even in the most advanced societies, where they have no longer the power
to arrest development or repress the publication of revolutionary
opinions. We still meet people who consider a new idea an annoyance and
probably a danger. Of those to whom socialism is repugnant, how many are
there who have never examined the arguments for and against it, but turn
away in disgust simply because the notion disturbs their mental universe
and implies a drastic criticism on the order of things to which they are
accustomed? And how many are there who would refuse to consider any
proposals for altering our imperfect matrimonial institutions, because
such an idea offends a mass of prejudice associated with religious
sanctions? They may be right or not, but if they are, it is not their
fault. They are actuated by the same motives which were a bar to
progress in primitive societies. The existence of people of this
mentality, reared in an atmosphere of freedom, side by side with others
who are always looking out for new ideas and

[12] regretting that there are not more about, enables us to realize
how, when public opinion was formed by the views of such men, thought
was fettered and the impediments to knowledge enormous.

Although the liberty to publish one’s opinions on any subject without
regard to authority or the prejudices of one’s neighbours is now a well-
established principle, I imagine that only the minority of those who
would be ready to fight to the death rather than surrender it could
defend it on rational grounds. We are apt to take for granted that
freedom of speech is a natural and inalienable birthright of man, and
perhaps to think that this is a sufficient answer to all that can be
said on the other side. But it is difficult to see how such a right can
be established.
