Dr David Fallon has published an essay entitled 'Philoprogenetive Blake' in 
Blake, Gender and Culture (Pickering & Chatto, 2012). David contextualises Blake’s apocalyptic representations of sexuality, 
especially female sexuality, within eighteenth- and nineteenth-century 
discussions of British population. Until the first British census in 
1801 and Thomas Malthus's
Essay on the Principle of Population (1798), radicals, led by Richard Price, were ‘philoprogenitive’, promoting population growth as a
 sign of a lively body politic. They believed that Britain’s population 
was in decline, reflecting the failures of its
 despotic government to deliver the peace and plenty necessary to a 
burgeoning population. The essay traces Blake’s links to the 
Enlightenment population debate and its contributors, especially his 
hostility to Malthusianism, and notes the importance of philoprogenitive
 discourse to a number of his poems, including 
Visions of the Daughters of Albion,
America, and 
The Four Zoas.  
Blake’s repeated modifications of this discourse emphasise qualitative 
female sexual pleasure, which complicates both the traditionally 
quantitative language of philoprogenitivism but also recent feminist 
assessments of Blake as a misogynist.
