"What would have happened if Michael Collins had lived? This again is a question asked incessantly in Ireland and though I have already dealt exhaustively with questions of speculation, and hesitate to weary the reader with issues which, by definition, must be totally matters of opinion, some evaluation is called for. Obviously he had a greater grasp of economics than his contemporaries and would have brought more drive, efficiency and imagination to bear upon the task of building up the country after the civil war than did anyone in any government or party that came after him. My opinion, and it has to be based purely on speculation, is that Ireland would have benefited enormously had he lived. Unlike de Valera whose talent lay in getting and holding power, Collins asked himself the question, 'All this for what?', and tried to provide the answers. However practical or impractical his recorded thoughts may have been they were the thoughts of a still-young man, capable of great development; a man who, in the eye of the storm, was able to take time to try to plot a course for his people and his country."
