Body and mind: a history and a defense of animism
A 1911 philosophy treatise by psychologist William McDougall, published in New York by Macmillan, arguing for animism and addressing the relation of mind and body. The four pictures are abstract line diagrams: networks of open and filled circles joined by crossing straight lines, a hexagon divided into triangles and labelled a, b, c, d, and a branching fishbone-like figure with circles at its ends. A designer could draw on their geometric node-and-line structure for schematic or systems graphics.
