Wolfson was a tireless scholar. About him writes, "He was reminiscent of an old-fashioned
gaon, transposed into a modern university setting, studying day and night, resisting presumptive attractions and distractions, honors and chores, with a tenacity which sometimes seemed awkward and antisocial." He spent vast amounts of time secluded in the
Widener Library pursuing his research. writes that even in his retirement, Wolfson was "still the first person to enter Widener library in the morning and the last to leave it at night." Wolfson wrote works including a translation and commentary on
Hasdai Crescas'
Or Adonai, the philosophy of the church fathers, the repercussions of the
Kalam on
Judaism, and works on
Spinoza,
Philo, and
Averroes. The best-known of these works are listed below, their publication in several instances—among them the work on Philo—having been considered scholarly events of the first magnitude. Wolfson was additionally known as a "daring" scholar, one who was not afraid to put forward a bold hypothesis with limited evidential support. In his work Wolfson therefore often chooses bold conjecture over safe, but boring, analyses .

Philo: Foundations of Religious Philosophy in Judaism, Christianity and Islam, Harvard University Press (1947). Until the publication of this book, Philo had been considered no more than a preacher with a philosophic bent. Wolfson showed that behind the philosophic utterances scattered throughout Philo's writings there lay a coherent philosophic system. Wolfson went even further, claiming that Philo was the founder of religious philosophy in Judaism, Christianity, and Islam, and that "Philonic" philosophy dominated European thought for 17 centuries until it was destroyed by Spinoza,
the last of the medievals and the first of the moderns. •
