Fire may symbolize activities deriving from various levels of libidinal and aggressive development. In this paper the oral roots of certain significances of the symbol, fire, are demonstrated. Fire may symbolize active and passive libidinal and aggressive oral wishes. The passive oral wish to be devoured or the wish actively to devour may become manifest through various symbolic representations of the teeth. Specific suicidal fantasies centering about the idea of being crushed may represent concrete manifestations of a primitive oral wish to be reunited in sleep and death with the mother in a fantasy of being eaten, swallowed, and incorporated.
