George Eliot agreed with Comte and all other positivists in setting aside every inquiry into causes, and limiting philosophy to the search after laws. The idea of causes is idealistic, and a cause of any kind whatever is, according to these thinkers, not to be found. “The knowledge of laws,” says Comte, “is henceforth to take the place of the search after causes.” In other words, it is impossible for man to find out why anything is, he can only know how it is.
