George Bernard Shaw

[D]o not be oppressed by the frightful sum of human suffering; there is no sum; two lean women are not twice as lean as one, and two fat women are not twice as fat as one. Poverty and pain are not cumulative; you must not let your spirit be crushed by the fancy that it is.

George Bernard Shaw, The Intelligent Woman’s Guide to Socialism and Capitalism, London, 1828, sect. 84
