In particular, Leon Kass has argued that living longer is not such a great advantage, and that mortality is not a burden after all. In this essay, I evaluate his arguments in favour of such a counterintuitive view by elaborating upon some critical remarks advanced by John Harris. Ultimately, I argue that nothing substantial has been said by Kass to undermine the desirability of life-extending technologies.
