The continuing churn of political advisers in Donald Trump's White House serve as a reminder of the salience and relevance of political advice. Political Advice: Past, Present and Future brings several very different voices to bear on the problem of advice and influence; the distinction in so far as it is valid between political and policy advice; the two-way parasitism of adviser and advised; the nature and idioms of political advice literature; the changing (and sometimes unchanging) nature of expertise; the ever-pressing issue of access and exclusion; and how that is controlled. This volume of essays feeds into a contemporary concern, set in a wider historical context. Moreover, the volume treats political advice in an interdisciplinary fashion with contributions from classics and literature as well as from history and politics. The unique practitioners' perspective to the problem of political advice is brought by the contributions of politicians, political advisers and senior civil servants. Appreciated and despised in equal measure, political advisers have been at the heart of government decision-making for many centuries. This valuable collection of essays digs deep into the history and more recent practice of political advice to expose why these advisers, while sometimes controversial, have been so valued by generation after generation of our political leaders.
