h regulate the behaviour of those about him, to reject
beliefs which they hold, to see better ways of life than those they
follow, it is almost

[8] impossible for him, if he is convinced of the truth of his own
reasoning, not to betray by silence, chance words, or general attitude
that he is different from them and does not share their opinions. Some
have preferred, like Socrates, some would prefer to-day, to face death
rather than conceal their thoughts. Thus freedom of thought, in any
valuable sense, includes freedom of speech.

At present, in the most civilized countries, freedom of speech is taken
as a matter of course and seems a perfectly simple thing. We are so
accustomed to it that we look on it as a natural right. But this right
has been acquired only in quite recent times, and the way to its
attainment has lain through lakes of blood. It has taken centuries to
persuade the most enlightened peoples that liberty to publish one's
opinions and to discuss all questions is a good and not a bad thing.
Human societies (there are some brilliant exceptions) have been
generally opposed to freedom of thought, or, in other words, to new
ideas, and it is easy to see why.

The average brain is naturally lazy and tends to take the line of least
resistance. The mental world of the ordinary man consists of beliefs
which he has accepted without questioning and to which he is firmly
attached; he is instinctively hostile to anything which

[9] would upset the established order of this familiar world. A new
idea, inconsistent with some of the beliefs which he holds, means the
necessity of rearranging his mind; and this process is laborious,
requiring a painful expenditure of brain-energy. To him and his fellows,
who form the vast majority, new ideas, and opinions which cast doubt on
established beliefs and institutions, seem evil because they are
disagreeable.

The repugnance due to mere mental laziness is increased by a positive
feeling of fear. The conservative instinct hardens into the conservative
doctrine that the foundations of society are endangered by any
alterations in the structure. It is only recently that men have been
abandoning the belief that the welfare of a state depends on rigid
stability and on the preservation of its traditions and institutions
unchanged. Wherever that belief prevails, novel opinions are felt to be
dangerous as well as annoying, and any one who asks inconvenient
questions about the why an
