Why is the history of ideas dominated by male thinkers? Is it because women are discouraged from intellectual life - or is it because women tend to choose other careers?

If we go even deeper: why do women (and men) make the choices they do? Is it because they are influenced by overwhelming societal pressures - or are they acting freely?

These are the questions I've asked Dr. Michelle Boulous-Walker, who teaches at the University of Queensland in Brisbane, Australia.
