" If we never describe anything "as it is" but only "as it appears to our minds," we can never have a pure physics, but only neuro-physics — i.e., physics as known through the human nervous system. We can also never have pure philosophy, but only neuro-philosophy — philosophy as known through the human nervous system. And we can never have pure neurology but only neuro-neurology — neurology as known through the human nervous system . . . "
