The aim of this brief work is to bring together the doctrines of psycho-analysis and to state them, as it were, dogmatically-in the most concise form and in the most positive terms. Its intention is naturally not to compel belief or to establish conviction. The teachings of psycho-analysis are based upon an incalculable number of observations and experiences, and no one who has not repeated those observations upon himself or upon others is in a position to arrive at an independent judgement of it.
