Part 64 - Copy letter from Henry Sidgwick to Victoria Welby

Thanks Welby for sending him her two pamphlets [Ambiguities and Apparent Paradox], which he discusses. Declares that it is a difficult matter 'to persuade a plain man to go through the process necessary to attain precision of thought: it requires great literary skill in presenting the process.' Claims that he tried to do something of this sort in his Principles of Political Economy, but fears that he bored the readers. States that he would like to see Herbert Spencer's answer to Apparent Paradox. States that if she wants to call Locke as a witness 'it would be easy to find suitable quotations in Chap. IX of Book III of the Essay on Human Understanding, and that with regard to Bacon, there is Aphorism XV in the Novum Organum. Believes that modern instances are more impressive however.
