It is true that we can get further with explanation than with uninterpreted confession alone, for it at least trains the mind, and therefore may awaken sleeping powers which can intervene in a helpful way. But the fact remains that the most thorough explanation leaves the patient in many cases an intelligent but still incapable child. The trouble is that Freudian explanations in terms of pleasure and its satisfaction are one-sided and therefore insufficient, especially when applied to the later stages of development.
