M. Brady Brower Libri

In characterizing psychical research as something other than a mere echo of popular spirituality or an anomaly among the sciences, Brower argues that the questions surrounding mediums served to sustain the scientific project by forestalling the establishment of a closed and complete system of knowledge. By acknowledging persistent doubt about the intentions of its participants, psychical research would result in the realization of a subjectivity that was essentially indeterminate and would thus clear the way for the French reception of psychoanalysis and the Freudian unconscious and its more comprehensive account of subjective uncertainty.
