What does it mean to trust the results of a computer simulation? This paper argues that trust in simulations should be grounded in empirical evidence, good engineering practice, and established theoretical principles. Without these constraints, computer simulation risks becoming little more than speculation. We argue against two prominent positions in the epistemology of computer simulation and defend a conservative view that emphasizes the difference between the norms governing scientific investigation and those governing ordinary epistemic practices.

My aim in this paper is to articulate further what may be called an agency theory of self-knowledge. Many theorists have stressed how important agency is to self- knowledge, and much work has been done drawing connections between the two notions.² However, it has not always been clear what _epistemic_ advantage agency gives us in this area and why it does so. I take it as a constraint on an adequate account of how a subject knows her own mental states (...) and acts, that it construe the known mental states and acts realistically and as independent of their self-ascription, and that it deliver genuine epistemic standing to the knower. The main task of the paper will, then, be to explore how our having rational agency with respect to our mental states may be able to secure genuine epistemic warrant for our self-ascriptions of states or acts independent of the ascriptions. This task will be carried out by focussing on the question of what account we should give of our knowledge of what I call our acts of judging. In the remainder of this section, I will do a little to clarify what is meant by that question. Section 2 will attempt to introduce us to elements of the best way to approach the question by considering some alternative strategies. Section 3 is devoted to forming some idea of what _kind_ of warrant we are looking for when considering how agency might give us self-knowledge. Section 4 aims to present a suggestion as to how agency gives us the kind of warrant identified over our acts of judging. Section 5 deals with some objections. (shrink)

This thesis is, in part, a defence of a broad-based approach to epistemology. We should be wary of taking too narrow a focus and thus neglecting important aspects of knowledge. If we are too focused on one methodology then we are likely to miss insights that can come about from a different perspective. With this in mind, I investigate two particular methodologies in detail: Kornblith’s naturalism and Craig’s ‘genealogical’ approach. Kornblith emphasises the importance of looking at knowledge in the context (...) of the natural world, thus stressing the continuity between animal and human knowledge. Craig, on the other hand, focuses on a distinctly human aspect of knowledge: the importance of enquiry and the sharing of information. As such, the two theories of knowledge that are developed have different emphases. I argue that by bringing them together we can better understand what knowledge is. This leads us to the other main contribution of this thesis, which is a defence of the role of reflection in epistemology. This has often been neglected in contemporary epistemology, primarily because of the effectiveness of externalist theories of knowledge. The focus on externalism has lead to reflection being sidelined. I do not argue that reflection is necessary for knowledge, but rather want to bring back attention to the important role that it plays in human life. Reflectively accessible justification is necessary for our knowledge claims and therefore plays a vital role in enquiry. If we add reflectively accessible justification to knowledge then it is both more stable and more valuable. Even if it is not necessary for knowledge, reflection should not be neglected. (shrink)

What is the epistemological role of speech perception in comprehension? More precisely, what is its role in episodes or states of comprehension able to mediate the communication of knowledge? One answer, developed in recent work by Tyler Burge, has it that its role may be limited to triggering mobilizations of the understanding. I argue that, while there is much to be said for such a view, it should not be accepted. I present an alternative account, on which episodes of comprehension (...) are better able to underwrite the interpersonal transmission of knowledge. (shrink)

El objetivo de este trabajo consiste en presentar una forma de conservadurismo epistémico que sea integral, y que sostiene lo siguiente: a partir de que S cree que p, como respuesta exitosa a su entorno, p adquiere un estatus epistémico favorable por el cual es racional que la creencia se mantenga hasta que aparezcan evidencias superadoras que sean alternativas e incompatibles con p. Además, se indagará en desarrollos posibles que puedan hacer de la versión integral un principio prometedor y a (...) la vez plausible, para concluir que otorga racionalidad a nuestros compromisos doxásticos mediante la constante mejora de las habilidades cognitivas.
