The so-called “semantic nexus” that ties a symbol to what it is supposed to stand for, ceases to function when the symbol user is not able to re-present the symbol’s meaning. Memory, clearly, plays no less a part in the symbolic domain than in that of sensory experience.\nIrrespective of the particular position you may have adopted concerning the foundations of mathematics, you will all agree that symbols such as “+,” “–,” “x,” and “:” refer to operations and can, in fact, be interpreted as imperatives (add!, subtract!, multiply!, divide!). To obey any such imperative, one must not only “know” the operation it refers to, but also how to carry it out; one must know how to re-play the symbolized operation with whatever material happens to be at hand. That is to say, if operator-signs are to function as symbols, the operations to which they refer must have been abstracted by the symbol user from the sensory-motor material with which they were implemented in that symbol user’s own prior experience. (There are, of course, several levels of abstraction, but at the bottom there has to be sensory-motor material.)","highlights":Ӷ^"jQuery321059548330513534732":^°°,^"jQuery321059548330513534732":^°°Ӻ,"text":"","order":"mw-content-text","category":"Argumentation2","data_creacio":1564145965133°
