Since this is the first time in these lectures that we speak of the sexual life, I must tell you the manner in which I intend to handle this theme. Psychoanalysis sees no reason for hiding matters or treating them by innuendo, finds no necessity of being ashamed of dealing with this important subject, believes it is proper and decent to call everything by its correct name, and hopes most effectively in this manner to ward off disturbing or salacious thoughts. The fact that I am talking before a mixed audience can make no difference on this point. Just as there is no special knowledge either for the Delphic oracle or for flappers, so the ladies present among you have, by their appearance in this lecture hall, made it clear that they wish to be considered on the same basis as the men. The dream has a number of representations for the male genital that may be called symbolic, and in which the similarity of the comparison is, for the most part, very enlightening. In the first place, the holy figure 3 is a symbolical substitute for the entire male genital. The more conspicuous and more interesting part of the genital to both sexes, the male organ, has symbolical substitute in objects of like form, those which are long and upright, such as _sticks_, _umbrellas_, _poles_, _trees_, etc. It is also symbolized by objects that have the characteristic, in common with it, of penetration into the body and consequent injury, hence pointed _weapons_ of every type, _knives_, _daggers_, _lances_, _swords_, and in the same manner _firearms_, _guns_, _pistols_ and the _revolver_, which is so suitable because of its shape. In the troubled dream of the young girl, pursuit by a man with a knife or a firearm plays a big role. This, probably the most frequent dream symbolism, is easily translatable. Easily comprehensible, too, is the substitution for the male member of objects out of which water flows: _faucets_, _water cans_, _fountains_, as well as its representation by other objects that have the power of elongation, such as _hanging lamps_, _collapsible pencils_, etc. That _pencils_, _quills_, _nail files_, _hammers_ and other _instruments_ are undoubtedly male symbols is a fact connected with a conception of the organ, which likewise is not far to seek.
