Faculty members at Harvard University are set to vote tomorrow on whether to declare a lack of confidence in the leadership of president Lawrence Summers, or whether to forgive him.

The Faculty of the Arts and Sciences, one of 10 faculties at Harvard, is expected to vote on two competing resolutions. One, put forward by anthropology professor J. Lorand Matory, states: “The Faculty lacks confidence in the leadership of Lawrence H. Summers.”

The alternate resolution by a professor of government and sociology, Theda Skocpol, both reproves and pardons the president, who triggered a firestorm of criticism about his leadership when he suggested at a conference in January that there may be “intrinsic” differences in aptitude between men and women.

The second resolution expresses “regret” about the president’s leadership style and about comments he made in an off-the-record speech before the National Bureau of Economic Research on January 14.

That resolution, which is likely to prevail, also states that the faculty “appreciates the President’s stated intent to address these issues, and seeks to meet the challenges facing Harvard in ways that are collegial and consistent with long-standing faculty responsibilities in institutional governance.”

In a faculty meeting last month, Mr. Summers pledged “to listen more, and more carefully, and to temper my words and actions in ways that convey respect and help us work together more harmoniously.”

The resolutions are symbolic and not binding, since Mr. Summers serves as president at the pleasure of the Harvard Corporation.
