[36] In a recently published study, Jenseits des Lustprinzips (1920) [Beyond the Pleasure Principle, International Psycho-Analytical Library, No. 4], I have attempted to connect the polarity of love and hatred with a hypothetical opposition between instincts of life and death, and to establish the sexual instincts as the purest examples of the former, the instincts of life.

[38] [Literally, 'leaning-up-against type'; from the Greek 'ἁνακλἱνω' 'I lean up against'. In the first phase of their development the sexual instincts have no independent means of finding satisfaction; they do so by propping themselves upon or 'leaning up against' the self-preservative instincts. The individual's first choice of a sexual object is said to be of the 'anaclitic type' when it follows this path; that is, when he choses as his first sexual object the same person who has satisfied his early non-sexual needs. For a full discussion of the anaclitic and narcissistic types of object-choice compare 'Zur Einführung des Narzissmus.—Translator.]
