Machian Comparativism about Mass

Absolutism about mass within Newtonian gravity claims that ratios obtain in virtue of absolute masses. Comparativism denies this. Defenders comparativism promise to recover all the empirical and theoretical virtues absolutism, but at a lower ‘metaphysical cost’. This article develops Machian form gravity, obtained by replacing Newton’s constant law universal gravitation another divided sum over Although this is indeed empirically equivalent absolutist version gravity—thereby meeting challenge posed comparativist’s bucket argument—it argued explanatory power metaphysical parsimony (and especially its form) are highly questionable.
