Current epistemological orthodoxy has it that knowledge is incompatible with luck. More precisely: Knowledge is incompatible with epistemic luck . This is often treated as a truism which is not even in need of argumentative support. In this paper, I argue that there is lucky knowledge. In the first part, I use an intuitive and not very developed notion of luck to show that there are cases of knowledge which are “lucky” in that sense. In the second part, I look at philosophical conceptions of luck and come to the conclusion that knowledge can be lucky in those senses, too. I also turns out that a probabilistic notion of luck can help us see in what ways a particular piece of knowledge or belief can be lucky or not lucky

Christoph Jäger (2004) argues that Dretske's information theory of knowledge raises a serious problem for his denial of closure of knowledge under known entailment: Information is closed under known entailment (even under entailment simpliciter); given that Dretske explains the concept of knowledge in terms of "information", it is hard to stick with his denial of closure for knowledge. Thus, one of the two basic claims of Dretske would have to go. Since giving up the denial of closure would commit Dretske to skepticism, it would most probably be better to rather give up the information-theoretic account of knowledge. But that means that one of the best externalist views of knowledge has to be given up. I argue here that Jäger is mistaken and that there is no problem for Dretske. There is a rather easy way out of Jäger’s problem.

For each of the many goals of an agent it is true that the agent wants its realization. Given further very plausible assumptions, one can show that there is no good reason for an agent not to want the realization of all of his goals. However, it seems also true that reaching all of one’s goals would be extremely boring; most human beings would consider such a life not worth living. In this respect, leading a life is like playing some game: A game loses its point if one always easily wins. Human agents not only pursue goals but they also have the second-order desire to lead the life of a goal-pursuer. More precisely, they want to be goal-pursuers such that many but not all of their goals are being realized. I argue here that they have a good reason not to want the realization of all of their goals. Now, all this constitutes an antinomy: Apparently, there are very plausible arguments both for affirming as well as denying that an agent has good reasons not to want the realization of his goals. This antinomy is similar to the preface-paradox about beliefs which has a convincing solution (due to Frank Ramsey). I argue, however, that there is no such solution in the case of goals. This leaves us with the question what a solution could look like.

One of the most recent trends in epistemology is contrastivism. It can be characterized as the thesis that knowledge is a ternary relation between a subject, a proposition known and a contrast proposition. According to contrastivism, knowledge attributions have the form “S knows that p, rather than q”. In this paper I raise several problems for contrastivism: it lacks plausibility for many cases of knowledge, is too relaxed concerning the third relatum, and overlooks a further relativity of the knowledge relation.

One of the most important views in the recent discussion of epistemological scepticism is Neo-Mooreanism. It turns a well-known kind of sceptical argument (the dreaming argument and its different versions) on its head by starting with ordinary knowledge claims and concluding that we know that we are not in a sceptical scenario. This paper argues that George Edward Moore was not a Moorean in this sense. Moore replied to other forms of scepticism than those mostly discussed nowadays. His own anti-sceptical position turns out to be very subtle and complex; furthermore it changed over time. This paper follows Moore's views of what the sceptical problem is and how one should respond to it through a series of crucial papers with the main focus being on Moore's 'Proof of an External World'. An appendix deals with the much neglected relation between epistemological scepticism and moral scepticism in Moore.

There is a sceptical puzzle according to which knowledge appears to license an unacceptable kind of dogmatism. Here is a version of the corresponding sceptical argument: (1) If a subject S knows a proposition p, then it is OK for S to ignore all evidence against p as misleading; (2) It is never OK for any subject to ignore any evidence against their beliefs as misleading; (3) Hence, nobody knows anything.I distinguish between different versions of the puzzle (mainly a ‘permissibility’ version and a ‘closure’ version) and offer a solution for one version (the permissibility version) of the problem. No matter how much a subject knows, knowledge never gives one a license to ignore evidence against a proposition. Premise (1) of the argument is false and the puzzle can thus be resolved

This paper discusses two versions of reliabilism: modal and probabilistic reliabilism. Modal reliabilism faces the problem of the missing closeness metric for possible worlds while probalistic reliabilism faces the problem of the relevant reference class. Despite the severity of these problems, reliabilism is still very plausible (also for independent reasons). I propose to stick with reliabilism, propose a contextualist (or, alternatively, harmlessly relativist) solution to the above problems and suggest that probabilistic reliabilism has the advantage over modal reliabilism.

Human dignity seems very important to us. At the same time, the concept ‘human dignity’ is extrordinarily elusive. A good way to approach the questions “What is it?” and “Why is it important?” is to raise another question first: In virtue of what do human beings have dignity? Speciesism - the idea that human beings have a particular dignity because they are humans - does not seem very convincing. A better answer says that human beings have dignity because and insofar as they are persons. I discuss several versions of this idea as well as several objections against it. The most promising line of analysis says that human beings cannot survive psychologically without a very basic form of recognition and respect by others. The idea that humans have a very special dignity is the idea that they owe each other this kind of respect. All this also suggests that human dignity is inherently social. Non-social beings do not have dignity - nor do they lack it. It is because we are social animals of a certain kind that we have dignity - not so much because we are rational animals.

There are many ordinary propositions we think we know. Almost every ordinary proposition entails some "lottery proposition" which we think we do not know but to which we assign a high probability of being true (for instance: “I will never be a multi-millionaire” entails “I will not win this lottery”). How is this possible - given that some closure principle is true? This problem, also known as “the Lottery puzzle”, has recently provoked a lot of discussion. In this paper I discuss one of the most promising answers to the problem: Stewart Cohen’s contextualist solution which is based on ideas about the salience of chances of error. After presenting some objections to it I sketch an alternative solution which is still contextualist in spirit.

