Which of the following is true as per the passage?

Passage:
Socialism, whatever may be its more exact definition, stands for an organisation of society, and more especially for an economic organisation, radically opposed to, and differing from, the democratic organisation which prevails to-day. So much we may take for granted; but here, before going further, it is necessary to free ourselves from a very common confusion. When socialism, as thus defined, is spoken of as a thing that exists, two ideas are apt to suggest themselves to the minds of all parties equally, of which one coincides with facts, while the other does not, having, indeed, thus far at all events, no appreciable connection with them; and it is necessary to get rid of the false idea, and concern ourselves only with the true.
The earlier socialistic thinkers may be fairly regarded as accurate and original critics. The so-called orthodox economists of the school of Mill and Ricardo accepted the capitalistic system as part of the order of nature, and their object was mainly to analyse the peculiar operations incident to it. We must make sure we understand, for there is cant in Socialism, just as there is in religion, and there is good reason to fear many of us go on using these good mouth-filling phrases, "Materialistic Conception of History," "Class-Conscious Proletariat," "Class Struggle," and "Revolutionary Socialism," Theoretical Socialism of a logical and thoughtful kind, not entangled with Radicalism, has made much progress of late years, more specially, so far as my own experience goes, in the educated and professional classes. That is a different spirit from the buoyant expectancy of the old Liberalism.
