Contemporary liberal political justification is often accused of preaching to the converted: liberal principles are acceptable only to people already committed to liberal values. Catriona McKinnon addresses this important criticism by arguing that self-respect and its social conditions should be placed at the heart of the liberal approach to justification. A commitment to self-respect delivers a commitment to the liberal values of toleration and public reason, but self-respect itself is not an exclusively liberal value.

A key reason for pessimism with respect to greenhouse gas emissions reduction relates to the ?motivation problem?, whereby those who could make the biggest difference prima facie have the least incentive to act because they are most able to adapt: how can we motivate such people (and thereby everyone else) to accept, indeed to initiate, the changes to their lifestyles that are required for effective emissions reductions? This paper offers an account inspired by Rawls of the good of membership of ?intergenerational cooperative union? to achieve justice that provides a solution to the motivation problem

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.
