Is liberalism adaptable enough to the ecological agenda to deal satisfactorily with the challenges of anthropogenic climate change while leaving its normative foundations intact? Compatibilists answer yes; incompatibilists say no. Comparing such answers, this article argues that it is not discrete liberal principles which impede adapatability, so much as the constructivist model (exemplified in Rawls) of what counts as a valid normative principle. Constructivism has both normative and ontological variants, each with a realist counterpart. I argue that normative constructivism in the Rawlsian mode, whatever its strengths elsewhere, is markedly ill‐equipped to deal with the particular normative challenges posed by climate change – and that that these doubts holds regardless of which stance is adopted as its ontological corollary.

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.
