Here is another site where the author has made an attempt to verify this quote. It appears to be an intelligent and sober attempt to find truth: http://www.notnews.org/philosophy/dewey-think-for-themselves/ I too do not like to be led down a rosy path by either side. Truth has no agenda.

The author at this site does include quotes by Dewey, with sources, which do not comport with the quote in question.
