What have been called the "two distinct frescoes or canti"[4] of Beyond the Pleasure Principle break between sections III and IV. If, as Otto Fenichel remarked, Freud's "new [instinctual] classification has two bases, one speculative, and one clinical",[5] thus far the clinical. In Freud's own words, the second section "is speculation, often far-fetched speculation, which the reader will consider or dismiss according to his individual predilection"[6] — it has been noted that "in Beyond the Pleasure Principle, Freud used that unpromising word "speculations" more than once".[7]
