Adapting critical methods from such wide-ranging fields as anthropology, linguistics, philosophy, biology, and other sciences, Schapiro appraises fundamental semantic terms such as "organic style," "pictorial style", "field and vehicle," and "form and content"; he elucidates eclipsed intent in a well-known text by Freud on Leonardo da Vinci, in another by Heidegger on Vincent van Gogh.

In His first essay, The Unity of Picasso's Art, Schapiro dismantles this apparent paradox by finding unity through hidden associations among seemingly disparate works and unsuspected ties to Picasso's personal experiences.".
