"Heretics" is a book about religion and politics, theory and fact, morals and efficiency. The best thing about "Heretics," written a bit over a century ago, is that his arguments are exceptional, and that so many of them are still quite recognizably true. He argues that the weakening and devaluing of religion has also weakened and devalued heresy. He argues that people should be able to speak freely -- but that freedom of speech has actually decreased people's willingness to speak about important issues, and so much more. In some ways, he was ahead of his time. You may disagree with him, but you can't deny his intelligence and wisdom. This isn't the book you might expect it to be. I think you'll enjoy it, and maybe even learn something, even if you disagree with it.
