That time and place were the late 1940s in Oxford, at the beginning of the diverse, productive and lengthy career of Peter Strawson, whose accomplishments clearly place him at the forefront of Anglophone philosophers in the latter half of the twentieth century. The questions that engaged him at the outset concern our common use of expressions to refer to particular persons and things as the fundamental objects of reference. That use is fundamental, but since anything whatsoever can be identifyingly referred to, the individuals of our discourse will include not only particular objects, but also all manner of concepts, such as those of species, qualities and relations. This linguistic use is indeed common but, on Strawson's own account, an attentive investigation of what that presupposes leads us straightaway not only to the most fundamental questions of logic, but also to those of ontology and epistemology.

It is remarkable that while the theme of singular reference and predication, and their objects, has been consistently central to his work, that one theme has at the same time given entry to a broad world of descriptive metaphysics, and to a consequent fresh and critical view of contemporary scepticism and naturalism.
