C. D. Broad wrote that Keyne’s Formal Logic ’was the text-book in formal logic for many generations of Cambridge moral scientists. It is far and away the best book that exists in English so the old-fashioned formal logic and the earlier stages of the more recent developments’ (‘The local historical background of contemporary Cambridge philosophy’, in C. A. Mace, British Philosophy in the Mid-Centurv, London: George Allen & Unwin, 1957, p. 21). Russell, on the other hand: 'When I was young [J. N. Keynes] taught old-fashioned logic at Cambridge.

I do not know how far the new developments in the subject altered his teaching. He was an earnest Nonconformist who put morality first and logic second'. Part IV of Formal Logic contains an ingenious account of ‘logical processes in their application to complex propositions' which can serve as an example of the ptolcmaic elaboration req uired to make orthodox logic work.

His book on political economy was influential as a standard text J. A. Schumpeter wrote: 'Its perusal may be recommended even at this distance of time [in 1954] because of its merits as well as its success’.
