The author discusses those patients who continue to act out in spite of an apparent insight into its meaning. It appears that they regard the insight as only half their own; it is also half the analyst's. They react to the interpretations as though they were a disciplinary measure on his part, which they equate with the sort of reasoning of an adult which aids the child's maturity but none the less deprives it of its toy. To understand how insight is unconsciously regarded is important in the therapy not only of 'acting out' cases but probably of 'unanalysable' cases in general. The author notes some similarities and differences between his views and Bergler's in the latter's discussion of the 'cynical phase' which Bergler maintains occurs towards the end of 'progressed cases' (Psa. Rev., 32, 1945).
