" Pessoa could not identify the instruments that he could hear so well, but we can do that for him. There are two groups of instruments in the Pessoa orchestra. First, the main sensory devices with which the world around and inside an organism interacts with the nervous system. Second, the devices that continuously respond emotively to the mental presence of any object or event. The emotive response consists of altering the course of life within the old interior of organisms. The devices are known as drives, motivations, and emotions. "
