He was led on from literary criticism to a more general critique of the spirit of his age. Between 1867 and 1869 he wrote "Culture and Anarchy", famous for the term he popularised for the middle class of the English Victorian era population: "Philistines", a word which derives its modern cultural meaning (in English – the German-language usage was well established) from him. "Culture and Anarchy" is also famous for its popularisation of the phrase "sweetness and light," first coined by Jonathan Swift.
