David Wippman, president of Hamilton College (NY) and Glenn C. Altschuler, professor of American studies at Cornell University (NY), write: Just a few weeks ago, colleges and universities across the country anticipated a relatively normal fall semester. Now, with the Delta variant surging, confidence has given way to apprehensiveness. At many institutions, mask mandates have returned, along with fears of an escalating series of “déjà vu all over again” restrictions. These fears are understandable, especially at campuses with low vaccination rates. But this year is different. We should be able to balance safety and normalcy much more effectively, to have our cake and eat it, too.
