The beginning of "Orthodoxy" sets the stage for Chesterton's journey of self-discovery as he contemplates his philosophical position. He recounts the influence of prior critics and emphasizes the importance of providing an explanation for his faith. He uses a vivid metaphor of a man discovering England, implying that his philosophical journey mirrors a realization of pre-existing truths. Chesterton argues against the modern tendency to deny fundamental human experiences, such as the existence of sin, while asserting the need for a romantic view of the world that combines wonder with a sense of belonging. This opening section establishes a personal narrative intertwined with broader philosophical discussions, ultimately serving as an invitation to readers to reflect on their beliefs.
