R. M. Hare

R. M. Hare mattered to Peter Singer less as a master to be repeated than as a philosopher who supplied the discipline Singer would keep even when he outgrew the local Oxford style. Hare’s central concern was the logic of moral language: what we are doing when we say someone ought to act, and what follows if moral judgments are genuinely universal. Beneath the cool analytic surface was a man driven by a powerful demand for order. Hare distrusted moral emotivism, casual relativism, and the comforting suspicion that ethics could be left to sentiment. He wanted a form of moral reasoning that could not be bent to favor the speaker’s tribe, class, or convenience.

In The Language of Morals and Freedom and Reason, Hare developed universal prescriptivism, the view that moral judgments commit us to prescribing consistently across relevantly similar cases. This was not merely a technical thesis. It was Hare’s answer to a deeper anxiety: if moral language does not bind us even when it is inconvenient, then morality collapses into performance. He treated consistency as a moral discipline in itself, almost a test of integrity. Singer absorbed from this the deep idea that moral reasoning cannot be a private language of exemptions. If I judge one case as wrong, I must be ready to judge like cases alike, regardless of whether I happen to occupy the advantaged position in them.

Hare’s own utilitarianism was not identical to Singer’s, but he helped normalize a style of moral thought in which consistency, action-guidance, and universalizability are central. That style had a hidden hardness. It stripped away evasions, but it also narrowed the room for moral comfort. The attraction for Singer is easy to see: Hare offered a method that seemed to make hypocrisy harder. The cost was that moral life risked becoming too clean, too formal, too confident that once one had universalized a principle, one had actually understood the human damage it would produce or prevent.

Hare’s personality as a philosopher seems marked by a tension between abstraction and moral seriousness. Publicly, he stood for rigor, neutrality, and argumentative discipline. Privately, that same discipline could become a way of avoiding the messier claims of power, history, and embodied suffering that other thinkers insisted on placing at the center of ethics. He was not indifferent to practical life, but he remained more interested in what moral statements mean than in what institutions do to people. That choice had consequences: it made his work clean, influential, and teachable, but it also meant that the suffering of actual persons could appear as an input to theory rather than as a destabilizing reality demanding political response.

Singer’s early utilitarian arguments inherit Hare’s structure, even as he pushes it toward more concrete and urgent applications. The interesting tension in Hare’s influence is that he provided a formal engine without fully determining Singer’s destination. Singer turned the engine outward toward famine, animals, and bioethics. Hare remained more a theorist of moral logic than a campaigner for the practical reform of the world. In that sense, Singer is one of the most visible examples of what happens when Oxford analysis leaves the room and enters public life.

Hare’s legacy in this story is foundational but indirect: he supplied one of the cleanest routes from moral language to moral impartiality, and Singer took that route farther than Hare himself had intended. The result is a philosophical lineage with a moral price tag: clarity purchased at the expense of innocence, and a demand for consistency that can expose not only the weakness of our excuses but also the limits of the theory that strips them away.
