Five of the ten largest classes at Harvard have enrolled about twice as many men as women, according to figures compiled by the Office of the Registrar.

Mathetics 21b, Literature and Arts C-61, "Rome of Augustus," and Philosophy 192, "Thinking about Thinking" all have male-female ratios over the 66-33 percent line.

Social Analysis 10, Moral Reasoning 40, "Confucian Humanism," have ratios of 63 to 37 and 59 to 41, respectively. The overall Harvard College ratio is 43 percent women to 57 percent men, according to the 1994 edition of Peterson's Guide to Colleges.

Professors and teaching fellows offer a variety of explanations for the gender disparities in their classes.

Literature and Arts C-61, "The Rome of Augustus," has an enrollment of 204 men and 93 women, according to the Registrar's numbers.

The gender disparity in the course is less this year than previously, Pope Professor of the Latin Language and Literature R. J. Tarrant Said.

Tarrant said the gender gap might be due to the course material.

David H. Goldbrenner '96, a student in theclass, agreed that the course's focus is connectedto its gender ratio.

"I guess if I were in the Women's StudiesDepartment, I'd say that guys are attracted to thepatriarchal glory of Ancient Rome," he said.

Taa R. Grays '94, a female student in theclass, did not feel there was any reason why womenshould avoid the class.

"I don't think there is any bias in the classand I don't know why women wouldn't want to takeit," she said.

The explanation for the enrollment disparity in"Thinking about Thinking" is not the coursematerial--which encompasses nearly all of humancognition--but the sex of the professors, one ofthem said.

"I'm surprised at the disparity and I wonder ifit's due to the luck of the lottery or to the factthat three male professors are teaching it," saidFrankfurter Professor of Law Alan M. Dershowitz,one of the three male professors who teach theclass.
