When I had to write a major speech outlining Prime Minister Malcolm Fraser’s political philosophy—not the easiest of tasks, given that Fraser, though gifted with a strong intelligence, was not comfortable expressing himself in terms of abstract ideas and principles—I did so with Irving’s Two Cheers for Capitalism open at my elbow. The speech was later published as a definitive statement of Fraser’s beliefs, and I wish I had a copy on hand to find out how much I had plagiarised.
