Written By His Students Jacob Barrett Adam Gjesdal Bill Glod Keith Hankins Brian Kogelmann Ryan Muldoon John Thrasher Kevin Vallier Chad Van Schoelandt It is difficult to describe Jerry Gaus’s views and accomplishments in part because he was so prolific, having authored nine books comprising roughly 3,000 pages and more than a hundred published papers. Moreover, his work was wide-ranging and interdisciplinary. Jerry was critical of what he sometimes called “hedgehogosity,” the tendency for political philosophers to define themselves in terms of well-defined schools or even a single supreme value. In contrast to the hedgehog’s narrowness, consider how Jerry describes his work in The Order of Public Reason (2011, xiv–xv): “we will have to grapple with the insights of, among many others, Hobbes, Hume, Kant, Rousseau, J. S. Mill, T. H. Green, P. F. Strawson, Kurt Baier, S. I. Benn, R. M. Hare, F. A. Hayek, David Gauthier, Alan Gewirth, Kenneth Arrow, John Rawls, James Buchanan, and Amartya Sen. We will draw on game theory, experimental psychology, theories of emotion and reasoning, axiomatic social choice theory, constitutional political economy, Kantian moral philosophy, prescriptivism, and the concept of reason and how it relates to freedom in human affairs.” Jerry (2011, xv) noted that his “work is often categorized under the ‘libertarian’ label since I argue that human freedom is terribly important, that coercive interferences infringe freedom and so must always be justified to the person who is being coerced.” He wrote this not to embrace a libertarian label, but to reject it, as Jerry stressed his concerns with coercion came from his friend and co-author Stanley Benn, an Australian Labor Democrat. Indeed, Jerry’s bête noire was political ideology of all kinds, including libertarianism, because adopting them detracts one from “the truth business,” as his advisor John Chapman taught him. Jerry understood himself to be working in a tradition with an ongoing, active research agenda for a scholarly community, teaching us about the complexities of our social world, rather than looking for opportunities to reinforce our biased ways of understanding it. For this reason, we want to emphasize not merely Jerry’s accomplishments, like his major books, but also the ongoing projects and areas in which he played a pivotal role. Public Reason Jerry is best known for his work in the public reason tradition, particularly as he was the leading figure in what has come to be known as convergence liberalism. He had worked on the idea of public reason at the same time as Rawls was – during the 1980s. Jerry produced his first work in the area in 1990: Value and Justification.[i] Throughout his career, Jerry was heavily influenced by the great social contract theorists – Hobbes, Locke, Rousseau, and Kant – as well as contemporary theorists like Rawls and David Gauthier. From very early on, Jerry recognized that living in a complex social order required a kind of agreement amongst its members on the terms of social life. As he understood them, the social contract theorists recognized that engaging in moral reasoning about how to live from a purely first-personal point of view was bound to lead to destructive conflict. So, in a deep study of how humans make value judgments, the nature of the moral emotions and a theory of moral maturation, Jerry argued that we must come to move beyond the first-personal point of view and to integrate a social perspective into our individual perspectives. Only in this way can humans successfully cooperate with one another. Taking the perspective of others was also a pre-requisite for maintaining our personal relationships. Doing so is central to sustaining valuable relations of love, friendship, and trust. All relationships require that we follow certain kinds of rules and moral requirements that involve taking the perspective of others into account. The doctrine of public reason is derived from Jerry’s account of personal values and the norms internal to personal relationships. We pursue public justifications for our shared rules of social life in order to ensure that the rules are acceptable to all, such that persons can related to one another by way of complying with those rules. Jerry would stress the importance of shared reasoning in helping us live together. Yet, even there, we find a role for pluralistic and diverse reasoning in formulating a justification for our moral demands on one another, though the theme was not as central as it would become in later work. As Jerry was working on his next book, Justificatory Liberalism, he came to embrace more pluralistic forms of reasoning, allowing diverse reasoning to supplement shared reasoning more and more. In the terms of Jerry’s good friend and fellow public reason theorist, Fred D’Agostino, Jerry had moved away from the mainstream “consensus” model of public reason of expecting an agreement about which reasons could be appealed to in justifying social and political power and coercion, and supplanted it with a “convergence” view where diverse reasons could figure into the justification of coercive political power. Yet even here, Jerry adopted a principle of sincerity that required citizens to engage in shared reasons in justifying moral and political claims to one another. Over the next fifteen years, in the build-up to The Order of Public Reason, Jerry would increasingly stress the incompleteness of the social contract tradition. The difficulty with mainstream ideas of public reason is that they supposed a society could reach an agreement about principles of morality and justice. But it became a central theme of OPR that this was an unrealistic expectation. Jerry also stressed, in contrast to Justificatory Liberalism, that we could not rely on the political process alone in choosing between proposals that could only be “inconclusively” justified to all. Instead, we would have to appeal to social evolution in order to come upon concrete agreements. Kant and Rawls would have to join forces with Hume and Hayek. An “order of public reason” would not be a “deliberative democracy” that would narrow our disagreements to consensus, on reasons or on public policy;
