and made insignificant in practice, by selecting for study simple kinds of ex- periences which are devoid of emotional content and which can be tested for reliability. A simple somatosensory ''raw feel" fulfills these characteristics (see papers nos. 2,5). In any case, if we fail to find ways to use introspective reports in convincingly acceptable studies we would give up the ability to investigate the relation between conscious experience and neural activity, something warned against by William James (Krech, 1969). Another factor in the dearth of direct experimental studies is, of course,...

I received my first introduction to the brain sciences in 1936 and 1937, for me the second and third years of the 7-year medical school curriculum at the University of Leiden. During those years my interest in the subject was aroused in particular by the brilliant lectures of the physiologist G. C.
