8vo. 206 pp. One leaf loose, publisher's cloth. Slightly browned. Later issue. - Alan Turing's copy, acquired by him at Cambridge. The front free endpaper is signed "A. M. Turing", with the date, "March 1933", at the foot. In March 1933 he purchased Bertrand Russell's Introduction to Mathematical Philosophy, which introduced him to "think seriously about the problem of 'types' - and more generally faced Pilate's question: What is truth?" (Hodges, ibid.). It is probable that Turing attended lectures on differential equations given at Cambridge by German mathematician Richard Courant in 1933.Provenance: Alan Turing (1912-1954); Robin Gandy (1919-1995), Turing's friend and one of his executors; bequeathed to Wolfson College. A Fellow of Wolfson from 1970 until his death in 1995, Gandy generously left his entire estate to the College, including these books once owned by Alan Turing, with the wish that his legacy be used to benefit the College and its students.
