The signal to start a love affair is not given by a resounding rendition of the Marseillaise under our new flame's balcony. Neither was Brahms' lullaby played for soldiers charging out of the trenches. Composers of background music for supermarkets or elevators are practicing neuropsychology without knowing it. These are fundamentally cerebral physico-chemical phenomena, triggered by defined frequencies. We do nothing more than this when we transmit pre-recorded molecular activities to biological systems.
Biological systems function like radio sets, by coresonance.
If you tune a receiver to 92.6 Mhz, you tune in Radio-This, because the receiver and the transmitter vibrate at the same frequency. These advances in understanding the inmost mechanism of molecular recognition and signaling do not overturn the science of biology, and even less those of physics and chemistry. We have taken nothing away from classic descriptions, but only taken a step forward by adding to the present body of knowledge. This is the normal course of scientific progress, and there is no reason for it to provoke imprecations and anathema. In deciding that only structures can have an action, biologists find themselves in a pre-Newtonian world where the movement of celestial bodies is described by Ptolemy in terms of epicycles.
