Thinking and speaking are exactly the same

Muse #383 - in one you speak to yourself

I talk to myself all the time. And when I read this quote by Plato it resonated.

Thinking and spoken discourse are the same thing, except that what we call thinking is, precisely, the inward dialogue carried on by the mind with itself without spoken sound.

— Plato (428 BC - 348 BC) Greek philosopher

Do you do that?
