Overfitting and Heuristics in Philosophy
"The main aim of this book is to encourage philosophers to take a more sophisticated and scientific attitude to their handling of evidence, both in theory and in practice, by introducing two categories neglected in current metaphilosophy. The first category is that of heuristics. These are typically efficient ways of solving problems of some kind, quick and easy to use, and mostly but not always reliable. Those most probably central to philosophical methodology are more or less humanly universal general cognitive heuristics which we employ without conscious reflection. In many plausible cases, they can be shown to be implicitly inconsistent, and so cannot be perfectly valid, though for evolutionary reasons they are likely to be fairly reliable in normal cases. Such heuristics may well generate false but convincing data as applied to some actual or hypothetical. Arguably, the heuristics also generate philosophical paradoxes, just as heuristics embedded in our perceptual systems generate perceptual illusions. The second category is that of overfitting. This is a recognized pathology in science, when models are allowed to become very complicated to achieve a close fit with data, and further complications typically keep having to be made as new data comes in. When the data contains errors, such theorizing provides little insight. Scientists guard against overfitting by strongly preferring comparatively simple models. Philosophers should learn to do the same. This approach is applied to debates between coarse-grained (intensionalist) and fine-grained (hyperintensionalist) theories of metaphysics, ascriptions of propositional attitudes, and other topics, in favour of intensionalism"--

Noted philosopher Timothy Williamson uses ideas from contemporary psychology and data-driven science to identify defects in how many philosophers arrive at their theories, because they rely on common sense ways of thinking that are correct most but not all the time. When those ways of thinking are pushed too far, what Williamson refers to as overfitting can result in philosophical paradoxes. He shows how philosophers have over-complicated their theories in futile attempts to accommodate erroneous 'data' and he documents these problems in detail through case studies of contemporary philosophy. He also discusses what philosophers can do to avoid these problems. Williamson's important diagnosis and prescription will be of interest to a wide range of philosophers.

Methods and Skills for Philosophy introduces students to methodologies, strategies, heuristics and formal tools which are typically employed in contemporary analytic philosophy. This helpful resource gets the reader to engage with the analytical skills required to master postgraduate studies in philosophy. In conjunction with analysing texts, reflecting on arguments and trying to solve problems, the book will help instil in students the kind of understanding, knowledge and skills they need to succeed at the postgraduate level. More specifically, students will have a better grasp of how to pose a succinct research question and then critically pursue the proposed topic by engaging with relevant literature, reflecting on philosophical presuppositions, selecting suitable argumentative strategies and defending a preferred view against objections. Topics covered include: the nature and character of arguments conceptual analysis analytical truths logic and language models of explanation and reduction strategies and dialectics rational intuitions. Methods and Skills for Philosophy: An Advanced Guide provides a comprehensive and accessible introduction to philosophical methods. It is a must-read for advanced undergraduate or postgraduate students of philosophy, and also suitable for those studying postgraduate philosophy who have a background in other academic disciplines.