In his recent book Moral Skepticisms Walter Sinnott-Armstrong argues in great detail for contrastivism with respect to justified moral belief and moral knowledge. I raise three questions concerning this view. First, how would Sinnott-Armstrong account for constraints on admissible contrast classes? Secondly, how would he deal with notorious problems concerning relevant reference classes? Finally, how can he account for basic features of moral agency? It turns out that the last problem is the most serious one for his account.

1. Here is a very simple game. You come up with a number and I come up with a number. If I come up with the higher number, I win; otherwise you win. You go first. Call this ‘The Very Simple Game’. Few would play it if they had to go first and many if they are guaranteed to go second.2. Here is another one. You come up with a number n and I come up with a number m. If m times 1/ n > 1, then I win; if not, then you win. You go first. Call this ‘Still The Very Simple Game’. Since I win just in case m is greater than n, this game collapses into The Very Simple Game. Few people will play it if they have to go first.3. Here is a third one. Let us call it ‘Looks Like A Tricky Game’. Suppose you have a choice between exactly two actions: keep holding on to some thing t ; hand t over to me and accept my offer to give you, with some probability p , some thing with utility m .Suppose, you are a maximizer of expected utility with …

One of the most interesting accounts of knowledge which have been recently proposed is the safety account of knowledge. According to it, one only knows that p if one's true belief that p could not have easily been false: S believes that p ==> p (where "==>" stands for the subjunctive conditional). This paper presents a counter-example and discusses attempts to fix the problem. It turns out that there is a deeper underlying problem which does not allow for a solution that would help the safety theorist. It is not the case that knowledge is safe.

Kant’s views about the nature and value of enlightenment have been discussed very much since 1784, and without ever losing any of their relevance and importance. I will discuss a topic that has not been discussed quite that extensively: Kant’s conception of enlightenment as it relates to the idea of perfection (Vollkommenheit) in particular. Is the project of enlightenment also a project of perfection (and vice versa), and if yes, in what sense and to what degree? My aim is twofold here: not just to present a sketch of Kant’s views but also to do so in the light of contemporary, systematic questions and ideas concerning the idea of perfection.

There is a very plausible principle of the transitivity of justifying reasons. It says that if "p" is better justified than "q" (all things considered) and "q" better than "r", then "p" is better justified than "r" (all things considered). There is a corresponding principle of rational theory choice. Call one theory "a better theory than" another theory if all criteria of theory choice considered (explanatory power, simplicity, empirical adequacy, etc.), the first theory meets the criteria better than the second theory. The corresponding transitivity principle says that if theory A is a better theory than theory B and if theory B is a better theory than theory C, then A is a better theory than theory C. I argue against this principle. It turns out that whenever there are 2 or more relevant and independent criteria of theory evaluation, and whenever at least of one the criteria is "non-linear" in a certain sense, there may be violations of transitivity which do not violate any standards of rationality (of theory choice). This shows, again, that theory choice cannot be seen as merely the application of given rules of rational theory choice.

The well known Monty Hall-problem has a clear solution if one deals with a long enough series of individual games. However, the situation is different if one switches to probabilities in a single case. This paper presents an argument for Monty Hall situations with two players (not just one, as is usual). It leads to a quite general conclusion: One cannot apply probabilistic considerations (for or against any of the strategies) to isolated single cases. If one does that, one cannot but violate a very plausible non-arbitrariness condition and is led into a Moore-paradoxical incoherence. Even though arguments for switching are correct as applied to series of games, they don’t say anything useful about what rationality demands in a single case.

Practical conflicts pervade human life. Agents have many different desires, goals, and commitments, all of which can come into conflict with each other. How can practical reasoning help to resolve these practical conflicts? In this collection of essays a distinguished roster of philosophers analyse the diverse forms of practical conflict. Their aim is to establish an understanding of the sources of these conflicts, to investigate the challenge they pose to an adequate conception of practical reasoning, and to assess the degree to which that challenge can be met. These essays will serve as a major resource for students of philosophy but will also interest students and professionals in related fields of the social sciences such as psychology, political science, sociology and economics.

Safety accounts of knowledge claim, roughly, that knowledge that p requires that one's belief that p could not have easily been false. Such accounts have been very popular in recent epistemology. However, one serious problem safety accounts have to confront is to explain why certain lottery‐related beliefs are not knowledge, without excluding obvious instances of inductive knowledge. We argue that the significance of this objection has hitherto been underappreciated by proponents of safety. We discuss Duncan Pritchard's recent solution to the problem and argue that it fails. More importantly, the problem reaches deeper and poses a threat to any current safety accounts that require a belief's modal stability in close possibilities (as well as safety accounts that appeal to ‘normality’). We end by arguing that ways out of the problem require substantial reconstruction for a safety‐based account of knowledge.

Most contextualists agree that contexts differ with respect to relevant epistemic standards. In this paper, I discuss the idea that the difference between more modest and stricter standards should be explained in terms of the closeness or remoteness of relevant possible worlds. I argue that there are serious problems with this version of contextualism. In the second part of the paper, I argue for another form of contextualism that has little to do with standards and a lot with the well-known problem of the reference class. This paper also illustrates the fact that contextualism comes in many varieties.
