“I shall try to show that there is a comprehensible transition from the sane schizoid way of being-in-the-world to a psychotic way of being-in-the-world.”

Context: Existential phenomenology attempts to characterize the nature of a person's experience of his world and himself. It is not so much an attempt to describe particular objects of his experience as to set all particular experiences within the context of his whole being-in-his-world. The mad things said and done by the schizophrenic will remain essentially a closed book if one does not understand their existential context. In describing one way of going mad, I shall try to show that there is a comprehensible transition from the sane schizoid way of being-in-the-world to a psychotic way of being-in-the-world. Although retaining the terms schizoid and schizophrenic for the sane and psychotic positions respectively, I shall not, of course, be using these terms in their usual clinical psychiatric frame of reference, but phenomenologically and existentially.

This quote is often attributed to William Penn, but there are no records of it before the 19th century, and its actual source seems to have most likely been another prominent Quaker, Stephen Grellet.

Context: The Western World has been brainwashed by Aristotle for the last 2,500 years. The unconscious, not quite articulate, belief of most Occidentals is that there is one map which adequately represents reality. By sheer good luck, every Occidental thinks he or she has the map that fits. Guerrilla ontology, to me, involves shaking up that certainty. I use what in modern physics is called the "multi-model" approach, which is the idea that there is more than one model to cover a given set of facts. As I've said, novel writing involves learning to think like other people. My novels are written so as to force the reader to see things through different reality grids rather than through a single grid. It's important to abolish the unconscious dogmatism that makes people think their way of looking at reality is the only sane way of viewing the world. My goal is to try to get people into a state of generalized agnosticism, not agnosticism about God alone, but agnosticism about everything. If one can only see things according to one's own belief system, one is destined to become virtually deaf, dumb, and blind. It's only possible to see people when one is able to see the world as others see it. That's what guerrilla ontology is — breaking down this one-model view and giving people a multi-model perspective.
