Both were critical of capitalism, and while Fourier is usually a punchline in history classes because he believed that in his ideal socialist world, the seas would turn to lemonade, he was right that human beings have desires that go beyond basic self-interest and that we aren't always economically rational actors. The other French socialists were the revolutionaries, and they saw the French Revolution, even its violence, in a much more positive light. The most important of these revolutionaries was Auguste Blanqui, and we associate a lot of his ideas with communism, which is a term that he used. Like the utopians, he criticized capitalism, but he believed that it could only be overthrown through violent revolution by the working classes. However, while Blanqui thought that the workers would come to dominate a communist world, he was an elitist. And he believed that workers could never on their own overcome their superstitions and their prejudices in order to throw off bourgeois oppression. And that brings us to Karl Marx, whose ideas and beard cast a shadow over most of the 20th century.
