The quote is only about the analyst's requirement to be analyzed.
Can anyone provide more input on how far self-analysis can go, analyzing yourself without an analyst? What are the perspectives of Freud and Lacan on this? What's the problematic (self-deception)? Freud was, after all, self-analyzed.
The problem of self-analysis.
There should be a subdivision exploring the problem of self-analysis as the problem of self-deception. There is no guarantee, outside guarantee, that any self-analytical interpretation isn't just a self-deceptive fabrication in servitude to forgetfulness. This is the most interesting question. If I'm analyzing myself, I must split into two instances: the analyzand and the analyst; how and to what degree is such a split possible? How to beat self-deception? Isn't it like playing a game of chess with oneself? What was Lacan's view of it (for instance, he says in Television that without the mere presence of the outside object of the audience, even if an idiotic object, is a guarantee his teaching is not merely self-analysis)... etc.! I'm eager to hear from you that have more knowledge on psychoanalysis on this most interesting topic!
