Natural historians have always insisted that it is impossible to think of a living creature apart from its environment. Indeed, the two are so intimately joined that it is no easy task to decide, for example, at what stage oxygen from the surrounding air fuses as oxyhemoglobin with the structure of the organism, or when ingested carbohydrate becomes vitalized in the energy productions of muscle. Consequently, the investigation of a human being's constitution must include all the gross and subtle details of his environment—it becomes in effect a study of the "man-environment unit." The problem would perhaps be easier if the palpable universe comprised man's only envelop.
