Ray Monk in the New Statesman:
“Thinking in pictures,” Sigmund Freud once wrote, “stands nearer to unconscious processes than does thinking in words, and is unquestionably older than the latter both ontogenetically and phylogenetically.” There is, in other words, something primordial, something foundational, about thinking visually.
Such a view is anathema to many philoso- phers, a good many of whom believe that all thought is propositional, that to think is to use words. For some of the most distinguished philosophers in history, thinking and verbalis- ing were practically the same thing. Bertrand Russell sometimes to his great frustration, was hopeless at visualising and was more or less indifferent to the visual arts. His mental life seemed almost entirely made up of words rather than images. When his friend Rupert Crawshay-Williams once gave him an intelligence test that involved matching increasingly complicated geometrical shapes, Russell did extremely well up to a certain point and then exceptionally badly after that. “What happened?” Crawshay-Williams asked. “I hadn’t got any names for the shapes,” Russell replied.
In this, as in many other respects, Ludwig Wittgenstein was Russell’s opposite. For Wittgenstein, to think, to understand, was first and foremost to picture. In conversation with his friends, he several times referred to himself as a “disciple” or “follower” of Freud and many people since have been extremely puzzled what he might have meant by this. I think Freud’s remark quoted above might provide the key here, that it might have something to do with the emphasis one finds in Freud on the primordiality of “thinking in pictures”.
