The basic idea is that cognitive activities are ultimately just activi — Paul Churchland

"The curiosity of Man, and the cunning of his reason, have revealed much of what Nature held hidden."

"Seeing our common-sense conceptual framework for mental phenomena as a theory brings a simple and unifying organization to most of the major topics in the philosophy of mind."

"We do have an organ for understanding and recognizing moral facts. It is called the brain."

"How such an elaborate theory could have become so widely accepted – on the basis of no systematic evidence or critical experiments, and in the face of chronic failures of therapeutic intervention in all of the major classes of mental illness... – is something that sociologists of science and popular culture have yet to fully explain."

"Eliminative materialism is the thesis that our common sense conception of psychological phenomena constitutes a radically false theory, a theory so fundamentally defective that both the principles and ontology of that theory will eventually be displaced, rather than smoothly reduced, by completed neuroscience."

"Your brain is far too complex and mercurial for its behavior to be predicted in any but the broadest outlines or for any but the shortest distances in the future."
