2 So even these apparently direct images may have further symbolic residues. One of our earliest experiences was that of being ‘inside’ our mothers, in the (topologically) spherical container that marked the limit of our early worlds. This closed boundary offers an important primitive sense of inside and outside. One universal source for geometry that may be being echoed here (‘mixing memory and desire’, based on ‘lucid souvenirs of the past’) is that of our ante-natal, three-dimensional existence.
In later chapters, I argue that it is for precisely this reason that the metaphor of manipulation has been applied to symbols of various sorts. Symbols can come to act as the ‘manipulatives’ of mathematics, referring at times to the virtual actions of human beings acting as mathematicians at whatever level. 31 3 GEOMETRIC IMAGES AND SYMBOLS What will be the future of the individual imagination in what is usually called the “civilization of the image”? …we run [a danger of] losing a basic human faculty: the power of bringing visions into focus with our eyes shut, of bringing forth forms and colours from the lines of black letters on a white page, and in fact of thinking in terms of images.
They are also heavily conditioned about what is, or is not mathematics. I have to work hard to get them to trust me and sometimes I do not get there. It depends what has gone on before. (Watson, 1991, p. 6 When ‘playing turtle’, children walk through what the screen turtle needs to do in order to achieve the required path. Provided they can attend to their actions while in the midst of carrying them out, they may well be better able to decide what to do next at the keyboard. With all of these physical possibilities, the fact that the ‘object to think with’ is part of the person doing the thinking can provide particularly direct access to the experience.
