The idea of reason has at least two main meanings: a rigid, abstract, linear mode, prizing precision and certainty, and owed to the left hemisphere; and an embodied ability to hold in suspension knowledge of various kinds justly, and to evaluate them in the context of lived experience, where reason is not in any sense at war with feeling or imagination. This mode is more dependent on the right hemisphere: and is, like the right hemisphere’s understanding of science, in my view more fruitful than the alternative that is often served up in its place. And it is vanishing and dying.
