Sir, - The metaphysical sparring of Drs O'Donnell (November 24th) and Reville suggests the onset of another acute attack of Bell's Theorem or some similar affliction. The good doctors should be wary of committing themselves at this time lest, at some point in the future, their past catches up with them. - Yours, etc., Eamonn Sweeney,
South Hill, Dartry, Dublin 6.
