I was struck by two things when I read Martha Nussbaum’s Anger and Forgiveness. On one hand, as I noted previously, I’m excited by Nussbaum’s new, and more Śāntidevan, normative approach to anger; it seems like she and I have moved toward the same position there. On the other, though, I realized that I have moved away from Nussbaum’s general descriptive theory of emotion. Nussbaum articulates this theory at length in Upheavals of Thought, and I don’t think her theory has changed much by the time we get to Anger (she offers a summary of it in the appendix). What has changed, in the roughly fifteen years since I read Upheavals cover to cover, is that I agreed with her theory then, and I no longer do – and reading the short summaries of the position in Anger helped me realize that.
Nussbaum’s theory (derived primarily from the Stoic thinker Chrysippus) is that emotions are fundamentally cognitive judgements of value, with a content directed at an object believed to affect our well-being. So fear, for example, is primarily a judgement that something could be harmful to us in the future; grief is primarily a judgement that something of value has been lost to us. I found this account plausible when I first encountered it. I no longer do.
