ray bradbury

I am looking for the sources for two highly quoted but (as far as I can tell) never cited quotations. I prefer to have the original source - that could be journal article, newspaper article, interview, authored work, etc. but I can accept a reference to a reputable quotations dictionary or other reference work. I need page number in addition to the title, publisher, etc.

The first quote is:

You don't have to burn books to destroy a culture. Just get people to stop reading them.
~Ray Bradbury

The second quote is:
If large numbers of people believe in freedom of speech, there will be freedom of speech even if the law forbids it. But if public opinion is sluggish, inconvenient minorities will be persecuted, even if laws exist to protect them.

~George Orwell
