If liberty means anything at all it means the right to tell people what they do not want to hear. The common people still vaguely subscribe to that doctrine and act on it. In our country — it is not the same in all countries: it was not so in republican France, and it is not so in the USA today — it is the liberals who fear liberty and the intellectuals who want to do dirt on the intellect: it is to draw attention to that fact that I have written this preface.
[..] intellectual freedom is a deep-rooted tradition without which our characteristic western culture could only doubtfully exist. From that tradition many of our intellectuals are visibly turning away. They have accepted the principle that a book should be published or suppressed, praised or damned, not on its merits but according to political expediency. And others who do not actually hold this view assent to it from sheer cowardice.
