Knowledge and Reality

The purpose of this subject is to enable you to examine some central questions about the nature of the world and the extent to which we can have knowledge of it.

In considering knowledge you will examine whether it is possible to attain knowledge of what the world is really like. Is our knowledge of the world necessarily limited to what we can observe to be the case? Indeed, are even our observational beliefs about the world around us justified? Can we have knowledge of what will happen based on what has happened? Is our understanding of the world necessarily limited to what we can prove to be the case? Or can we understand claims about the remote past or distant future which we cannot in principle prove to be true?

In considering reality you will focus on questions such as the following. Does the world really contain the three-dimensional objects and their properties - such as red buses or black horses - which we appear to encounter in everyday life? Or is it made up rather of the somewhat different entities studied by science, such as colourless atoms or four-dimensional space-time worms? What is the relation between the common sense picture of the world and that provided by contemporary science? Is it correct to think of the objects and their properties that make up the world as being what they are independently of our preferred ways of dividing up reality? These issues are discussed with reference to a variety of specific questions such as ‘What is time?’, ‘What is the nature of causation?’, and ‘What are substances?’ The examination paper also contains a number of optional questions in Philosophy of Science concerning the nature of scientific explanation and scientific method. There is an opportunity in this subject to study such topics as reference, truth and definition, but candidates taking 102 and 108 should avoid repetition of material across examinations, though it is safe to assume that good answers to questions would not involve repetition for which you might be penalised.
