Today should be a Golden Age for free speech – with technology providing more ways of communicating ideas and opinions than ever before. Yet we’re actually witnessing a growing wave of restrictions on freedom of thought and expression. In Having Your Say a variety of authors – academics, philosophers, comedians and more – stress the fundamental importance of free speech, one of the cornerstones of classical liberalism. And they provide informed and incisive insights on this worrying trend,...

The Metaphysics of Good and Evil is the first, full-length contemporary defence, from the perspective of analytic philosophy, of the Scholastic theory of good and evil – the theory of Aristotle, Augustine, Aquinas, and most medieval and Thomistic philosophers. Goodness is analysed as obedience to nature. Evil is analysed as the privation of goodness. Goodness, surprisingly, is found in the non-living world, but in the living world it takes on a special character....

Should people with deeply held objections to certain practices be allowed to opt out of involvement with them? Should a Christian baker who objects to homosexuality be allowed to deny service to a customer seeking a cake for a gay wedding? Should a Catholic nurse be able to refuse to contribute to the provision of abortions without losing her job? The law increasingly answers no to such questions. But David Oderberg argues that this is a mistake. He contends that in such cases, opting out ...

Real Essentialism presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like – can we define and classify reality? Many if not most philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. Real Essentialism reinvigorates the tradition...

In his long-awaited new edition of Philosophy of Mathematics, James Robert Brown tackles important new as well as enduring questions in the mathematical sciences.

Are experiments of any real value?This clear and engaging book takes a unique approach, encompassing non-standard topics such as the role of visual reasoning, the importance of notation, and the place of ...

In this externality the determinations of the concept have the appearance of an indifferent subsistence and isolation in regards to each other. The concept therefore exists as an inward entity. Hence nature exhibits no freedom in its existence, but only necessity and contingency. For this reason nature, in the determinate existence, which makes it nature, is not to be deified, nor are the sun, moon, animals, plants, and so on, to be regarded and adduced as the works of God, more excellent ...

Ockham's razor, the principle of parsimony, states that simpler theories are better than theories that are more complex. It has a history dating back to Aristotle and it plays an important role in current physics, biology, and psychology. The razor also gets used outside of science - in everyday life and in philosophy. This book evaluates the principle and discusses its many applications. Fascinating examples from different domains provide a rich basis for contemplating the principle's pro...
