Protection.

Protection of freedom of thought requires that no group should be permitted by law to express an opinion. For when a group starts having opinions, it inevitably tends to impose them on its members. Sooner or later, these individuals find themselves debarred, with a greater or lesser degree of severity, and on a number of problems of greater or lesser importance, from expressing opinions opposed to those of the group, unless they care to leave it. But a break with any group to which one belongs always involves suffering—at any rate of a sentimental kind. And just as danger, exposure to suffering are healthy and necessary elements in the sphere of action, so are they unhealthy influences in the exercise of the intelligence. A fear, even a passing one, always provokes either a weakening or a tautening, depending on the degree of courage, and that is all that is required to damage the extremely delicate and fragile instrument of precision which constitutes our intelligence. Even friendship is, from this point of view, a great danger. The intelligence is defeated as soon as the expression of one’s thoughts is preceded, explicitly or implicitly, by the little word "we." And when the light of the intelligence grows dim, it is not very long before the love of good becomes lost.
