In recent years, several philosophers have argued that their discipline makes no progress (or not enough in comparison to the “hard sciences”). A key argument for this pessimistic position appeals to the purported fact that philosophers widely and systematically disagree on most major philosophical issues. In this paper, we take a step back from the debate about progress in philosophy specifically and consider the general question: How (if at all) would disagreement within a discipline undermine that discipline’s progress? We reject (...) two arguments from disagreement to a lack of progress, and spell out two accounts of progress on which progress is compatible with disagreements that persist or increase over time. However, we also argue that disagreement can undermine our ability to tell which developments are progressive (and to what degree). So, while disagreement can indeed be a threat to progress, the precise nature of the threat has not been appreciated. (shrink)

What is scientific progress? This paper advances an interpretation of this question, and an account that serves to answer it. Roughly, the question is here understood to concern what type of cognitive change with respect to a topic X constitutes a scientific improvement with respect to X. The answer explored in the paper is that the requisite type of cognitive change occurs when scientific results are made publicly available so as to make it possible for anyone to increase their understanding (...) of X. This account is briefly compared to two rival accounts of scientific progress, based respectively on increasing truthlikeness and accumulating knowledge, and is argued to be preferable to both.

Is there progress in philosophy? If so, how much? Philosophers have recently argued for a wide range of answers to these questions, from the view that there is no progress whatsoever to the view that philosophy has provided answers to all the big philosophical questions. However, these views are difficult to compare and evaluate, because they rest on very different assumptions about the conditions under which philosophy would make progress. This paper looks to the comparatively mature debate about scientific progress (...) for inspiration on how to formulate four distinct accounts of philosophical progress, in terms of truthlikeness, problem-solving, knowledge, and understanding. Equally importantly, the paper outlines a common framework for how to understand and evaluate these accounts. We distill a series of lessons from this exercise, to help pave the way for a more fruitful discussion about philosophical progress in the future. (shrink)

What is scientific progress? On Alexander Bird’s epistemic account of scientific progress, an episode in science is progressive precisely when there is more scientific knowledge at the end of the episode than at the beginning. Using Bird’s epistemic account as a foil, this paper develops an alternative understanding-based account on which an episode in science is progressive precisely when scientists grasp how to correctly explain or predict more aspects of the world at the end of the episode than at the (...) beginning. This account is shown to be superior to the epistemic account by examining cases in which knowledge and understanding come apart. In these cases, it is argued that scientific progress matches increases in scientific understanding rather than accumulations of knowledge. In addition, considerations having to do with minimalist idealizations, pragmatic virtues, and epistemic value all favor this understanding-based account over its epistemic counterpart. (shrink)

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

Is there progress in philosophy? A glass-half-full view is that there is some progress in philosophy. A glass-half-empty view is that there is not as much as we would like. I articulate a version of the glass-half-empty view, argue for it, and then address the crucial question of what explains it.

Controversial view agnosticism is the thesis that we are rationally obligated to withhold judgment about a large portion of our beliefs in controversial subject areas, such as philosophy, religion, morality and politics. Given that one’s social identity is in no small part a function of one’s positive commitments in controversial areas, CVA has unsurprisingly been regarded as objectionably ‘spineless.’ That said, CVA seems like an unavoidable consequence of a prominent view in the epistemology of disagreement—conformism—according to which the rational response (...) to discovering that someone you identify as an epistemic peer or expert about p disagrees with you vis-à-vis p is to withhold judgment. This paper proposes a novel way to maintain the core conciliatory insight without devolving into an agnosticism that is objectionably spineless. The approach offered takes as a starting point the observation that–for reasons that will be made clear—the contemporary debate has bypassed the issue of the reasonableness of maintaining, rather than giving up, representational states weaker than belief in controversial areas. The new position developed and defended here explores this overlooked space; what results is a kind of controversial view. (shrink)

Is there enough progress in philosophy? It is notable that even within the discipline, opinions are divided. Optimists think there is more than enough progress in philosophy. Pessimists think we could and should do better. In this chapter I defend an optimistic answer to this question.

I argue that scientific progress is precisely the accumulation of scientific knowledge.

David Lewis and Peter van Inwagen have claimed that there are no “knockdown” arguments in philosophy. Their claim appears to be at odds with common philosophical practice: philosophers often write as though their conclusions are established or proven and that the considerations offered for these conclusions are decisive. In this paper, I examine some questions raised by Lewis’s and van Inwagen’s contention. What are knockdown arguments? Are there any in philosophy? If not, why not? These questions concern the nature of (...) the philosophical enterprise and our answers have implications for the limits on the attitudes of informed, rational thinkers. (shrink)

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

Philosophy, as I use it here, is a conversation, one stretching back through various canonical European and Ancient Greek texts at least to Thales. Has this conversation progressed? The main objection to philosophy's having a linear progression is dissensus – the fact that philosophers all disagree but still accept each other as peers. In this chapter, I argue that we should conceive of philosophy as being capable of a branching kind of progression: philosophy progresses when it gives us more ways (...) of conceiving of ourselves. (shrink)

