Derek Parfit briefly considers a similar argument in the concluding section of Reasons and Persons. On this argument, “what matters are what Sidgwick called the ‘ideal goods’—the Sciences, the Arts, and moral progress, or the continued advance towards a wholly just world-wide community. The destruction of mankind would prevent further achievements of these three kinds. This would be extremely bad because what matters most would be the highest achievements of these kinds, and these highest achievements would come in future centuries.” (p. 454) However, although not strictly utilitarian, the argument is still broadly consequentialist.
