Ian Stoner

Domain: space-development
Type: person
Role: Philosophy professor

Overview

Ian Stoner is a philosopher who argued against Mars colonization on environmental ethics grounds in his 2017 paper, applying the Principle of Scientific Conservation (PSC) to argue that Mars should remain pristine as a scientifically valuable object.

Key Positions

Anti-Mars colonization argument (2017):

  • Applied Principle of Scientific Conservation to Mars
  • Argued there are no countervailing considerations that override the PSC obligation
  • Compared Mars to the Great Pyramids: studying them for 100+ years doesn't justify converting them to hotels
  • Position was later challenged by Gottlieb (2019) on existential risk grounds

Timeline

  • 2017 — Published argument against Mars colonization based on Principle of Scientific Conservation
  • 2019 — Gottlieb published rebuttal arguing existential risk mitigation overrides PSC concerns
