_I was reading something on the BBC today, regarding the “decoding” by science of people’s “internal voices”. The article was about a new technique, whereby researchers are said to be able to reconstruct words, based on the brain waves of patients thinking of those words. I was reminded of an anecdote about Lacan, one of the most important post-Freudian psychoanalysts.

In 1975, during a lecture tour in the United States, Jacques Lacan spoke at MIT before an audience of mathematicians, linguists, and philosophers. Noam Chomsky, the already famous by then American linguist philosopher and activist, attending the lecture, asked Lacan a question on thought.

Lacan's reply was possibly not what Chomsky expected:

“We think we think with our brains”, Lacan said. “Personally, I think with my feet. That's the only way I really come into contact with anything, solid. I do occasionally think with my forehead, when I bang into something. But I've seen enough electroencephalograms to know there's not the slightest trace of a thought in the brain.”
