The object of this paper is, as the title implies, to investigate the relation of Plato’s thought to natural science. More especially, it is intended to examine the widely held view that Plato’s influence, owing to the character of his beliefs, was necessarily and positively unfavourable to the development of natural science, as we know it at the present day.

This paper outlines an analysis of the word ‘fun’, as it is used in everyday English sentences to describe various activities and asks why some things are labeled as fun while others seem unable to be properly described as such. One common unspoken idea, for example, is that a fun activity is deemed fun due to having a particular phenomenology, in a way that might be comparable to being in a ‘flow state’. Due to the trouble such psychological accounts of (...) fun have in explaining both the precise conditions of fun and also why some activities are thought to be enjoyable but not fun, a deflationary theory is instead introduced. This proposed alternative account suggests that the use of the word ‘fun’, when describing activities in English sentences, signals that the sentence is a generic sentence, an idea based on a semantic distinction made by Greg Carlson (1989). Further, it is argued that the words ‘pleasurable’ and ‘enjoyable’ are reserved for non-generic sentences, leaving the use of the word ‘fun’ to signal something akin to a grammar relation, rather than referring to a feeling or psychological state.

This book helps understand Plato’s writings by describing the circumstances in which they were produced. The author begins with an account of Plato’s life and development and a brief analysis of some of the more difficult points arising from the criticism of Plato’s writings. The remainder of the work considers the total setting – political, literary and philosophical – in which Plato’s writings were produced. There are extensive appendices on the Platonic Epistles, Aristotle and the Theory of Ideas, and on (...) the post-Aristotelian tradition. The result is both a lucid account of Plato himself and a comprehensive view of culture in fifth century Greece. (shrink)

How long does a quantum particle take to traverse a classically forbidden energy barrier? In other words, what is the correct expression for quantum tunnelling time? This seemingly simple question has inspired widespread debate in the physics literature. I argue that we should not expect the orthodox interpretation of quantum mechanics to provide a unique correct expression for quantum tunnelling time, because to do so it would have to provide a unique correct answer to a question whose assumptions are in (...) tension with its core interpretational commitments. I explain how this conclusion connects to time’s special status in quantum mechanics, the meaningfulness of classically inspired concepts in different interpretations of quantum mechanics, the prospect of constructing experimental tests to distinguish between different interpretations, and the status of weak measurement in resolving questions about the histories of subensembles.

Whatthe influences were which led to the development and formulation of the so-called Theory of Ideas, usually associated with the name of Plato, is a question of perennial interest. And the interest has been increased by the vigorous controversy that, during the last ten years, has been conducted round the question of the exact part played by Socrates in the development of this theory. All the available evidence on the question is accessible and familiar to students of Greek thought, and (...) has been worked over many times. But as there is still no unanimity among scholars as to its true interpretation, it may be worth while to go over the ground once more, even if the only result is to confirm some view which has already been put forward and disputed.

Originally published in 1921, updated in 1932 and re-issued in 1966 with an introduction by Stephan Körner, this book remains a classic introduction to the study of ethics. It clearly explains both the Aristotelian and the Kantian approach to ethical problems, by combining the advantages of a historical and systematic introduction. Much of the book is devoted to Aristotle and Kant, whose moral theories are important and who are influential forces in contemporary moral philosophy.

In a previous article, I have attempted to summarize the evidence of Aristotle about the relations of Socrates and Plato in the development of the theory of Ideas. It may be of interest now to carry the enquiry further, and to see whether writers later than Aristotle have anything of importance to say about the whole question of the general intellectual relationship between the two men. In particular we must enquire whether or how far they regard or say anything to (...) lead us to regard the Dialogues of Plato as a record of Plato's own thought or as a biographical account of the thought of Socrates or—a third possibility—as both at the same time. And, in addition to this, we shall have to attempt some estimate of the value, if any, which we can put upon such statements—an estimate which would depend in its turn on our answer to the question how far they had access to original sources of information no longer extant.

The Platonic Commentators.—After Cicero the Academy is no more than a few names to us for nearly five centuries. The nearest that we get to contact with it in this period is in the writings of Plutarch. He was himself a student there, and was well read in the books of Plato and the commentaries thereon.

Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
