The Law was originally published in French in 1850 by Frederic Bastiat. It was written two years after the third French Revolution of 1848 and a few months before his death of tuberculosis at age 49. It is the work for which Bastiat is most famous. This translation to American English is from 1874.
"Many philosophers have made important contributions to the discourse of liberty, Bastiat among them. But Bastiat's greatest contribution is that he took the discourse out of the ivory tower and made ideas on liberty so clear that even the unlettered can understand them and statists cannot obfuscate them. Clarity is crucial to persuading our fellowman of the moral superiority of personal liberty."
- Walter E. Williams, from the Foreword
