Much has been said and written about the unique position regarding toleration that was adopted by Rabbi Abraham Isaac Kook. Its uniqueness within Jewish tradition is not open to doubt. The question I would like to explore here is the extent to which his version of toleration is compatible with the toleration that has become part of the modern secular outlook. In order to accomplish this task, I begin by setting up a typology of two basic varieties of toleration, relating one to the skepticism of the relativist who espouses liberal pluralism, and the other to religious systems with absolutist claims for truth. In the second part of the article, a sketch of the history of toleration in Judaism, this typology is confirmed. The third part of the article is a review of R. Kook′s notion of toleration, which seems at first to conform to the type of toleration generally associated with liberalism, but, when translated into practical policy, displays some significant aberrations. The fourth part suggests that these aberrations are not evidence of inconsistencies or anomalies, but rather an indication of the fact that no attitude of toleration, even that of the most liberal pluralist, can completely evade the necessity for intolerance at some point; and that different views regarding the point where toleration should be limited reflect different epistemological positions, each of which is associated with a different societal ideal which serves as the criterion for limiting toleration.
