This great quotation from Kierkegaard is plastered all over the Internet:
'People demand freedom of speech to make up for the freedom of thought which they avoid.'
Yet none of the places I've seen it quoted gives a source. I went through five pages of Google references to this without finding one. This may be because it spun off from a single unquoted origin on someone's webpage...or, more worryingly, it may be a symptom of how people are using the medium. Can anyone give me chapter and verse?
