Abstract
This paper presents Stoicism as, in broad historical terms, the point of origin in Western thought of an extreme form of rational essentialism that persists today in the debate over human bioenhancement. Advocates of “radical” enhancement would have us codify extreme rational essentialism through manipulation of genes and the brain to maximize rational ability and eliminate the capacity for emotions deemed unsalutary. They, like Stoics, see anger as especially dangerous. The ancient dispute between Stoics and Aristotle over the nature and permissibility of anger has contemporary analogues. I argue that, on the merits, this controversy should, finally, be put to rest in Aristotle’s favor. Beyond its philosophical assets, Aristotle’s perspective meshes well with “appraisal theory” of emotion in psychology and corresponding discoveries in neuroscience. What’s more, consideration of the ongoing struggle to achieve full racial equality in the United States supports the view that anger at this ongoing gap between λόγος and ἔργον is legitimate, and has a constructive role to play in furthering liberal democracy. As we are well positioned to retire the Stoics’ legacy regarding anger, all the more should we eschew transhumanists’ proposal to implement their position biologically, at which point debate over the nature and worth of anger would be permanently moot.
