How do we know we are all talking about the same thing? Sometimes my thoughts feel very ‘verbal’, lots of words, and other times I can think through complex things without any words entering my conscious mind at all. And there’s a full continuum between those extremes. Usually it’s somewhere in the middle, and it’s hard to say if I am thinking with an ‘inner voice’ or not. Do others really experience just one extreme or the other, all the time?
