I read this book purely because it was on the topic of Compromise, which was of interest to me. And the book does contain some thoughtful reflections on problems with being too quick to compromise in a liberal democracy.
However, the style is dated, with long, convoluted sentences and sage 19th century pronouncements on the importance of truth, rationality, enlightenment, progress, and the like.
One wonders what Morley would make of today's 'post-truth' times, and a multipolar world with deep, polarising divides. I suspect he might be horrified, but also perhaps persist in urging people to redouble their efforts to encourage vigorous liberal debate. Don't be too quick to compromise, don't be too quick to attack, but remain unwavering in your commitment to keep reasoning and trying to settle on some form of enlightened truth. What else is there?
