"Maggie" Osler (November 27, 1942 – September 15, 2010) was a historian and philosopher of early modern science and a professor of history at the University of Calgary.
Osler's work concentrated on the history and context of the Scientific Revolution and the relation of early modern science to religion.
Osler argues that Boyle drew on Gassendi's writings as he developed his Christianized corpuscular natural philosophy.
Osler traces two different epistemological traditions which converged on the mechanical philosophy and which produced two contradictory attitudes toward scientific knowledge.
"Osler shows that empiricist and rationalist "theories of knowledge were rooted in the theological traditions from which the systems emerged."
