“The most important factor in every function is: ‘Is it under our control or not?’ So when imagination is under our control we do not even call it imagination; we call it by various names—visualization, creative thinking, inventive thinking—you can find a name for each special case. But when it comes by itself and controls us so that we are in its power, then we call it imagination. Again, there is another side of imagination which we miss in ordinary understanding. This is that we imagine non-existent things—non-existent capacities, for instance. We ascribe to ourselves powers which we do not have; we imagine ourselves to be self-conscious although we are not. We have imaginary powers and imaginary self-consciousness and we imagine ourselves to be one, when really we are many different ‘I’s. There are many such things that we imagine about ourselves and other people. For instance, we imagine that we can ‘do’, that we have choice; we have no choice, we cannot ‘do’, things just happen to us.”
