The professor of neuroscience at Oxford, Colin Blakemore, also praises doubt as the engine of intelligence. He cites the first serious piece of philosophy he ever read, Descartes’ “Discourse on Method”, and its opening line “Good sense is the most evenly shared thing in the world, for each of us thinks he is so well endowed with if that even those who are the hardest to please in all other respects are not in the habit of wanting more than they have.”
And finally, psychotherapist Susie Orbach writes about the importance of self-knowledge. If we know what we feel it means that "we can connect with others from a basis of respect rather than fear, and link with those who feel differently."
