Title: Isabel Paterson
Passage: Isabel Paterson (January 22, 1886 – January 10, 1961) was a Canadian-American journalist, novelist, political philosopher, and a leading literary and cultural critic of her day.  Along with Rose Wilder Lane and Ayn Rand, who both acknowledged an intellectual debt to Paterson, she is one of the three founding mothers of American libertarianism.  Paterson's best-known work, her 1943 book "The God of the Machine", a treatise on political philosophy, economics, and history, reached conclusions and espoused beliefs that many libertarians credit as a foundation of their philosophy.  Her biographer Stephen D. Cox (2004) believes Paterson was the "earliest progenitor of libertarianism as we know it today."  In a letter of 1943, Ayn Rand wrote that ""The God of the Machine" is a document that could literally save the world ... "The God of the Machine" does for capitalism what "Das Kapital" does for the Reds and what the Bible did for Christianity."
