 In other words, it is in the controlled conditions of a laboratory that one can, by means of experimenter, experimental subject, and various apparatus, arbitrarily and repeatedly call forth precisely predetermined phenomena of consciousness. The psychologist is not then interested in the psychophysical connections between the somatic or nervous sense-mechanisms and the elicited “inner” phenomena, but solely in describing, “and where possible measuring”, the psychological regularities that such experiments can reveal, viz., regular causal links within the domain of the psychic alone (L III: 165).
