Michael Potter
Michael Potter is Professor of Logic in the Philosophy Faculty at Cambridge University. He has been a Fellow of Fitzwilliam College since 1989. He was previously at Oxford, where he took a D.Phil. in pure mathematics and was a Fellow of Balliol College. He spent periods of research leave in the Department of Logic and Metaphysics at St Andrews and the Department of Philosophy at Harvard. In 2004 and 2005 he was on research leave from Cambridge as a Senior Research Fellow at Stirling University funded by the AHRC.
His research interests lie mainly in the history of analytic philosophy (Wittgenstein, Russell and Frege), the philosophy of mathematics, and philosophical logic.

This is a German translation (by Achim Wittmüss) of the following. 
Sets: An Introduction, Oxford: Clarendon Press, 1990
A presentation of set theory intended for beginning graduate students. Innovative principally because of its use of a simplified and significantly weaker version of Dana Scott's very intuitive axiom system for set theory. Now almost wholly supplanted by Set Theory and its Philosophy (which was originally conceived as a second edition of it).

A discussion of the philosophical prospects for basing a neoFregean theory of classes on a principle that attempts to articulate the limitationofsize conception.  
The logic of the Tractatus.
In Dov M. Gabbay and John Woods (eds), Handbook of the History of Logic, vol. 5 (NorthHolland, 2009), pp. 255304
Describes some of the main features of the logic and metaphysics of Wittgenstein's Tractatus.  
The birth of analytic philosophy.
In Dermot Moran (ed), The Routledge Companion to Twentieth Century Philosophy (Routledge, 2008), pp. 6092
Tries to identify some strands in the birth of analytic philosophy and to identify in consequence some of its distinctive features.  
What is the problem of mathematical knowledge?
In Mary Leng, Alexander Paseau and Michael Potter (eds), Mathematical Knowledge (OUP, 2007), 1632
Suggests that the recent emphasis on Benacerraf's access problem locates the peculiarity of mathematical knowledge in the wrong place. Instead we should focus on the sense in which mathematical concepts are or might be "armchair concepts" — concepts about which nontrivial knowledge is obtainable a priori.  
Ramsey's transcendental argument.
In Hallvard Lillehammer and D. H. Mellor (eds), Ramsey's Legacy (OUP, 2005), 7182
Explores the historical and philosophical background to a curious argument of Ramsey's that in the Tractatus the possibility of the infinite proves its actuality.  
(With Peter Sullivan)
What is wrong with abstraction?
Philosophia Mathematica, 13 (2005) 18793
We correct a misunderstanding by Hale and Wright of an objection we raised in 'Hale on Caesar' to their abstractionist programme for rehabilitating logicism in the foundations of mathematics.  
(With Timothy Smiley)
Recarving content: Hale's final proposal.
Proceedings of the Aristotelian Society, 102 (2002) 3514
A followup, showing why Bob Hale's revision of his notion of weak sense is still inadequate.  
(With Timothy Smiley)
Abstraction by recarving.
Proceedings of the Aristotelian Society, 101 (2001), 32738
Explains why Bob Hale's proposed notion of weak sense cannot explain the analyticity of Hume's principle as he claims. Argues that no other notion of the sort Hale wants could do the job either.  
Was Gödel a Gödelian platonist?
Philosophia Mathematica, 9 (2001) 33146
Gödel's appeal to mathematical intuition to ground our grasp of the axioms of set theory is notorious. I extract from his writings an account of this form of intuition which distinguishes it from the metaphorical platonism of which Gödel is sometimes accused and brings out the similarities between Gödel's views and Dummett's. [Reviews: Zbl 1007.01017, MR 2002g:01014]  
Intuition and reflection in arithmetic. Arist. Soc. Supp. Vol., 73 (1999) 6373
Classifies accounts of arithmetic into four sorts according to the resources they appeal to in constructing its subject matter.  
Classical arithmetic as part of intuitionistic arithmetic.
Grazer Philosophische Studien, 55 (1998) 12741
Argues that classical arithmetic can be viewed as a proper part of intuitionistic arithmetic. Suggests that this largely neutralizes Dummett's argument for intuitionism in the case of arithmetic.

Taming the infinite.
British Journal of Philosophy of Science, 47 (1996), 60919

Critical notice of `Parts of classes' by David Lewis.
The Philosophical Quarterly, 43 (1993), 362366
Argues that Lewis is not as ontologically innocent as he pretends.  
The metalinguistic perspective in mathematics. Acta Analytica, 11 (1993), 7986
Tries to find a common source for several wellknown paradoxes in mathematics  Skolem's paradox, the permutation argument, and Russell's paradox.  
Infinite coincidences and inaccessible truths. In Philosophy of Mathematics,
Proceedings of the 15th International Wittgenstein Symposium, Vol. 1
(Vienna: HölderPichlerTempsky, 1993), 30713
Argues, contra Dummett, that the platonist need not be any more committed than the intuitionist to the notion that there are arithmetical truths in principle inaccessible to any finite intelligence.  
Iterative set theory. The Philosophical Quarterly, 43 (1993), 17893
Discusses the metaphysics of the iterative conception of set.

12 July 2010, 11am  12pmThe axiom of reducibility in Principia can be thought of as a class existence axiom. Yet class terms are incomplete symbols which disappear on analysis. I shall discuss the interaction between these two features of the system and relate them to later critcisims of Principia by Wittgenstein and Ramsey.
