As regards the much-discussed _symbolism_ of dreams, the value attached to it varies according to whether the standpoint of causality or of finality is adopted. According to Freud's causal view point it proceeds from a _craving_, viz. from the suppressed dream-wish. This craving is always somewhat simple and primitive, and is able to disguise itself under manifold forms. For instance, the young man in question might just as well have dreamt that he had to open a door with a key, or that he had to travel by aeroplane, or that he was kissing his mother, etc. From this standpoint all those things would have had the same meaning. In this way, the typical adherents of Freud's school have come to the point of interpreting--to give a gross instance--almost all long objects in dreams as phallic symbols. From the view-point of finality, the various dream pictures have each their own peculiar value. For instance, if the young man, instead of dreaming of the apple scene, had dreamt he had to open a door with a key, the altered dream picture would have furnished associative material of an essentially different character; that, again, would have resulted in the conscious situation being supplemented by associations of a totally different kind from those connected with the apple scene. From this point of view, it is the diversity of the dream's mode of expression that is full of meaning, and not the uniformity in its significance. The causal view-point tends by its very nature towards uniformity of meaning, that is, towards a fixed significance of symbols. On the other hand, the final view-point perceives in an altered dream picture, the expression of an altered psychological situation. It recognises no fixed meaning of symbols. From this standpoint all the dream pictures are important in themselves, each one having a special significance of its own, to which it owes its inclusion in the dream. Keeping to our previous example, we see that from the standpoint of finality the symbol in this dream is approximately equivalent to a parable; it does not conceal, but it teaches. The apple scene recalls vividly the sense of guilt, at the same time disguising the real deed of our first parents.
