First, Andrew says he does not see why we need a universal account of how we can sustain our institutions.
Margaret Thatcher set out her vision of a rich civil society in her speech to the Church of Scotland. Hers was an explicitly religious appeal. The challenge I set myself was to achieve the same purpose without recourse to religious obligation. This is not to say that the religious approach is wrong, but I think there is value in meeting John Rawls' idea of "public reason". This is to say that we should try wherever possible to explain our policy in terms which all members of our society can agree on and do not rely on any personal sources of reason, such as religious conviction.
