Oh no worries; I am not trying to pick bones, just offer my perspective (:
I realize you were quoting another source, I just get slightly annoyed by the phrase "writing is thinking" and its various other permutations that come up.
For me, that is very much not the case.
I agree that writing/speech is the normal way to answer a (written/spoken) question. It's how I would clumsily describe my thoughts to someone in that circumstance. But it is not how I would form those thoughts.
Though I have also had conversations with people basically saying they can't imagine thinking without words — the two are one and the same, to them.
I draw and play music too. Sure, in an architecture office, a drawing would be a conventional answer. So would three chords in a rehearsal space.
But in normal circumstances, like these, writing is how we express thoughts. You didn’t respond with a link to SoundCloud or a hosted jpeg.
I get what you are saying. And I am not arguing that writing is the best way of thinking or the only way.
Sorry for not being clear. I was only talking about my thoughts. Not yours.
