Name: The Spirit of the Laws
Author: Montesquieu

Montesquieu Original title De l'esprit des loix (French, 1748)

The Spirit of the Laws is a treatise on political theory, as well as a pioneering work in comparative law, published in 1748 by Charles de Secondat, Baron de Montesquieu. Originally published anonymously, partly because Montesquieu's works were subject to censorship, its influence outside France was aided by its rapid translation into other languages. In 1750 Thomas Nugent published the first English translation. In 1751 the Roman Catholic Church added De l'esprit des lois to its Index Librorum Prohibitorum . Yet Montesquieu's treatise had an enormous influence on the work of many others, most notably: Catherine the Great, who produced Nakaz ; the Founding Fathers of the United States Constitution; and Alexis de Tocqueville, who applied Montesquieu's methods to a study of American society, in Democracy in America. Macaulay offers us a hint of Montesquieu's continuing importance when he writes in his 1827 essay entitled "Machiavelli" that "Montesquieu enjoys, perhaps, a wider celebrity than any political writer of modern Europe."

“Democratic and aristocratic states are not in their own nature free. Political liberty is to be found only in moderate governments; and even in these it is not always found. It is there only when there is no abuse of power. But constant experience shows us that every man who has power is inclined to abuse it; he goes until he finds limits. Is it not strange, though true, to say that virtue itself has need of limits?.
To prevent this abuse, it is necessary that, by the arrangement of things, power shall stop power. A government may be so constituted, as no man shall be compelled to do things to which the law does not oblige him, nor forced to abstain from things which the law permits.”

Book XI, Chapter 4.
The Spirit of the Laws (1748)

“In every government there are three sorts of power: the legislative; the executive in respect to things dependent on the law of nations; and the executive in regard to matters that depend on the civil law.
By virtue of the first, the prince or magistrate enacts temporary or perpetual laws, and amends or abrogates those that have been already enacted. By the second, he makes peace or war, sends or receives embassies, establishes the public security, and provides against invasions. By the third, he punishes criminals, or determines the disputes that arise between individuals. The latter we shall call the judiciary power, and the other, simply, the executive power of the state.
When the legislative and executive powers are united in the same person, or in the same body of magistrates, there can be no liberty; because apprehensions may arise, lest the same monarch or senate should enact tyrannical laws, to execute them in a tyrannical manner.
Again, there is no liberty if the judiciary power be not separated from the legislative and executive. Were it joined with the legislative, the life and liberty of the subject would be exposed to arbitrary control; for the judge would be then the legislator. Were it joined to the executive power, the judge might behave with violence and oppression.
There would be an end of every thing, were the same man, or the same body, whether of the nobles or of the people, to exercise those three powers, that of enacting laws, that of executing the public resolutions, and of trying the causes of individuals.
The executive power ought to be in the hands of a monarch, because this branch of government, having need of dispatch, is better administered by one than by many: on the other hand, whatever depends on the legislative power, is oftentimes better regulated by many than by a single person.
But, if there were no monarch, and the executive power should be committed to a certain number of persons, selected from the legislative body, there would be an end of liberty, by reason the two powers would be united; as the same persons would sometimes possess, and would be always able to possess, a share in both.”
