How well the book succeeds in convincing the reader that a common good ought to act as a basis for evaluating the role of political establishments may be unclear. But there can be little doubt that the work is one of the most important contributions to political philosophy made by any English philosopher, and almost certainly the single most important contribution made by any British idealist. The book has attracted philosophers, sociologists, politologists and others since the day of its appearance, and continues to fuel lively debate today.
