Horowitz was born in Jerusalem in 1936 and immigrated to Canada citation needed] at the age of 2. His father Rabbi Aaron Horowitz, was a prominent member of the Jewish community and a key figure in founding Camp Massad in Canada. He grew up in Calgary, Winnipeg, and Montreal.[
Horowitz earned his Bachelor of Arts degree from United College. He earned his Master of Arts degree from McGill University in 1959, writing his thesis on Mosca and Mills: Ruling Class and Power Elite. He earned his Doctor of Philosophy degree 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 specialized 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 the Second World War, 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. A 21-part video series called 'Radical General Semantics' has been made of his lectures.
