To be logical you have to dig up and face your own hidden motives and emotions, and of course they're hidden principally because you don't want to face them. So...um...it's easier to let your basement feelings run the upper storeys, so to speak, and the result is quarrels, love, opinions, anorexia, philanthropy... almost anything you can think of. I just like to know what's going on down there, to pick out why I truly want to do things, that's all. Then I can do them, or not. Whichever.
