Abstract
Although tolerance is widely regarded as a virtue of both individuals and groups that modern democratic and multiculturalist societies cannot do without, there is still much disagreement among political thinkers as to what tolerance demands, or what can be done to create and sustain a culture of tolerance. The philosophical literature on toleration contains three main strands. (1) An agreement that a tolerant society is more than a modus vivendi; (2) discussion of the proper object(s) of toleration; (3) debate about whether there is a ‘paradox’ of toleration and, if so, how it might be solved. This Introduction outlines how each of the subsequent papers addresses problems in the theory and practice of toleration, in the light of these three strands in the existing literature.
