For Moore, it is a paradox that although I would be absurd in asserting that (it is raining but I don.

Foley and Turri have recently given objections to the defeasibility theory of propositional knowledge. Here, I give an objection of a quite different stripe by looking at what the theory must say about knowing that you know. I end with some remarks on how this objection relates to rival theories and how this might be a worry for some of these.

I objected that the defeasibility theory of knowledge prohibits you from knowing that you know that p if your knowledge that p is a posteriori. Rodrigo Borges claims that Peter Klein has already satisfactorily answered a version of my objection. He attempts to defend Klein’s reply and argues that my objection fails because a principle on which it is based is false.I will show that my objection is not a version of the old one that Klein attempts (unsuccessfully) to address, (...) that Borges’ defence of Klein’s reply fails and that his argument against my new objection leaves it untouched.

The book aims at equipping you with 21st Century Skills key life skills that will drive your future employability, promotion and career success. These are required for effective reasoning, writing and decision-making in changing, evolving environments. You give reasons for what you do and think every day. You argue. You often argue about things that matter to you. For example you might argue that you are the best candidate for promotion, about whether your company should invest in China, about the (...) best way to help a friend or about what the right thing to do is in an ethical dilemma. The list is up to you. If you work your way carefully through this book you will become better at reasoning both in terms of understanding and clarifying other peoples’ arguments and also at producing increasingly sophisticated and compelling arguments of your own. You will learn how to recognize common but often seductive mistakes in reasoning and so be empowered to avoid making these mistakes yourself. Your writing and oral presentations will improve and you will hone your ability to define crucial terms in argument, debate and discussion. As this book is specifically written with everyday language considerations in mind, it is a valuable tool for anyone to understand, evaluate and construct arguments in ordinary language. (shrink)

Doxastic logic, beginning with Hintikka’s Knowledge and Belief. An Introduction to the Logic of the Two Notions, studies relations between propositions about what we believe. Using ‘a’ as a proper name like ‘Ann’, ‘→’ for ‘if’ as opposed to material implication, propositional variables such as ‘p’, ‘q’ and ‘B’ to represent the two-place relation, ‘... believes that... ’.

Neil Sinhababu and I presented Backward Clock, an original counterexample to Robert Nozick’s truth-tracking analysis of propositional knowledge. In their latest defence of the truth-tracking theories, “Methods Matter: Beating the Backward Clock,” Fred Adams, John A. Barker and Murray Clarke try again to defend Nozick’s and Fred Dretske’s early analysis of propositional knowledge against Backward Clock. They allege failure of truth-adherence, mistakes on my part about methods, and appeal to charity, ‘equivocation,’ reliable methods and unfair internalism. I argue that these (...) objections all fail. They are still stuck with the fact that the tracking theories fall to Backward Clock, an even more useful test case for other analyses of knowledge than might have first appeared. (shrink)
