I’ve just recently returned from holidaying in the United States on the coast of Maine. While there I happened to meet Professor Fred Kaplan, who is a distinguished author of literary biographies. His most recent, Lincoln, the Biography of a Writer, is a book that I found fascinating, not least for its insights on leadership. In Lincoln’s case – and many in the US believe him to have been the greatest ever President – there can be no doubt that his love of literature played a pivotal role in shaping and sustaining him as a leader. This seems to me a point worth pondering given that we now live in a culture that values the explicit and measurable over the implicit and inherently unmeasurable.
