This is an excellent article by Maria Popova, creator of the wonderful Brain Pickings website, on one of the seminal thinkers in the world of dialogue, the late quantum physicist David Bohm. Already famous as a physicist, admired by the likes of Albert Einstein, Bohm later in life became fascinated with the intertwined subjects of thought and dialogue. His seminal work on the subject is On Dialogue.
Popova’s own commentary in this article is also noteworthy. One of the most profound and least understood aspects and benefits of genuine dialogue is highlighted in this article: how authentic dialogue opens the possibility of something new and unexpected arising from the interaction.