I argue that philosophy has achieved no appreciable progress in making people better and wiser or solving its own central problems. This lack of progress matters, but I find hope in experimental philosophy. Although philosophical worldviews from Plato's to the present have aided comprehension of how things hang together, their only steady progress has come from adjusting to advances in science. If the power of philosophy were like the power of poetry, this would not matter. Each worldview could be appreciated (...) in its own right. Yet most authors of philosophical worldviews have sought solutions to philosophical problems that would be persuasive to anyone who was willing and able to follow their arguments. Without progress of this kind, philosophy runs the risk of being marginalized. I conclude by arguing that experimental philosophy offers the best hope for philosophy's progress as a problem‐solving discipline and defend the use of intuitions as evidence. (shrink)

Many people believe that philosophy makes no progress. Members of the general public often find it amazing that philosophers exist in universities at all, at least in research positions. Academics who are not philosophers often think of philosophy either as a scholarly or interpretative enterprise, or else as a sort of pre-scientific speculation. And many well-known philosophers argue that there is little genuine progress in philosophy. Daniel Stoljar argues that this is all a big mistake. When you think through exactly (...) what philosophical problems are, and what it takes to solve them, the pattern of success and failure in philosophy is similar to that in other fields. In philosophy, as elsewhere, there is a series of overlapping topics that determine what the subject is about. In philosophy, as elsewhere, different people in different historical epochs and different cultures ask different big questions about these topics. And in philosophy, as elsewhere, big questions asked in the past have often been solved: Stoljar provides examples. Philosophical Progress presents a strikingly optimistic picture of philosophy - not a radical optimism that says that there is some key that unlocks all philosophical problems, and not the kind of pessimism that dominates both professional and non-professional thinking about philosophy, but a reasonable optimism that views philosophy as akin to other fields.

Should we believe our controversial philosophical views? Recently, several authors have argued from broadly conciliationist premises that we should not. If they are right, we philosophers face a dilemma: If we believe our views, we are irrational. If we do not, we are not sincere in holding them. This paper offers a way out, proposing an attitude we can rationally take toward our views that can support sincerity of the appropriate sort. We should arrive at our views via a certain (...) sort of ‘insulated’ reasoning – that is, reasoning that involves setting aside certain higher-order worries, such as those provided by disagreement – when we investigate philosophical questions.

In this introduction, I summarize the main themes of my book, particularly those that my critics have focused on in their papers that follow. I also argue that I could not have reached the conclusions that I have if I hadn’t employed a peacemaking rather than a warmaking way of doing philosophy. I provide a characterization of a peacemaking way of doing philosophy and show how the conclusions of my book depend on doing philosophy in that way.

In response to widespread doubts among professional philosophers (Russell, Horwich, Dietrich, McGinn, Chalmers), Stoljar argues for a ‘reasonable optimism’ about progress in philosophy. He defends the large and surprising claim that ‘there is progress on all or reasonably many of the big questions.’ However, Stoljar’s caveats and admitted avoidance of historical evidence permits overlooking persistent controversies in philosophy of mind and cognitive science that are essentially unchanged since the 17th Century. Stoljar suggests that his claims are commonplace in philosophy departments (...) and, indeed, the evidence I adduce constitutes an indictment of the widely shared view among professional analytic philosophers.

Philosophical progress is one of the most controversial topics in metaphilosophy. It has been widely debated whether philosophy makes any progress in history. This paper revisits the concept of philosophical progress. It first identifies two criteria of an ideal concept of philosophical progress. It then argues that our accounts of philosophical progress fail to provide such an ideal concept. Finally, it argues that not only do we not have a good concept of philosophical progress, we also do not need a (...) concept of philosophical progress in order to arrive at a good understanding of the history of philosophy.

What credence should we assign to philosophical claims that were formed without any knowledge of the current state of the art of the philosophical debate and little or no knowledge of the relevant empirical or scientific data? Very little or none. Yet when we engage with the history of philosophy, this is often exactly what we do. In this paper, I argue that studying the history of philosophy is philosophically unhelpful. The epistemic aims of philosophy, if there are any, are (...) frustrated by engaging with the history of philosophy, because we have little reason to think that the claims made by history’s great philosophers would survive closer scrutiny today. First, I review the case for philosophical historiography and show how it falls short. I then present several arguments for skepticism about the philosophical value of engaging with the history of philosophy and offer an explanation for why philosophical historiography would seem to make sense even if it didn’t.

