Manifesto for a European Renaissance was written by a leader of the European New Right. It is a short excellent book. Below is a passage from the book that explains the need for free speech.
For Independence of Thought and a Return to the Discussion of Ideas
Incapable of renewing itself, powerless and disillusioned by the failure of its objectives, modern thought has slowly transformed itself into a form of ‘thought police’ whose purpose is to excommunicate all those who diverge in any way from the currently dominant ideological dogmas. Former revolutionaries have rallied around the status quo while carrying over a taste for purges and anathemas from their former lives. This new form of treachery relies upon the tyranny of public opinion, as fashioned by the media, and takes the form of cleansing hysteria, enervating mawkishness or selective indignation. Rather than trying to understand the approaching new century, they keep rehearsing outdated issues and recycling old arguments, which are nothing more than a means to exclude or to discredit opponents. The reduction of politics to the sound management of increasingly problematic growth excludes the possibility of radically changing society or even the possibility of an open discussion of the ultimate goals of collective action.
Democratic debate thus finds itself reduced to nothing. One no longer discusses, one denounces. One no longer reasons, one accuses. One no longer proves, one imposes. All thoughts, all writings suspected of ‘deviation’ or even of ‘drifting’ are represented as consciously or unconsciously sympathetic to ideologies that are held to be highly suspect. Incapable of developing their own ideas or even of refuting the ideas of others, these censors fight not only against stated opinions, but also against supposed intentions. This unprecedented decline of critical thought is still more aggravated in France by Parisian navel-gazing. Thus, we have come to forget the traditional rules of civilised debate. One also begins to forget that freedom of opinion, whose disappearance has largely been met with indifference, allows for no exceptions. Fearing free choice by the people and disdaining their aspirations, one prefers the ignorance of the masses.
The New Right advocates a return to critical thinking and strongly supports total freedom of expression. Faced with censorship, ‘disposable’ ideas and the futility of passing fads, the New Right insists, now more than ever, on the need for a true renewal of critical thinking. The New Right advocates a return to debating issues, freed from the old divisions and fixed positions which block new approaches to old problems as well as new syntheses. The New Right calls all free minds to join in a common front against the disciples of Trissotin, Tartuffe, and Torquemada.
