The notion that an objectively “good life” extends to seventy or a hundred years but no further is clearly arbitrary, and yet the opinion that it does is both nearly universally held and violently defended. It illustrates how people can easily become staunch defenders of existing catastrophes for fear of otherwise having to reconsider standing assumptions in their own lives. In the same way that people will defend mandatory military service or murdering animals for food, the arguments for death are clearly defensive rationalizations—and rational responses are easy to formulate. Life extension is an illustrative example that gets to the heart of what transhumanism offers as a continuation of anarchism’s radicalism: the capacity to demand that unexamined norms or conventions justify themselves, to challenge things otherwise accepted.
