The second half of your program will destroy the first half

From Selected Essays on Political Economy by Frederic Bastiat.

Here I come into conflict with the most popular prejudices of our day. People not only want the law to be just; they also want it to be philanthropic. They are not satisfied that justice should guarantee to each citizen the free and inoffensive exercise of his faculties for his physical, intellectual, and moral development; they require of it that it should directly spread welfare, education, and morality throughout the country. This is the seductive aspect of socialism.

But, I repeat, these two functions of the law contradict each other. We must choose between them. A citizen cannot at the same time be free and not free. M. de Lamartine wrote me one day: "Your doctrine is only the half of my program; you have stopped at liberty; I go on to fraternity." I answered him: "The second half of your program will destroy the first half." And, in fact, it is quite impossible for me to separate the word "fraternity" from the word "voluntary." It is quite impossible for me to conceive of fraternity as legally enforced, without liberty being legally destroyed, and justice being legally trampled underfoot.

Legal plunder has two roots: One, as we have just seen, is in human selfishness; the other is in false philanthropy.
