“Consequentialism, Cluelessness, Clumsiness, and Counterfactuals”

By Alan Hájek, Professor of Philosophy at Australian National University, and Fellow of the Australian Academy of the Humanities

Abstract: According to objective consequentialism, a morally right action is one that has the best consequences. (These are not just the immediate consequences of the actions, but the long-term consequences, perhaps until the end of history.) I will argue that on one understanding this makes no sense, and on another understanding, it has a startling metaphysical presupposition concerning counterfactuals. Objective consequentialism has faced various objections, including the problem of “cluelessness”: we have no idea what most of the consequences of our actions will be. I think that on these understandings, objective consequentialism has a far worse problem: its very foundations are highly dubious. Even granting these foundations, a worse problem than cluelessness remains, which I call “clumsiness”. Moreover, I think that these problems quickly generalise to a number of other moral theories. But the point is most easily made for objective consequentialism, so I will focus largely on it.

I will consider three ways that objective consequentialism might be improved:

    1. Appeal instead to short-term consequences of actions;

    2. Understand consequences with objective probabilities;

    3. Understand consequences with subjective/evidential probabilities.

But even here, there be dragons.

Graduate students at KCL Philosophy are organising an interdisciplinary conference on Infinity taking place next Friday and Saturday (12th – 13th May). The conference features keynote addresses from Adrian Moore (Oxford) and Øystein Linnebo (Oslo). Here is the description from the organisers, Amedeo Robiolio and Pablo Dopico:

To study infinity is to study things which have no limit, no ends, or no bounds. Consequently, it touches the areas of study of philosophers, scientists and mathematicians in a remarkable number of ways, and often causing interesting difficulties in doing so, some of which, such as Zeno’s paradoxes of Hilbert’s hotel, have achieved great popularity. Infinity is philosophically relevant in Mathematics, with issues such as the different sizes of infinity, the topic of infinitesimals, and the problems of infinity in probabilistic mathematics.

But infinity encompasses a much wider range of philosophical issues than those present in the philosophy of mathematics. In metaphysics and the philosophy of physics, the issues both of infinite extension and infinite divisibility of space and of time have troubled thinkers for millennia. In the Philosophy of Religion, the infinity of God is a vast and ancient area of investigation. Indeed, the history of the philosophy of infinity, engaging with the long and complex evolution of this topic is itself an important area of research.

The conference aims to bring together researches working on all of these different perspectives on Infinity and more, hoping that this encounter will mutually benefit the advancements of these areas.
