Abstract
This paper considers the argument that we have a duty to colonise other planets because we owe it to future generations. It puts forward the view that formulations of this argument in the current literature are confused. It distinguishes (at least) four versions of the argument and shows that none of them are compelling. It draws the conclusion that, should people put forward these arguments, they ought to be more precise in their formulations and more rigorous in their defence.
