At the present time we have come to take a calm view of the question so much debated seven years ago as to the legitimacy of logical arguments in political discussions. No longer, fortunately, can that intense feeling be roused which then found expression in the famous cry, "Justice--right or wrong," and which played such a large part in the politics of that time. Thus it will not be out of place in this unimpassioned record of some of the truths and errors in the world to refer briefly to Mr. R*ss*ll's short and stormy career. Before he was torn to pieces, he had been forbidden to lecture on philosophy or mathematics by some well-intentioned advocates of freedom in speech who thought that the cause of freedom might be endangered by allowing Mr. R*ss*ll to speak freely on points of logic, on the grounds, apparently, that logic is both harmful and unnecessary and might be applied to politics unless strong measures were taken for its suppression. On much the same grounds, his liberty was taken from him by those who remarked that, if necessary, they would die in defence of the sacred principle of liberty; and it was in prison that the greater part of the present work was written. Shortly after his liberation, which, like all actions of public bodies, was brought about by the combined honour and interests of those in authority, occurred his lamentable death to which we have referred above. Mr. R*ss*ll maintained that the chief use of "implication" in politics is to draw conclusions, which are thought to be true, and which are consequently false, from identical propositions, and we can see these views expressed in Chapters III and XIX of the present work. These chapters were apparently written before the Government, in the spring of 1910, arrived at the famous secret decision that only "certain implications" are permitted in discussion. Naturally the secret decision gave rise to much speculation among logicians as to which kinds of implication were barred, and Mr. R*ss*ll and Mr. Bertrand Russell had many arguments on the subject, which naturally could not be published at the time. However, after Mr. R*ss*ll's death, successive prosecutions which were made by the Government at last made it quite clear that the opinion held by Mr. R*ss*ll was the correct one. There had been numerous prosecutions of people who, from true but not identical premisses, had deduced true conclusions, so that the possible legitimate forms of "implication" were reduced. Further, the other doubtful cases were cleared up in course of time by the prosecution of (1) members of the Aristotelian Society for deducing true conclusions from false premisses; (2) members of the _Mind_ Association for deducing false conclusions from false premisses; and also by the attempted prosecution of an eminent lady for deducing true conclusions from identities. Fortunately this lady was able to defend herself successfully by pleading that one
