The organization however is, biologically speaking, artificial and learned. It is no less rigid for that reason. This organizational structure of perception can be broken up, as recent LSD experiments certainly show. This can be dangerous, however. The fact that this does occur shows that the systems of perception are not a part of over-all structure biologically, but learned secondary responses. It is disturbing to the whole organism, however, to break up the strong pattern of usual perception. Inner stability of response is suddenly swept away. Changes that are not yet known occur within the nervous system under these circumstances, both electromagnetic and chemical.
