Ernest Jones considers Freud's claim on Eitingon "a rather curious request ... [perhaps] an inner denial of his novel thoughts about death having been influenced by his depression over losing his daughter".[34] Others have also wondered about "inventing a so-called death instinct — is this not one way of theorising, that is, disposing of — by means of a theory — a feeling of the "demoniac" in life itself ... exacerbated by the unexpected death of Freud's daughter"?[35] — and it is certainly striking that "the term 'death drive' — Todestrieb — entered his correspondence a week after Sophie Halberstadt's death"; so that we may well accept at the very least that the "loss can claim a subsidiary role ... [in]his analytic preoccupation with destructiveness".[36]
