Jonathan Westphal

Jonathan Westphal (born 1951) is a philosopher working on the philosophy of mind, metaphysics, philosophy of science, logic and philosophy of language and aesthetics. He was a pioneer in the philosophy of color. More recently he has become interested in issues in the philosophy of time, and in the understanding of human freedom. In the history of philosophy, he has worked mostly on Wittgenstein and Leibniz. He lives in Eastbourne, East Sussex, and works as a private tutor in philosophy.

Westphal received his BA from Harvard College in 1973, where he was offered tutorials by G.E.L. Owen as a Junior. He received an MA from the University of Sussex in 1975, and the PhD from the University of London 1981, where he studied with David Wiggins. He has taught at the University of Hawaii, the University of London, Idaho State University, Amherst College, Hampshire College and at other colleges and universities in the UK and the US. He has been an Alexander von Humboldt Fellow, Alexander von Humboldt Foundation, at the University of Munich; he is a Fellow of Berkeley College (Yale University), and a Permanent Member of the Senior Common Room at University College, Oxford.

Published works

Among Westphal's one hundred or so publications are:
* 1987
Colour: Some Philosophical Problems from Wittgenstein
'.
* 1991 ''Colour: a Philosophical Introduction'', (Oxford: Blackwell, 1991, 2nd ed) . In this work as in its 1987 predecessor Westphal subjects some of the statements in Wittgenstein's ''Remarks on Colour'' ("the puzzle propositions") to a detailed examination drawing on philosophy, phenomenology, psychology and physics. Rejecting Wittgenstein's grammatical explanation of colours, as well as the physicalists' reduction of colours to light emissions of specific wavelengths, Westphal argues that the puzzle propositions are analytic and that the relevant definitions are to be given in terms of phenomenalistically interpreted absorption spectra. According to WorldCat, the book is in 224 libraries
* 1998 ''Philosophical Propositions: An Introduction to Philosophy'' (London: Routledge, 1998). 169 pp. . According to WorldCat, the book is held in 1206 libraries In this work Westphal presents an introduction to key philosophical problems in chapters titled: The Nature of a Philosophical Problem; Basic Concepts of Logic and Philosophy; the Problem of Evil; the Existence of God; Reality; Certainty; Time; Personal Identity; the Mind-Body Problem; Freewill and Determinism; the Meaning of Life?
*“Leibniz and the Lucky Proof”, in The History of Necessity, ed. Max Cresswell et. al., Cambridge, Cambridge University Press, 2015.
* 2005 "Conflicting Appearances, Necessity and the Irreducibility of Propositions About Colours", ''Proceedings of the Aristotelian Society'' 105 (2):219-235. Reviewing the argument from 'conflicting appearances' for the view that nothing has any one colour, Westphal takes further a well-known criticism of the argument made by Austin and Burnyeat. He aIso undertakes the task of positive construction, offering a theory of what it is that all things coloured a particular colour have in common, and he argues that the resulting "color phenomenalism", rather than physicalism, is required to give a satisfactory account of the necessity of Wittgenstein's 'puzzle propositions' about colour.

(15 pages). Propositional variables ''p'', ''q'', etc., are the unit vectors in a vector space, and various logical relations are represented, e.g. duality is the sliding of a vector through the origin, which produces De Morgan's Theorems.
* 2006 "The Future and the Truth-Value Links: A Common Sense View", ''Analysis'' 66 (289):1–9. This article is about the ancient problem of the truth of propositions about the future, or future contingents. Westphal argues that propositions about the future are true not because anything is now the case but because something ''will be'' the case. The problem is a confusion about tenses.
* 2008 ""My Body", "my X" and "I"" ''American Philosophical Quarterly'', 45 (3):187-197. Sometimes 'My body is ''F'' follows from 'I am ''F'', for example when ''F'' is "hot", but sometimes not, for example when ''F'' is "rich". Westphal offers a theory of the logical relations between "mind", "body", and "I" which gives a complete symmetry between mind and body.
* 2011 "Silhouettes Are Shadows", ''Acta Analytica'' 26 2:187-197. Here a solution is proposed to Sorensen’s problem about the eclipse of Near and Far. Since a silhouette is a shadow, what is seen is the silhouette or shadow of Far, into which Near has disappeared, as a smaller object might. Shadows are seen because the surface in shadow fails to reflect light.
*2005, “Leibniz and the Lucky Proof”, in ''The History of Necessity'', ed. Max Cresswell et. al., Cambridge, Cambridge University Press.
*2016 ''The Mind-Body Problem'', (Cambridge MA: MIT Press, 2016) argues for a neutral monist solution to the mind-body problem, and claims that in the past neutral monists have paid almost no attention to the causal relations between mind and body.
*2020 "Leibniz’s Proof of the Principle of Sufficient Reason from Considerations concerning Necessary and Sufficient Conditions”, ''Studia Leibnitiana'', 229-241.
*2022 "Elements of the Philosophy of 'Right'", ''Philosophical Investigations'': 1-8. The argument of the paper is that there are four main senses of ''right''. The two ethical ones ("according with a rule" and "appropriate") apply in exactly the same sense to ethical and non-ethical applications. "The right tool", for example, is one that does its job in the context of a set of requirements, and in so doing is the appropriate tool.
