 Most of the works for which Shaftesbury is famous were written between 1705–1710. It was during this period that he rewrote the Inquiry concerning Virtue, or Merit and completed versions of The Moralists: A Philosophical Rhapsody (the first version of which was called The Social Enthusiast, A Philosophical Adventure), A Letter concerning Enthusiasm, Sensus Communis: An Essay on the Freedom of Wit and Humour, and Soliloquy, or Advice to an Author.
