Thurlby Hall, Newark - EB returns George Green's memoir - 'altered and freely cut down, as yourself and Mr Murphy were so obliging as to suggest'. EB considers WW 'our sole calm examiner' on Political Economy, but 'was disheartened by 'Definitions come last', yet this is merely to say, that analysis precedes synthesis'. Under the title of 'Heresies' EB gives two kinds of Rent - 1. Of consumption and 2. Rent from capital invested: 'The equation has two roots, like the two spheroids of equilibrium, one the active speculating Rent of high let land, and the other the passive slovenly Rent of land underlet - the conditions of the Labouring Class depends on the number of farms sufficiently large to employ labourers. Parishes split into pieces are always at war with the poor, as each man is sufficient to labour his own land, and does not employ a labourer without compulsion'. EB claims that the word capital should be replaced with 'Productive Power, land, labour, machinery, money etc, all having distinct 'Laws' - It is incorrect to think labour alone productive'.
Thurlby Hall, Newark - George Green is very grateful to WW for all the 'presswork' he carried out for GG's maiden memoir. Another memoir is ready - could WW say whether it would be favourably received? EB Thanks WW for his pamphlet which he read twice 'and consider the most decisive thing of the kind, that I ever met with - We want the whole of Logic thoroughly sifted in the same manner'. EB commends WW's warnings about premature definitions - the best illustration is found in Botany where Linnaeus refused to define his natural families prematurely. Even in mathematics definition follows knowledge.
George Green and EB are grateful to WW for all his help with the printing and distribution of GG's memoir. Sends WW another memoir to WW by GG: 'the Cambridge Transactions ought to lead all others in mathematics. I am convinced that the want of them is deemed an affectation - You are right about practical analysis - the age of the Warings, the Quixotic Chivalry of science is gone for ever'. George Peacock's algebra - '(to use a comparison) he still begins the Differential Calculus from Velocities'. Richard Jones 'is certainly a very able man - his idea of the labouring Classes gradually coming under the domain of Capitalists, is striking and true'. The 'moral machinery' of industrialisation 'has not kept pace with the population'. WW's Bridgewater Treatise 'is very striking - It certainly places the whole affair on a new and solid foundation'. For EB 'the Belief of a Deity from a view of nature is a matter of impression - what brings direct conviction to my own mind would appear absurd to another, and I never could announce it without hesitating'.
Thurlby Hall, near Lincoln - Thanks WW for his attention to George Green's memoir. GG is keen to meet WW's 'views in every particular', and if thought necessary to come to Cambridge: 'Would it be too great a favour to request that you would become gardner in this pruning'. EB read the 'little book' WW sent him: 'The book is exactly what I have long wished to see - It set me musing, and I was struck with the parallel state of the progress of scientific Political Economy. There is room for Galileos. The key to progress seems by comparison to consist in giving technical names to complex ideas capable of mathematical definition'.
