Sydney Shoemaker has attempted to save mental causation by a new account of realization. As Brian McLaughlin argues convincingly, the account has to face two major problems. First, realization does not guarantee entailment. So even if mental properties are realized by physical properties, they need not be entailed by them. This is the first, rather general metaphysical problem. A second problem, which relates more directly to mental causation is that Shoemaker must appeal to some kind of proportionality as a constraint on causation in order to avoid redundant mental causation. I argue that, in addition, a “piling problem” arises, since causal powers seem to be bestowed twice. Then, I try to sketch an alternative view of the relation between causal powers and properties—a reductionist view—which fares better on some accounts. But it may have to face another and, perhaps, serious problem, the “problem of the natural unity of properties”. Finally, I will pose a question about the relation between causal powers and causation.

Recently, some philosophers have claimed that consciousness has an important epistemological role to play in the introspective self-ascription of one’s own mental states. This is the thesis of the epistemological role of consciousness for introspective self-knowledge. I will criticize BonJour’s account of the role of consciousness for introspection. He does not provide any reason for believing that conscious states are epistemically better off than non-conscious states. Then I will sketch a representationalist account of how the thesis could be true. Conscious states are available to the subject in a very special way in which non-conscious states are not available. This is the first part of the explanation. The crucial further element in the representationalist account is what I would like to call the ‘introspective mode of mind’. A mind can operate in certain ways or modes – modes of mind. Introspection normally takes place in the introspective mode of mind, judgments about one’s environment in the mode of ‘taking one’s appearances at face value’. And there probably are other modes of mind. The introspective mode of mind is characterized by the special way or framework in which cognitive capacities are employed

Plato’s Meno problem is the problem of why knowledge is better than true belief which is not knowledge. The paper studies the account of this surplus value of knowledge that recent reliabilist virtue epistemologists like John Greco and Ernest Sosa have proposed: knowledge is true belief from epistemic virtue. I reconstruct the master argument which subsumes the epistemic case under the general case of success from virtue. Five accounts of virtue are presented and discussed critically. The result is that only the fifth account – the refined dispositionalist account of virtue, based on an idea of J.J. Thomson – is viable, for the purposes of accounting for the surplus value of knowledge along the lines of the master argument. However, there is at least one remaining question, namely, of why success from virtue has surplus value in general

I distinguish between three kinds of reliabilism for epistemic justification, namely, pure reliabilism, evidential reliabilism, and reasons reliabilism, and I argue for reasons reliabilism. Pure reliabilism and evidential reliabilism are plagued, most importantly, by the generality problem, and they cannot deal adequately with defeater phenomena. One can avoid these problems only by jettisoning the idea of process reliability. The truth connection ? which is essential for any kind of reliabilism ? has to be provided in an altogether different way, namely, by means of facts in the world which serve as objective reasons (or evidence). So, as reasons reliabilism says, a justified belief has to be anchored in an objective reason which speaks in favor of its truth. Only in this way can intuitions about defeaters be preserved and explained. And reasons reliabilism can avoid the generality problem

The idea of truthmakers is important for doing serious metaphysics, since a truthmaker principle can give us important guidance in finding out what we would like to include into our ontology. Recently, David Lewis has argued against Armstrong’s argument that a plausible truthmaker principle requires us to accept facts. I would like to take a close look at the argument. I will argue in detail that the Humean principle of recombination on which Lewis relies is not plausible (independently of the issue of facts). Then I will show that the right truthmaker principle that vindicates facts is superior to the modified truthmaker principle that Lewis has proposed. This will lead into the topic of being and existence. It turns out that truthmaking and facts are plausible, well suited for one another, and very coherent with a plausible conception of being.

The paper is an investigation into the prospects of an epistemology of non-conceptual knowledge. According to the orthodox view, knowledge requires concepts and belief. I present several arguments to the effect that there is non-conceptual, non-doxastic knowledge, the obvious candidate for such knowledge being non-conceptual perception. Non-conceptual perception seems to be allowed for by cognitive scientists and it exhibits the central role features of knowledge—it plays the knowledge role: it respects an anti-luck condition, it is an achievement, it enables one to act for a reason, and it provides justification. Furthermore, it makes a straightforward and elegant explanation of perceptual knowledge possible: doxastic perceptual knowledge builds on non-conceptual perception as non-conceptual knowledge. Three objections that might naturally arise will be discussed and answered. Thus, the prospects of an epistemology without belief seem to be much better than the orthodoxy wants to have it. We can extend knowledge into the non-conceptual realm

I will present a problem for any externalist evidentialism that allows for accidental possession of evidence. There are Gettier cases for justification. I will describe two such cases – cases involving veridical hallucination. An analysis of the cases is given, along the lines of virtue epistemology . The cases show that certain externalist evidentialist accounts of justification do not provide sufficient conditions. The reason lies in the fact that one can be luckily in possession of evidence, and then one will not have a justified belief. Justified belief requires an anti-luck condition on possession of evidence. This opens up the prospects of a unified virtue-epistemology covering both knowledge and justification
