'... How can you imagine anything without using the linguistic signs that make possible the activity we call "imagining"? It should be noted that by "language" I mean anything predicated on the pricipal of difference ...' I hesitate to write this since I must be missing something so obvious as to leave my stupidity naked & vulnerable to the world. Still. What the hell. Everyone knows I'm really, really clever where it really, really, counts. On those days when none of my concubines happen to be available I put myself to sleep with a recurring & deeply satisfying problem: the various mechanical & hydraulic arrangements that could be devised to retract aircraft undercarriages. (And, for once, we can do without the weary contributions from the symbol merchants on the significance of levers & pistons.) The wheels can be retracted outwards & upwards into the wing as in the Spitfire & Me109; or inwards as in the Hurricane; or backwards with a ninety degree rotation as in the Curtis Hawks; or - really brilliantly - with all kinds of kinky wheezes as in, for example, the Grumman Avenger. The positioning of the fulcrum; the mechanical advantages; the forces required, whether mechanical, hydraulic or electrical; how it will all look; & so on. One can consider the possibilities all night long or until sleep intervenes. If I were sufficiently adept at computer graphics I could make a film to demonstrate the various solutions & it would, presumably, be as *satisfyingly real* to a like minded aeroplane-nut as to myself. The 'meaning' would be crystal clear & so far as I can see nothing that any reasonable person could call a linguistic item would be employed. Unless you include the visual images of real items in my head as such. Is that what you mean? What balls. I've obviously get hold of the wrong end of the stick with regard to the word 'language'. Don't cackle too vulgarly. Meanwhile, I shall sit here whistling very loudly, on key & with such panache as to make all my listeners want to dance, the theme & variations from the Trout quintet.
