Henry Charles Carey

 He began work on a text, The Harmony of Nature, which he did not feel adequate for wider publication but which became central to his later thinking.^[5] Setting this work aside, he began Principles of Political Economy in 1837, an expansion of his refutation of Senior.^[8] He completed the three-volume work in 1840. This work was largely adapted by the French economist Frédéric Bastiat in his own Harmonie Economiques in 1849, with some later accusing Bastiat of plagiarism.
