Partie 3 - Copy of a letter from Henry Sidgwick to Lady Welby-Gregory

Typewritten copy of letter dated 22 September 1893. Asks her to arrange for a search to be made of the room he occupied for some letters and postcards that he left behind there. Discusses Welby-Gregory's 'idea of "Significs" ', and asks what there is to be known about the relations of things beyond what is known of them already, what is the value or worth of things, and what is 'the ultimate End or Good to which all the processes of change in the world'. Says the last question is 'the fundamental question of philosophy', and discusses the likely reaction of the scientist and the logician to it.
