Lisa Bortolotti

An Introduction to the Philosophy of Science provides a lively and accessible introduction to current key issues and debates in this area. The classic philosophical questions about methodology, progress, rationality and reality are addressed by reference to examples from the full range of natural and social sciences. Lisa Bortolotti uses a historically-informed perspective on the evolution of science and includes a thorough discussion of the ethical implications of scientific research. Special attention is paid to the complex relationship between the advancement of science, policy making and public interest and to the continuity between scientific research and other human activities. The book is designed to help students think for themselves about the issues identified above, and includes information tables and questions for further reflection to support all stages of the teaching and learning experience, from the comprehension of primary and other secondary texts to debate and essay writing. It also includes a thematic bibliography and a glossary of technical terms. An Introduction to the Philosophy of Science is an excellent introduction to philosophy for students and provides researchers of scientific disciplines with an opportunity to reflect upon the value and impact of their work. It is also a stimulating read for anybody who is interested in the philosophical issues raised by the status of scientific knowledge, the practice of science and the role of experts in contemporary society.

In philosophy, psychiatry, and cognitive science, definitions of clinical delusions are not based on the mechanisms responsible for the formation of delusions. Some of the defining features of delusions are epistemic and focus on whether delusions are true, justified, or rational, as in the definition of delusions as fixed beliefs that are badly supported by evidence). Other defining features of delusions are psychological and they focus on whether delusions are harmful, as in the definition of delusions as beliefs that disrupt good functioning. Even if the epistemic features go some way towards capturing what otherwise different instances of clinical delusions have in common, they do not succeed in distinguishing delusions as a clinical phenomenon from everyday irrational beliefs. Focusing on the psychological features is a more promising way to mark the difference between clinical and non-clinical irrational beliefs, but there is wide variability in the extent to which delusions are psychologically harmful, and some everyday irrational beliefs can affect functioning in similarly negative ways. In this chapter we consider three types of belief that share similar epistemic features and exhibit variation with respect to how psychologically harmful they are: (1) delusions of thought insertion, (2) alien abduction beliefs, and (3) self-enhancing beliefs. In the light of the similarities and differences between these cases, we highlight the difficulty in providing an answer to what makes an irrational belief delusional.

In this paper we address Bernard Williams' argument for the undesirability of immortality. Williams argues that unavoidable and pervasive boredom would characterise the immortal life of an individual with unchanging categorical desires. We resist this conclusion on the basis of the distinction between habitual and situational boredom and a psychologically realistic account of significant factors in the formation of boredom. We conclude that Williams has offered no persuasive argument for the necessity of boredom in the immortal life. 1.
