Summary
A symbol is a visible sign of an invisible microcosm, a node in an information web. Symbols form the real stuff of a language with variety provided by differing interpretations. For instance variables, procedures, types, constants, literals, and functions are all symbols. Literals are symbolic constants and expressions, preventing "mystery" numbers. Symbols allow a programmer to re-use other's work without being concerned about implementation. This is a motive behind high-level languages in providing symbolic access to machine operations.

Subtopic: communication as symbolic
Quote: communication requires a predefined mapping of representations into information [»richG9_1975]
| Quote: information in its ordinary sense means something that is communicated by conscious, intentional agents via symbols that have an agreed interpretation [»raatP_1998]
| Subtopic: symbol as innate
Quote: humans spontaneously assign symbols to objects and events; animals do not [»hausMD_2000]
| Quote: humans manipulate symbol sequences to alter their meaning; a combinatoric system not available to animals
| Subtopic: levels of abstraction
Quote: consider this sequence: Godfather, Paris Theater, Paris at 58th and 5th, turn left... [»martJ_1975, OK]
| Subtopic: contextual symbol
Quote: symbols have multiple, complex meanings and denotations, often varying from one context to another [»kentW6_1991]
| Subtopic: symbol as reminder
Quote: man hath set up a visible mark, which when seen again, may bring to mind the original thought; like a rock at sea [»hobbT_1650, OK]
| Quote: names are marks of human voices which recall conceptions of the things named [»hobbT_1650, OK]
| Subtopic: symbol as concept
Quote: a concept is a unit, i.e., it is discrete; e.g., easier to remember discrete relationships than continuous quantities [»sowaJF_1984]
| Quote: combine geometrical analysis with algebra by reducing proportions to simple symbols and relations [»descR_1637]
| Quote: there is nothing universal but names; the things named are not themselves universal [»hobbT_1650, OK]
| Subtopic: symbol as thing
Quote: in ontological symbolism, a symbol refers to an independent object or thing; with operative symbolism (Leibniz), the meaning of symbols is irrelevant to their manipulation [»kramS2_1996]
| Subtopic: word as symbol
Quote: a name is a symbol or combination of symbols by which an entity is known [»senkME1_1973]
| Quote: the classification of ideas is the true basis on which words (the symbols of ideas) should be classified; a basis for the philosophy of language [»rogePM_1853, OK]
| Quote: a symbol or representation is any character string that stands for something, e.g., 'six feet' [»kentW1_1984]
| Subtopic: physical sign as symbol
Quote: a physical thing can refer to another thing or a complex physical situation; acts as a sign [»stamRK7_1985]
| Quote: semiotics starts with the notion of a sign which includes signal or transitory, event-like signs [»stamRK7_1985]
| Subtopic: programming as symbolic
Quote: symbols are everything outside of the system that could have an occurrence inside the system; fixed set, e.g., the English alphabet, 1, x, the American flag [»kentW6_1991]
| Quote: EDSAC assembly routines provided symbolic subroutine calls and symbolic labels; neither was used much [»campM1_1980]
| Quote: use English words to identify subroutines; start with a non-notational character and end with blank tape [»glenAE2_1953]
| Note: a name can be a literal to use, a location to find, a value to track, or a function to execute [»cbb_1990, OK]
| Quote: a file has one, symbolic name that is arbitrarily long and descriptive [»daleRC_1965]
| Quote: a file is a linear array of data accessed by name or by segment number plus offset; independent of device
| Quote: programming languages deal with abstract objects, contrary to the conventional view that programs are symbol strings plus rules for manipulating these strings; the later yields a macrogenerator without regard to semantics [»straC8_1967]
| Subtopic: data as symbol
Quote: resemblance between a database's contents and the original information depends on a common understanding of what references mean [»kentW_1978]
| Quote: some authors equate signs with information, but lose the meaning of that information [»kentW_1978]
