Edward Weston - Attic

Humans are complicated beings. Contrary to a wall that is to say that exists by the help of very clear directing lines (straight edges, straight angles) that undoubtedly and predictably intersects with other straight lines in a certain and precise point.
On the other hand, a human being is nothing like that. He (she) starts her going on a route so can straight after unpredictably and suddenly turn to another direction.
Also, the human being in general (and here in this picture clearly suggested to me) is crossed by fears, anguishes hence the body position of the subject, turned away from the camera's eye. 
In any case, the human being is not in the least buildings' mathematics.
