Bertrand Russell's eminence of intellect and person has long been unassailable. Besides his distinction as mathematician and philosopher, and a vast output of books, articles, lectures and talks on most aspects of the human condition, there is his continuing concern for day-to-day political issues, his championing of individual freedom and his readiness to stand for a cause to the point of imprisonment. To have distilled the essence of his ninety-odd years into this little book is itself quite an achievement. Originally published in 1962, it has been called a 'pocket guide to greatness' and forms a useful complement to the longer and slightly earlier study by Alan Wood's The Passionate Sceptic.
