A quote from Karl H Pribram, The Form Within: My Point of View
p. 514 “The revolution in science inaugurated by quantum physics made us aware, as never before, of taking into consideration the role of observation and measurement in the construction of data. A personal experience illuminates the extent of this revolution. Eugene Wigner remarked that in quantum physics we no longer have observables (invariants) but only observations. Tongue in cheek, I asked whether that meant that quantum physics is really psychology, expecting a gruff reply to my sassiness. Instead, Wigner beamed a happy smile of understanding and replied: ‘Yes, yes, that’s exactly correct.’ In a sense, therefore, if one takes the reductive path in science one ends up with psychology, not particles of matter.”
