Over these organs—the thyroid, the adrenals,the hypophysis—the contact ceptors have no control. Pro-longed laboratory experimentation seems to prove thispostulate. According to our observations, no amount ofphysical trauma inflicted upon animals will cause hyper-thyroidism or increased adrenalin in the blood, while fearand rage do produce hyperthyroidism and increased ad-renalin (Fig. 44) (Cannon). This is a statement of far-reaching importance and is the key to an explanation ofmany chronic diseases—diseases which are associated withthe intense stimulation of the distance ceptors in humanrelations. Stimuli of the contact ceptors differ from stimuli of thedistance ceptors in still another important particular.

That is, according to phy-logeny and ontogeny this or that sound, this or that smell,this or that sight, through association recapitulates the ex-perience of the species and of the individual—awakens thephylogenetic and ontogenetic memory. In other words,sights, sounds, and odors are symbols which awaken phylo-genetic association. If a species has become adapted tomake a specific response to a certain object, then that re-sponse will occur automatically in an individual of thatspecies when he hears, sees, or sme
