|Known for||Red Tory theory|
Horowitz earned his BA from the University of Manitoba. He earned his MA from McGill University in 1959, writing his thesis on "Mosca and Mills: Ruling Class and Power Elite". He earned his Ph.D. from Harvard University in 1965, writing his thesis on "Canadian Labor in Politics: The trade unions and the CCF-NDP, 1937-62", with Sam Beer as his advisor.
Horowitz has specialised in labour theory, and most notably coined the appellation "Red Tory" in his application of Louis Hartz's "fragment theory" to Canadian political culture and ideological development, in his essay "Conservatism, Liberalism and Socialism in Canada: An Interpretation" (in the Canadian Journal of Political Science, 32, 2 (1966): 143–71). The use of this appellation differentiates traditional Canadian Toryism from the powerful classical liberal elements that began to emerge in the Conservative Party after World War II, but it has applications to conservative parties in other countries where "Tory" acceptance of state enterprises, the welfare state, and other institutions seen as expressions of national character conflicts with "liberal" or "neoliberal" rejection of state intervention in the economy.
Horowitz teaches a class at the University of Toronto entitled "The Spirit of Democratic Citizenship" which revolves around general semantics, a non-Aristotelian educational discipline first theorized by Polish engineer Alfred Korzybski.
