“All philosophies are mental fabrications. There has never been a single doctrine by which one could enter the true essence of things.”

“The sole philosophy open to those who doubt the possibility of truth is absolute silence -- even mental.”

“Philosophy, art, and science are not the mental objects of an objectified brain but the three aspects under which the brain becomes subject.”

“We may say, in a broad way, that Greek philosophy down to Aristotle expresses the mentality appropriate to the City State; that Stoicism is appropriate to a cosmopolitan despotism; that stochastic philosophy is an intellectual expression of the Church as an organization; that philosophy since Descartes, or at any rate since Locke, tends to embody the prejudices of the commercial middle class; and that Marxism and Fascism are the philosophies appropriate to the modern industrial state.”

“No conceptually regimented and normatively informed theory of mental disorder can be devised without taking philosophy of mind seriously and knowing something about this subject area of philosophy and of such topics as consciousness, Intentionality, personal identity, the mind/body problem and rationality.”
