"Nothing more strangely indicates an enormous and silent evil of modern society than the extraordinary use which is made nowadays of the word 'orthodox'. In former days, the heretic was proud of not being a heretic. It was the kingdoms of the world and the police and the judges who were heretics. He was orthodox." So begins "Heretics" by Gilbert K. Chesterton and his examination of the changing meanings of terms such as "orthodox" and "heretic" in the modern age. "Heretics" was originally published in 1905 and is a collection of 20 essays by the English poet, writer, philosopher, journalist, and lay theologian. Chesterton has been called the "prince of paradox" and is well known for his ability to turn popular sayings and allegories inside out in order to make a point. In "Heretics" he turns his considerable literary skills to a criticism of the rise of ambiguity and vagueness when ideological substance and certainty is superior. He also calls upon popular and public figures to stop being silent and to provide moral and philosophical direction that is so badly needed. "Heretics" is a thoughtful and classic piece of religious exposition. This edition includes a biographical afterword.
