  1. Infinite Aggregation.Hayden Wilkinson - 2021 - Dissertation, Australian National University
    Suppose you found that the universe around you was infinite—that it extended infinitely far in space or in time and, as a result, contained infinitely many persons. How should this change your moral decision-making? Radically, it seems, according to some philosophers. According to various recent arguments, any moral theory that is ’minimally aggregative’ will deliver absurd judgements in practice if the universe is (even remotely likely to be) infinite. This seems like sound justification for abandoning any such theory. -/- My (...)

  2. Infinite Aggregation and Risk.Hayden Wilkinson - forthcoming - Australasian Journal of Philosophy.
    For aggregative theories of moral value, it is a challenge to rank worlds that each contain infinitely many valuable events. And, although there are several existing proposals for doing so, few provide a cardinal measure of each world's value. This raises the even greater challenge of ranking lotteries over such worlds—without a cardinal value for each world, we cannot apply expected value theory. How then can we compare such lotteries? To date, we have just one method for doing so (proposed (...)

  3. Chaos, Add Infinitum.Hayden Wilkinson - manuscript
    Our universe is both chaotic and (most likely) infinite in space and time. But it is within this setting that we must make moral decisions. This presents problems. The first: due to our universe's chaotic nature, our actions often have long-lasting, unpredictable effects; and this means we typically cannot say which of two actions will turn out best in the long run. The second problem: due to the universe's infinite dimensions, and infinite population therein, we cannot compare outcomes by simply (...)

    Infinite aggregation: expanded addition.Hayden Wilkinson - 2020 - Philosophical Studies 178 (6):1917-1949.
    How might we extend aggregative moral theories to compare infinite worlds? In particular, how might we extend them to compare worlds with infinite spatial volume, infinite temporal duration, and infinitely many morally valuable phenomena? When doing so, we face various impossibility results from the existing literature. For instance, the view we adopt can endorse the claim that worlds are made better if we increase the value in every region of space and time, or that they are made better if we (...)

  5. In Defense of Fanaticism.Hayden Wilkinson - 2022 - Ethics 132 (2):445-477.
    Which is better: a guarantee of a modest amount of moral value, or a tiny probability of arbitrarily large value? To prefer the latter seems fanatical. But, as I argue, avoiding such fanaticism brings severe problems. To do so, we must decline intuitively attractive trade-offs; rank structurally identical pairs of lotteries inconsistently, or else admit absurd sensitivity to tiny probability differences; have rankings depend on remote, unaffected events ; and often neglect to rank lotteries as we already know we would (...)

    Aggregation in an Infinite, Relativistic Universe.Hayden Wilkinson - manuscript
    Aggregative moral theories face a series of devastating problems when we apply them in a physically realistic setting. According to current physics, our universe is likely _infinitely large_, and will contain infinitely many morally valuable events. But standard aggregative theories are ill-equipped to compare outcomes containing infinite total value so, applied in a realistic setting, they cannot compare any outcomes a real-world agent must ever choose between. This problem has been discussed extensively, and non-standard aggregative theories proposed to overcome it. (...)

  7. Market Harms and Market Benefits.Hayden Wilkinson - forthcoming - Philosophy and Public Affairs.
    Our actions in the marketplace often harm others. For instance, buying and consuming petroleum contributes to climate change and thereby does harm. But there is another kind of harm we do in almost every market interaction: market harms. These are harms inflicted via changes to the goods and/or prices available to the victim in that market. (Similarly, market benefits are those conferred in the same way.) Such harms and benefits may seem morally unimportant, as Judith Jarvis Thomson and Ronald Dworkin (...)
