you can’t be centered without seeing both sides. mono might work as an audiosignal, but we defintitely need stereo to understand ourselves. though it is not the stereo signal you might think of, not as left – right speakers, but as up and down or dark and light. the duality of things is not an exception but a rule. if you loose any of them out of sight, if you can’t keep them in your field of mental reach, one side will pull you too strong and you spiral out.
