"Among Sir Ernest Barker's many interests and achievements...one was prolonged for some years after his retirement from most other activities, for he continued to work for better international understanding as a member of the United Kingdom National Commission for Unesco and as the first chairman of its National Co-operating Body for Philosophy and Humanistic Studies. To both he brought a wealth of wisdom and experience and the stimulus of all those qualities of vitality, candour and stern intolerance of nonsense so well brought out in your memoir, all of which made him so truly worthy and justly eminent a citizen of that Republic of Letters to which his life's work was devoted."
