What is the theme in Proof by David Auburn?

Academic chauvinism is another theme. For many generations, women have been excluded from the ranks of academic achievement, particularly in the fields dominated by men, such as mathematics and science. Sophie Germain's story is vital to Catherine's world view, as Germain is the only historical role model available for her. Women have not traditionally received the support men do from these male dominated fields. Men have many role models to look to and are more likely to receive additional support from older, wiser professors or other experts in the field who desire to give back by helping their chosen protégés to develop their budding skills. Women have often faced a hostile and unwelcoming environment, which means not only do they lack support, but they also face more challenges and obstacles than do their male peers in the field.
