipated concepts

271 ;;Quote: a few dozen analogies account for most of the metaphors in everyday speech

278 ;;Quote: with conventional programming, every new fact requires a change in the program; e.g., the post office changing the ZIP code length

288 ;;Quote: keyword searches both preferred and performed better than a menu system based on Dewey Decimal numbers

345 ;;Quote: concepts can accurately represent man-made structures that originated as concepts; e.g., chess

345 ;;Quote: since the world is a continuum, a network of concepts is at best a workable approximation

356 ;;Quote: mental concepts are not definable in neural terms; totally different systems of description
