“The power of ‘the Eye of the Heart,’ which produces insight, is vastly superior to the power of thought, which produces opinions,” the great British economic theorist and philosopher E.F. Schumacher wrote in his 1973 meditation on how we know what we know. He was responding to the Persian poet and philosopher Rumi who, seven centuries earlier, extolled “the eye of the heart” as seventy-fold more seeing than the “sensible eyes” of the intellect. To the intellectually ambitious, this might sound like a squishy notion — or a line best left to The Little Prince. But as contemporary scientists continue to shed light on how our emotions affect our susceptibility to disease, it is becoming increasingly clear that our emotional lives are equipped with a special and non-negligible kind of bodily and cognitive intelligence.

The nature of that intelligence and how we can harness its power is what Martha Nussbaum, whom I continue to consider the most compelling and effective philosopher of our time, examines in her magnificent 2001 book Upheavals of Thought: The Intelligence of Emotions (public library). Titled after Proust’s conception of the emotions as “geologic upheavals of thought,” Nussbaum’s treatise offers a lucid counterpoint to the old idea that our emotions are merely animal energies or primal impulses wholly separate from our cognition. Instead, she argues that they are a centerpiece of moral philosophy and that any substantive theory of ethics necessitates a substantive understanding of the emotions.

Nussbaum writes:

A lot is at stake in the decision to view emotions in this way, as intelligent responses to the perception of value. If emotions are suffused with intelligence and discernment, and if they contain in themselves an awareness of value or importance, they cannot, for example, easily be sidelined in accounts of ethical judgment, as so often they have been in the history of philosophy. Instead of viewing morality as a system of principles to be grasped by the detached intellect, and emotions as motivations that either support or subvert our choice to act according to principle, we will have to consider emotions as part and parcel of the system of ethical reasoning. We cannot plausibly omit them, once we acknowledge that emotions include in their content judgments that can be true or false, and good or bad guides to ethical choice. We will have to grapple with the messy material of grief and love, anger and fear, and the role these tumultuous experiences play in thought about the good and the just.

Emotions are not just the fuel that powers the psychological mechanism of a reasoning creature, they are parts, highly complex and messy parts, of this creature’s reasoning itself.
