Phrenology is the practice of feeling around for bumps on the head, lumps which explain why Rhinos act as We do. The process is fun, since We don’t know what We might find. Rhinos all have lumps here and there, but if they indicate something beside clumsiness, who could tell Us what?
We do not know, but We still pat our heads. When it occurs to Us.
We may not know Today what is going on, Phrenologically, but who can say about tomorrow? Right. Nobody.
