Abstract

The standard account of arousal seems on the surface relatively straight forward. Its basic meaning is to awaken someone, reading him for activity. Physiologically, this involves stimulating the cerebral cortex into a general state of wakefulness and attention. The aroused subject shows an increased heart rate and blood pressure. Psychologically, sensory alertness, mobility and readiness to respond all mark the aroused state. As all the experts agree, arousal involves more than the simple presence of an external stimulation. It requires impulses that are external and internal to the body. To be effective, the external impulses must find a corresponding response. Thus, it is no good trying to wake someone up by a sound outside of the range of his hearing. Similarly, the genital displays of one species will not cause sexual arousal in another. In neither case, can the external impulses activate the inner impulses or drives. This requires the presence of appropriate stimuli. Thus, the sight and smell of food arouses appetite. It awakens the drive of hunger, which is directed towards the food. Similarly, the sight, odor and touch of the sexual partner brings about sexual arousal and activation of the corresponding sexual drive. Even in the case of arousal from sleep by such varied stimuli as a light being turned on, a noise, or the touch of a person fit into the pattern of an inner impulse or drive being activated by an external impulse. The drive in this case is towards the various stimuli that our senses prime us to receive. Our need for such is as basic as that for food. Placed in a situation of sensory deprivation, the mind attempts to make up their loss by generating hallucinations. The German phenomenologist, Edmund Husserl, spoke in this context of “non-objectifying instincts.” They designate an instinctive “interest in the data and fields of sensation—before the objectification of sense data,” that is, before there is “a thematically actualizable object” for the drive to fasten on.[i] In each of these examples, hunger, sex, or simple sensation, the external stimuli trigger internal processes primed to response..
