David Playfair Heatley, Diplomacy and the Study of International Relations (1919)
“ How can we institute and establish a Society in which liberty, under external laws, is combined in the greatest possible measure with irresistible power? It is the most difficult of problems: its perfect solution is not to be looked for, so crooked is the wood out of which men are carved. It will be the latest to find a practical solution, for the pre-requisites are of an exacting character—correct appreciation of the nature of a possible constitution; vast experience drawn from the practice of the ages, and especially a good will favourably disposed towards the reception of the solution. ”
