A Ledge Toilet that Demonstrates What Freudian Analysis Was All About

This is not a photograph of
the actual toilet that patients used in Freud's house in Vienna, but it is similar to that one.
Its most conspicuous feature is the ledge where waste matter is deposited for
later examination. When I used the one in Freud's house, not for a solid purpose, I felt I had learned all I needed to know.
