CorrectionsSeptember 22nd, 2008. I have just spotted some bad typos (omitted negation symbols) in ch.2 of Reason and Reality p.32. If you have downloaded this chapter, please do so again from the corrected version.
October 2nd, 2008. I was dismayed to find yesterday that although I had entered many corrections to ch.2, my computer had managed to replace the corrected files with uncorrected ones. I think the current text is correct. But if you spot any errors, please E-mail me.
Old NewsSeptember 16th, 2006
I have put chapters of my book, Reason and Reality, on the web, as a series of pdf files. My reasons are partly prudential, partly ideological. Publishing hardback in the traditional manner is slow and tedious, and offers no opportunity of rectifying errors (and I make many typos, as well as more serious mistakes) until the print run is sold out. Plato said that books were a poor substitute for dialogue, and the internet allows for intellectual interchange in a way that was impossible with the old technology. And finally, hardback books are too expensive for most people to buy. I have always warmed to Hillaire Belloc's lines
When I am gone, let only this be said:
His sins were scarlet, but his books were read
I, too, would rather be read than be rich. You are welcome to download and print for your own use what I have put on the web, as outlined in my copyright notice below. It seems that enough people would want hardcopies to interest a publisher, namely Ria University Press. The hardback edition (ISBN 13: 978-1-934297-04-9) and the paperback edition (ISBN-10: 1934297046) have now been published in the USA at $44.44, and can be ordered through Amazon.com and bn.com and should be available from all Expresso Book Machines world wide. Blackwell's have an Expresso Book Machine in their Charing Cross Road branch, 100 Charing Cross Road, WC2H 0JG.
Corrigendum p.270, l.21 shuld read ``The dual parentage of space endows it with different ambitions.''
If you cannot get a printed copy, then it is still available on the web: to read particular chapters, use this link to take you to the table of contents; and then to view a particular chapter, click on the chapter number. Or go to section VI below. I recommend 100% or 125% magnification. I haven't yet learnt how to do an index in TEX or pdf. In some chapters my computer complains she cannot find the right font, and suggests using Helvetica instead. If I click OK, she seems to be happy to go on.
Less New News
Each week on Sunday morning I receive an E-mail telling me what hits I have had during the previous week; which may make me suffer from the sin of pride, or, more usually, from depression, before I go to our village church. Recently there has been a sudden jump in the hits for my ``Tables''---79 last week. When I looked at it myself, I found that it was not one I had written against the Norrington Tables for Oxford in 1980, but a subsequent follow up article in the Oxford Magazine. I think the earlier one was better, and have now included Norrington Blues
I have now managed to convert TEX files including diagrams into PDF ones that can be read by Adobe Acrobat. I am producing replacement chapters for those in my The Conceptual Roots of Mathematics containing typographical errors. For details see
Corrigenda to The Conceptual Roots of Mathematics,
On November 6th, 2003, I stood in for Bishop Wilberforce at the British Academy, at 5.15pm, saying what he might have said now, with the benefit of 143 years hindsight, to a neo-Huxley (represented by Professor Janet Browne).
I have put a summary of the case for Bishop Wilberforce on the web, together with a semi-transcript of Professor Browne's and my contributions
An Engagement with Plato's Republic, by Basil Mitchell and me, has been published by Ashgate.
It is not a standard commentary. Rather, it is a deliberately anachronistic attempt to make Plato accessible to the modern reader, and to engage him in dialogue with modern problems. Publisher's Blurb It was published on September 5th. It should have come out much earlier, but most unfortunately there was a muddle over the book-jacket, which was to be an adaptation of Raphael's School of Athens showing Plato talking with his pupils, some of them altered to be in modern dress and using a word-processor. Owing to a breakdown in communication an uncorrected proof was used, with Plato more or less eclipsed by `Basil Mitchell' and `J.R. Lucas'. This was not the message we wish to convey. A new book-jacket has been printed, both for the hard-back and for the paper-back editions. If you buy the paper-back, make sure you have the correct outside, with us deferentially down in the right hand corner, taking our place among Plato's pupils, not lording it over them. To encourage you to read further, I have made available on this site as pdf files: the contents, introduction, envoi and an analysis of the text , together with chapters 1, 3 and our most provocative chapter, 10, Sex, Self and Power
(They can be read by Adobe Acrobat---I recommend 150% magnification).The book can be ordered from Ashgate:

If you want to include an article of mine in an anthology, you should ask my permission, which will be granted on the following terms:

VII Ethical EconomicsCan a businessman be moral? What are the values implicit in a business deal? Is there such a thing as economic justice?
Ethical Economics, by M.R. Griffiths and J.R. Lucas was published on January 8th, 1997, by Macmillans.
It examines the fundamental principles of economic activity in order to enable people to answer these questions, and think through the problems they face, and to reach their own decisions. It argues that business relations are sustainable only against a background of the parties having some values in common, and in consequence there is a point of entry for ethical considerations in economics: but there are significant divergences of interest between the parties to a business transaction, and therefore the morality of business life is less personal and more external than it is in families and close-knit communities.
It was reviewed by Samuel Brittain in The Financial Times, June 5th, 1997.
By February, 2007, it was almost unavailable, though Amazon can sell copies at $95 plus $9.95 packing and posting. By the end of 2008 it had earned a place in my ``I Told You So'' column. I hope to have made most of it available by clicking on on the link: Ethical Economics,

VIII The Conceptual Foundations of Mathematics, Revised
The Conceptual Roots of Mathematics was published by Routledge on Friday, October 15th, 1999.
It is dedicated to
all my colleagues
I have had many colleagues, and have been greatly helped by them, some of them unknown to me. I dedicated an earlier work, Space, Time and Causality to Eric James and all my teachers, and wrote to those I could and told them so. I dedicated Responsibility to all my pupils, and put their names on the book-jacket. I have listed in colour the names of those in Merton with whom I have shared pupils, those I have given lectures and seminars with, and those with whom I have worked on other projects in Oxford, Cambridge, Leeds, Edinburgh, the British Society for the Philosophy of Science, and elsewhere. But there are many others whose names could well appear here, to whom also the book is dedicated with grateful thanks.
Corrigenda to The Conceptual Roots of Mathematics, There were an embarrassing number of typos in the published edition. These are listed in Corrigenda to The Conceptual Roots of Mathematics, together with pdf files of the corrected chapters. But I have been worrying away at some of the loose ends I had not tied up properly, and have now written three chapters that are markedly different from the published version.
I need to give a better account of infinity, and re-do the final chapters, but I have other pressing concerns, so publish these three chapters on their own.
I am grateful to someone from Greece who telephoned me on the morning of January 20th, 2005, to tell me of another misprint in The Conceptual Roots of Mathematics. He gave me his E-mail address, but it bounced, as his to me had earlier. Will he please accept this as my thanks for his correction, and my apology for not having got back to him within half an hour, as I said I would. If he writes to me by snail-mail, I shall gratefully and apologetically respond.
I had an E-mail from a schoolgirl in Australia, asking for details about myself. An abridged version of her letter and my response gives some information about me. More recently I had another one from California, which I give in me2.
More recently still, my son found an entry in an on-line encyclopaedia: me3
Two further ones are: an interview in Estonian, published in Postimees on 28th of April, 2012 aa,\A>
an article in Dutch on a website on theology called Lucepedia.
I give in an account of how I stumbled on the real meaning of Barabbas..
