George Ensor J.P. was an eminent Irish lawyer, radical political pamphleteer and freethinker. Among other conservative precepts, he pilloried the Malthusian doctrine that poverty is sustained by the "disposition to breed". As a hindrance to enterprise and prosperity, he pointed rather to the tyranny of concentrated wealth. In Ireland, it was a condition he believed could be reversed only through popular representation in a restored parliament. Ensor further outraged prevailing opinion by inveighing against the constitutional ascendancy not merely of Protestantism, but more broadly of the Christian religion. He argued that questions of morality and social justice cannot be addressed within a theology of salvation through faith.

Freethought is an epistemological viewpoint which holds that beliefs should not be formed on the basis of authority, tradition, revelation, or dogma, and should instead be reached by other methods such as logic, reason, and empirical observation.
