Donal asks: 1. Can a person imagine '2+2=4'? 2. Can a person imagine '2+2=5'? _____ Do you mean "imagine" particular examples or the generic math? Or the math itself? It's easy to imagine two couples meeting at a coffee shop to hold court at a table of four. It's also easy to imagine this same group nine months later, one couple with a newborn child. On the other hand, arithmetic itself resists visualization. To imagine the arithmetic itself, one may have to visualize the numbers on a blackboard--even though that image is only another particular example of the math. ------------------------------------------------------------------ To change your Lit-Ideas settings (subscribe/unsub, vacation on/off, digest on/off), visit www.andreas.com/faq-lit-ideas.html
