    Notes on Logic and Set Theory.P. T. Johnstone - 1987 - Cambridge University Press.
    A succinct introduction to mathematical logic and set theory, which together form the foundations for the rigorous development of mathematics. Suitable for all introductory mathematics undergraduates, Notes on Logic and Set Theory covers the basic concepts of logic: first-order logic, consistency, and the completeness theorem, before introducing the reader to the fundamentals of axiomatic set theory. Successive chapters examine the recursive functions, the axiom of choice, ordinal and cardinal arithmetic, and the incompleteness theorems. Dr. Johnstone has included numerous exercises (...)

    Finitary Sketches.J. Adámek, P. T. Johnstone, J. A. Makowsky & J. Rosický - 1997 - Journal of Symbolic Logic 62 (3):699-707.
    Finitary sketches, i.e., sketches with finite-limit and finite-colimit specifications, are proved to be as strong as geometric sketches, i.e., sketches with finite-limit and arbitrary colimit specifications. Categories sketchable by such sketches are fully characterized in the infinitary first-order logic: they are axiomatizable by σ-coherent theories, i.e., basic theories using finite conjunctions, countable disjunctions, and finite quantifications. The latter result is absolute; the equivalence of geometric and finitary sketches requires (in fact, is equivalent to) the non-existence of measurable cardinals.

    Unintended Changes in Cognition, Mood, and Behavior Arising From Cell-Based Interventions for Neurological Conditions: Ethical Challenges.P. S. Duggan, A. W. Siegel, D. M. Blass, H. Bok, J. T.

    The prospect of using cell-based interventions to treat neurological conditions raises several important ethical and policy questions. In this target article, we focus on issues related to the unique constellation of traits that characterize CBIs targeted at the central nervous system. In particular, there is at least a theoretical prospect that these cells will alter the recipients' cognition, mood, and behavior—brain functions that are central to our concept of the self. The potential for such changes, although perhaps remote, is cause (...)

    Complemented Sublocales and Open Maps.Peter T. Johnstone - 2006 - Annals of Pure and Applied Logic 137 (1-3):240-255.
    We show that a morphism of locales is open if and only if all its pullbacks are skeletal in the sense of [P.T. Johnstone, Factorization theorems for geometric morphisms, II, in: Categorical Aspects of Topology and Analysis, in: Lecture Notes in Math., vol. 915, Springer-Verlag, 1982, pp. 216–233], i.e. pulling back along them preserves denseness of sublocales . This result may be viewed as the ‘dual’ of the well-known characterization of proper maps as those which are stably closed. We (...)

    Omnipotence: P. T. Geach.P. T. Geach - 1973 - Philosophy 48 (183):7-20.
    It is fortunate for my purposes that English has the two words ‘almighty’ and ‘omnipotent’, and that apart from any stipulation by me the words have rather different associations and suggestions. ‘Almighty’ is the familiar word that comes in the creeds of the Church; ‘omnipotent’ is at home rather in formal theological discussions and controversies, e.g. about miracles and about the problem of evil. ‘Almighty’ derives by way of Latin ‘omnipotens’ from the Greek word ‘ pantokratōr ’; and both this (...)

    On Teaching Logic: P. T. Geach.P. T. Geach - 1979 - Philosophy 54 (207):5-17.
    In medieval writers an important distinction was drawn between two applications of the term ‘ logica ’: there was logica utens , the practice of thinking logically about this or that subject-matter, and there was logica docens , the construction of logical theory. Of course the English word ‘logic’ and its derivative ‘logical’ have a corresponding twofold meaning, and we ignore the distinction at the risk of serious confusion. ‘Logical thought’ may mean thinking that is being commended as orderly, consistent, (...)

    Spinoza and the Divine Attributes: P. T. Geach.P. T. Geach - 1971 - Royal Institute of Philosophy Supplement 5:15-27.
    On the very first page of Spinoza's Ethics we find the perplexing definition of ‘attribute’: ‘By an attribute I mean what the understanding perceives in regard to a substance as constituting its essence’. Each attribute of a substance by itself thus constitutes the essence of a substance; if there are many attributes of the same substance, it does not take all of them together to constitute its essence. Spinoza, as we all know, in fact held that there is only one (...)

    The Euthyphro might well be given to undergraduates to read early in their philosophical training. The arguments are apparently simple, but some of them, as I shall show, lead naturally on to thorny problems of modern philosophy. Another benefit that could be gained from reading the Euthyphro is that the reader may learn to be forewarned against some common fallacies and debating tricks in moral disputes.

    Topos Theory is an important branch of mathematical logic of interest to theoretical computer scientists, logicians and philosophers who study the foundations of mathematics, and to those working in differential geometry and continuum physics. This compendium contains material that was previously available only in specialist journals. This is likely to become the standard reference work for all those interested in the subject.

    What makes it hard to dance? Twentieth-century phenomenologists drew attention to the importance of the lived body, and dance is the art form for which the lived body is literally central. Why then isn’t dance the easiest art form to engage in? Phenomenologists are drawn to situations where a phenomenon breaks down, which can open insights into the phenomenon itself. Here the phenomenon is the ability to dance where one might normally expect to. This paper invokes Marion Milner’s book On (...)
