Macdonald is described as a man of phronesis who possessed a sophisticated political philosophy which, in general, conformed to the political disposition exemplified by Edmund Burke. Macdonald's views on the constitution, change, representation, democracy, women, tradition, economics, religion and unions are investigated. It is concluded that Macdonald was an anti-rationalist who saw the world in terms of loyalty, duty and obligation and who was devoted to the principles of prudence, tradition and the rule of law, to constitutional monarchy, to the British connection and British institutions but with respect for French traditions, to the minimal change consistent with harmony, to order before liberty, politics before economics and experience before abstract reason.
