Peter Hennessy is a historian and a dreamer ... Here is the vision of a kinder Britain, shared by the creators of the welfare state in the first postwar years ... Hennessy's book is a recital of reflections upon a long and often brilliant career as a social and political observer ... He sees huge challenges ahead in social care, social housing, climate change, artificial intelligence, technical education and the fragility of the Union, which present policies are quite inadequate to address. ... At the heart of the author's thesis is his contention that the British people during the pandemic have shown themselves to be much better than their rulers; that we must find means to mobilise our true national spirit through a nobler politics ... His enthusiasm and, yes, virtue shine through its pages, together with his rage towards those who fail us in the "duty of care" of his title. It is an inspirational work.
