Many years ago, SHI Founder Rabbi Prof. David Hartman wrote a lengthy essay about Purim which he distributed to small groups of friends of the Institute. Senior Fellow Noam Zion saved a copy of the essay, which has been scanned for digital use.
From the opening paragraph:
The story of Purim is a classic account of our people’s confrontation with brute anti-Semitism. Our bodies and not only our spirit were threatened with extinction. Nevertheless, Haman’s genocidal scheme was not realized.
