If you think about the 18th century, say, if you think about intellectual life before the late 19th century, anything you did, anything you thought about, whether it was the physical world, the human world, the natural world apart from the human world, or morality, anything you did would have been framed against the background of a set of assumptions that were religious, Christian assumptions.
你设想一下十八世纪， 如果你设想一下 十九世纪以前的知识界， 所有你做的事，你想的事， 无论它是属于物理界， 人类社会， 除了人类社会以外的自然界， 或者是伦理道德方面，所有你做的事 都会被当时的社会背景中的条条框框所限制住， 也就是宗教的背景， 基督教的背景。
