In conversation, we can hold thoughts and reflect on problems sometimes for hours on end. This is of course why so often, even if we’re trying to figure something out by ourselves, we imagine arguing with or explaining it to someone else. Human thought is inherently dialogic. Ancient philosophers tended to be keenly aware of all this: that’s why, whether they were in China, India or Greece, they tended to write their books in the form of dialogues. Humans were only fully self-conscious when arguing with one another, trying to sway each other’s views, or working out a common problem.
