This comprehensive textbook provides a clear nontechnical introduction to the philosophy of science. Through asking whether science can provide us with objective knowledge of the world, the book provides a thorough and accessible guide to the key thinkers and debates that define the field. George Couvalis surveys traditional themes around theory and observation, induction, probability, falsification and rationality as well as more recent challenges to objectivity including relativistic, feminist and sociological readings. This provides a helpful framework in which to locate (...) the key intellectual contributions to these debates, ranging from those of Mill and Hume, through Popper and Kuhn to Laudan, Bloor and Garfinkel among.

Aristotle explains existence through postulating essences that are intrinsic and percep- tion independent. I argue that his theory is more plausible than Hume’s and Russell’s theories of existence. Russell modifies Hume’s theory because he wants to allow for the existence of mathematical objects. However, Russell’s theory facilitates a problematic collapse of ontology into epistemology, which has become a feature of much analytic philosophy. This collapse obscures the nature of truth. Aristotle is to be praised for starting with a clear account (...) of ordinary objects rather than immediately reifying mathematical objects. He thus allows us to have a coherent account of existence and truth, and to easily resist collapsing ontology into epistemology. (shrink)

The eighteenth century philosopher David Hume was much influenced by Greek philosophy and literature. His favourite writer was the satirist Lucian. What is David Hume’s thanatotherapy (therapy of the fear of death)? Is he an Epicurean or Pyrrhonian thanatotherapist? I argue that, while he is in part an Epicurean who is sceptical about his Epicureanism, he is primarily a Lucianic thanatotherapist. A Lucianic thanatotherapist uses self and other deprecating irony as a form of therapy. He also ruthlessly satirises religious consolations. (...) I use Hume’s deathbed allusions to Lucian’s Kataplous (floating downwards) and the Dialogues of the Dead to explain my view. (shrink)

Aristotle and William of Ockham both argue that existence or being is a predicate, though not a distinguishing predicate. I place Ockham’s argument in an Aristotelian context and discuss its merits. I then turn to empiricist criticisms of the view that we can coherently predicate being of things. I argue that while Ockham’s argument is cogent, his account of how we come to have the concept of being is inadequate. Ockham’s view needs to be supplemented with Kantian insights.

Aristotle argues that provided we have moderate luck, we can attain eudaimonia through our own effort. He claims that it is crucial to attaining eudaimonia that we aim at an overall target in our lives to which all our actions are directed. He also claims that the proper target of a eudaimon human life is virtuous activity, which is a result of effort not chance. He criticises Theognis for saying that the most pleasant thing is to chance on love, arguing (...) instead that virtuous activity is the most pleasant thing. I argue that although Aristotle’s view is insightful and carefully worked out, he fails to show that Theognis is wrong. Effort is not necessarily the path to human eudaimonia and important things we attain by chance seem to have an irreplacable value. (shrink)

Most philosophers hold that the use of our deductive powers confers an especially strong warrant on some of our mathematical and logical beliefs. By contrast, many of the same philosophers hold that it is a matter of serious debate whether any inductive inferences are cogent. That is, they hold that we might well have no warrant for inductively licensed beliefs, such as generalizations. I argue that we cannot know that we know logical and mathemati- cal truths unless we use induction. (...) Our confidence in our logical and mathematical powers is not justified if we are inductive scep- tics. This means that inductive scepticism leads to a deductive scep- ticism. I conclude that we should either be philosophical sceptics about our knowledge of deduction and induction, or accept that some of our inductive inferences are cogent. (shrink)