According to the foundationalist picture, shared by many rationalists and positivist empiricists, science makes cognitive progress by accumulating justified truths. Fallibilists, who point out that complete certainty cannot be achieved in empirical science, can still argue that even successions of false theories may progress toward the truth. This proposal was supported by Karl Popper with his notion of truthlikeness or verisimilitude. Popper’s own technical definition failed, but the idea that scientific progress means increasing truthlikeness can be expressed by defining degrees (...) of truthlikeness in terms of similarities between states of affairs. This paper defends the verisimilitude approach against Alexander Bird who argues that the “semantic” definition is not sufficient to define progress, but the “epistemic” definition referring to justification and knowledge is more adequate. Here Bird ignores the crucial distinction between real progress and estimated progress, explicated by the difference between absolute degrees of truthlikeness and their evidence-relative expected values. Further, it is argued that Bird’s idea of returning to the cumulative model of growth requires an implausible trick of transforming past false theories into true ones. (shrink)

This article seeks to clarify the concept of progress in philosophy. It treats progress as a kind of development. But not every development is a progress. When we talk about progress, what really matters is the direction of development. In some cases it is relatively easy to reach agreement about this direction. But not in the case of philosophy, if we abstract it from the obvious and the trivial, like the number of books on philosophy. As a result, the article (...) concludes that there cannot be progress in philosophy. Instead we see a continual multiplication of interpretations. (shrink)

A priori metaphysics has come under repeated attack by naturalistic metaphysicians, who take their closer connection to the sciences to confer greater epistemic credentials on their theories. But it is hard to see how this can be so unless the problem of theory change that has for so long vexed philosophers of science can be addressed in the context of scientific metaphysics. This paper argues that canonical metaphysical claims, unlike their scientific counterparts, cannot meaningfully be regarded as ‘approximately true,’ and (...) that this means that the epistemic progress that science arguably enjoys through episodes of theory change cannot be expected to transfer to its metaphysics. What the value of engaging in metaphysics of science before the emergence of a final theory becomes correspondingly unclear. (shrink)

Nathan Ballantyne argues that the knockdown status of certain non-philosophical arguments can be transferred to arguments for substantive philosophical conclusions. Thus, if there are knockdown non-philosophical arguments, there are knockdown philosophical arguments. I show that Ballantyne’s argument is unsound, since arguments that are knockdown in non-philosophical contexts may become question-begging when used to argue for philosophical conclusions.

The following three propositions appear to be individually defensible but jointly inconsistent: (1) reliability is a necessary condition on epistemic justification; (2) on contested matters in philosophy, my beliefs are not reliably formed; (3) some of these beliefs are epistemically justified. I explore the nature and scope of the problem, examine and reject some candidate solutions, compare the issue with ones arising in discussions about disagreement, and offer a brief assessment of our predicament.

From the acclaimed writer and thinker--whose award-winning books include both fiction and non-fiction--a dazzlingly original plunge into the drama of philosophy, revealing its hidden but essential role in today's debates on love, religion, politics, and science. Imagine that Plato came to life in the 21st century and set out on a multi-city speaking tour: How would he handle a host on Fox News who challenges him on religion and morality? How would he mediate a debate on the best way to (...) raise a child between a Freudian psychoanalyst and a Tiger Mom? How would he answer a neuroscientist who, about to scan Plato's brain, argues that all his philosophical problems can be solved by our new technologies? What would he make of Google, and the idea that knowledge can be crowdsourced rather than reasoned out by experts? With a philosopher's depth and a novelist's imagination, Rebecca Newberger Goldstein probes the deepest issues confronting us--from sexuality and child-rearing to morality and the meaning of life--by allowing us to eavesdrop on Plato as he encounters the modern world. By reviving the Platonic art of the dialogue for the 21st century, she demonstrates that the questions he first posed continue to confound and enlarge us. (shrink)

Except for a patina of twenty-first century modernity, in the form of logic and language, philosophy is exactly the same now as it ever was; it has made no progress whatsoever. We philosophers wrestle with the exact same problems the Pre-Socratics wrestled with. Even more outrageous than this claim, though, is the blatant denial of its obvious truth by many practicing philosophers. The No-Progress view is explored and argued for here. Its denial is diagnosed as a form of anosognosia, a (...) mental condition where the affected person denies there is any problem. The theories of two eminent philosophers supporting the No-Progress view are also examined. The final section offers an explanation for philosophy 's inability to solve any philosophical problem, ever. The paper closes with some reflections on philosophy 's future. (shrink)

This book combines the two most common approaches used to introduce students or general readers to ethics: the historical and the applied. Using these approaches, Sterba examines traditional ethical theories and disagreements, exploring Aristotelian, Kantian, and utilitarian ethics, as well as their contemporary defenders. But rather than focusing on formal aspects of these views, Sterba applies the best practical arguments from each of these perspectives to a variety of moral problems, such as sexual harassment, affirmative action, and international terrorism and (...) the second Iraqi war.

The first volume of this series presents fifteen selected papers dealing with a variety of topics in ontology, philosophy of mind, and philosophy of language.

This is a collective study of the epistemic significance of disagreement: twelve contributors explore rival responses to the problems that it raises for philosophy. They develop our understanding of epistemic phenomena that are central to any thoughtful engagement with others' beliefs.
