Summary: According to the currently accepted model in cosmology, our universe is made up of 5% of ordinary matter, 25% cold dark matter, and 70% dark energy. But what kind of entities are dark matter and dark energy? This chapter asks what the evidence for these entities is and which rival theories are currently available. This provides with an opportunity to explore a well-known philosophical problem known as under-determination of theory by evidence.
The origins of the universe: laws, testability and observability in cosmology
Summary: How did our universe form and evolve? Was there really a Big Bang, and what came before it? This chapter takes the reader through the history of contemporary cosmology and looks at how scientists arrived at the current understanding of our universe. It explores the history of astronomy, with the nebular hypothesis back in the eighteenth century, and in more recent times, Einstein’s general relativity and the ensuing cosmological models. Finally, it explains the current Standard Model and early universe cosmology as well as the experimental evidence behind it.
The Status of Consciousness in Nature
The Mental and The Physical
Summary: In this paper the author addresses physicalism and the problem of whether physicalism can account for consciousness and intentionality of our mental states. After providing a good survey of problems posed by this phenomenon as well as possible physicalist responses, she concludes that there still is no satisfying explanation of how the nature of our mental states fits into an “otherwise physical world”.
Semantic Externalism and Psychological Externalism
Abstract: Externalism is widely endorsed within contemporary philosophy of mind and language. Despite this, it is far from clear how the externalist thesis should be construed and, indeed, why we should accept it. In this entry I distinguish and examine three central types of externalism: what I call foundational externalism, externalist semantics, and psychological externalism. I suggest that the most plausible version of externalism is not in fact a very radical thesis and does not have any terribly interesting implications for philosophy of mind, whereas the more radical and interesting versions of externalism are quite difficult to support.
Why We Don’t Deserve Credit for Everything We Know
Abstract: A view of knowledge – what I call the Deserving Credit View of Knowledge (DCVK) – found in much of the recent epistemological literature, particularly among so-called virtue epistemologists, centres around the thesis that knowledge is something for which a subject deserves credit. Indeed, this is said to be the central difference between those true beliefs that qualify as knowledge and those that are true merely by luck – the former, unlike the latter, are achievements of the subject and are thereby creditable to her. Moreover, it is often further noted that deserving credit is what explains the additional value that knowledge has over merely lucky true belief. In this paper, I argue that the general conception of knowledge found in the DCVK is fundamentally incorrect. In particular, I show that deserving credit cannot be what distinguishes knowledge from merely lucky true belief since knowledge is not something for which a subject always deserves credit.
Epistemic Injustice: Power and the Ethics of Knowing
Publisher’s Note: In this exploration of new territory between ethics and epistemology, Miranda Fricker argues that there is a distinctively epistemic type of injustice, in which someone is wronged specifically in their capacity as a knower. Justice is one of the oldest and most central themes in philosophy, but in order to reveal the ethical dimension of our epistemic practices the focus must shift to injustice. Fricker adjusts the philosophical lens so that we see through to the negative space that is epistemic injustice. The book explores two different types of epistemic injustice, each driven by a form of prejudice, and from this exploration comes a positive account of two corrective ethical-intellectual virtues. The characterization of these phenomena casts light on many issues, such as social power, prejudice, virtue, and the genealogy of knowledge, and it proposes a virtue epistemological account of testimony. In this ground-breaking book, the entanglements of reason and social power are traced in a new way, to reveal the different forms of epistemic injustice and their place in the broad pattern of social injustice.
Rational Authority and Social Power: Toward a Truly Social Epistemology
Abstract: This paper explores the relation between rational authority and social power, proceeding by way of a philosophical genealogy derived from Edward Craig’s Knowledge and the State of Nature. The position advocated avoids the errors both of the ‘traditionalist’ (who regards the socio-political as irrelevant to epistemology) and of the ‘reductivist’ (who regards reason as just another form of social power). The argument is that a norm of credibility governs epistemic practice in the state of nature, which, when socially manifested, is likely to imitate the structures of social power. A phenomenon of epistemic injustice is explained, and the politicizing implication for epistemology educed.
The Search for the Source of the Epistemic Good
Abstract: Knowledge has almost always been treated as good, better than mere true belief, but it is remarkably difficult to explain what it is about knowledge that makes it better. I call this “the value problem.” I have previously argued that most forms of reliabilism cannot handle the value problem. In this article I argue that the value problem is more general than a problem for reliabilism, infecting a host of different theories, including some that are internalist. An additional problem is that not all instances of true belief seem to be good on balance, so even if a given instance of knowing p is better than merely truly believing p, not all instances of knowing will be good enough to explain why knowledge has received so much attention in the history of philosophy. The article aims to answer two questions: What makes knowingp better than merely truly believing p? The answer involves an exploration of the connection between believing and the agency of the knower. Knowing is an act in which the knower gets credit for achieving truth. What makes some instances of knowing good enough to make the investigation of knowledge worthy of so much attention? The answer involves the connection between the good of believing truths of certain kinds and a good life. In the best kinds of knowing, the knower not only gets credit for getting the truth but also gets credit for getting a desirable truth. The kind of value that makes knowledge a fitting object of extensive philosophical inquiry is not independent of moral value and the wider values of a good life.
What can we know a priori?
Abstract: Michael Devitt has been developing an influential two-pronged attack on the a priori for over thirteen years. This attack does not attempt to undermine the coherence or significance of the distinction between the a priori and the a posteriori, but rather to answer the question: ‘What Can We Know A Priori?’ with: ‘Nothing’. In this paper I explain why I am dissatisfied with key extant responses to Devitt’s attack, and then take my own steps towards resisting the attack as it appears in two recent incarnations. Devitt aims firstly to undermine the motivation for believing in any a priori knowledge, and secondly to provide reasons directly against believing in any. I argue that he misidentifies the motivations available to the a priorist, and that his reasons against believing in the a priori do not take account of all the options. I also argue that his attempt to combine the two prongs of the attack into an abductive argument for his anti-a priorist position does not succeed.
