Sometimes people argue that there are two (or more) equally good ways of looking at the world. So, for example, moral psychologist Haidt argues that the dispute between globalism and parochialism found in the Brexit and Trump movements can be explained by two different personal approaches: liberal and conservative. Liberals are universalistic and optimistic about human nature, conservatives notice the importance of tradition and are pessimistic about human nature. However the notion that there are two equally good fundamental ways of looking at life is an approach found in many popular applications of personality theory.
The problem with this approach is illuminated by the question: from what perspective do we make the statement “There are two equally good ways of looking at the world?”
Is it a conservative point of view? No. is it a liberal point of view? No. It must be a third point of view arrived at by noticing that people have different perspectives. It aspires to be, in other words, the correct point of view.
Either parochialism is correct, or globalism is correct, or a more nuanced view that takes into account when to be parochial and when to be globalist is correct (by the way almost certainly that). However if we are able to form a more nuanced view then we are not divided by our personalities into two groups: the optimists and the pessimists, the universalists and the parochials, the hipsters and the squares. We have the ability to weigh the attractions of both sides and to act.
The view that there are two kinds of people who are equally right is a way of waffling on the issue of how we want to be. Even if there are statistically two kinds of people — racists and non-racists, cruel and kind, brutal and sensitive — we don’t have the option of standing to one side noting the fact. We have to choose one, both or neither, though when we do so we put our souls at peril. Pick hot or cold. The luke-warm gets spat out, including the luke-warmness of noting there are two kinds of people, those who pick hot and those who pick cold.
