The literature on collapse includes Joseph A. Tainter (1988), The Collapse of Complex Societies, Jared Diamond (2005), Collapse; Richard Heinberg (2003), The Party’s Over; and Ronald Wright (2004), A Short History of Progress. For the very long-term view, see Peter Ward and Donald Brownlee (2002), The Life and Death of Planet Earth. The difficulties—“the multi-front predicament”—of achieving a managed downsizing of a complex connected system which depends on all its mutually dependent parts being in full working order are discussed by David Korovicz (2010), Tipping Point. For “one deep calleth another”, cf. Psalm 42:7.
