Law of Population Law of Population (1830) was a massive treatise written by Michael Thomas Sadler as a response to Thomas Robert Malthus's works on population growth, notably "An Essay on the Principle of Population" (first edition 1798). In his essay, Sadler refutes Malthus' conclusions regarding the geometric growth of populations and proposes that the growth of populations is a far less worrisome menace. At this period population growth had become a "political bugbear" throughout England, much in a way comparable to modern day fears of terrorism or Cold War fears of nuclear war.
