Physiology is a science of bodies. But we cannot understand these unless, in conjunction with them, we understand the body. And for the sake of this conjunction we require perception and sensibility. So the science of bodies nourishes itself, so to speak, through perception and sensation of the body. This perception and sensation will in our present case be verbal and on occasion poetic. It will be artful in terms of poetry. But it will not be literary, because its main reason for being will not reside in itself but in its service to our science, to the knowledge for the sake of our understanding of bodies.
