I have done a word search and quotation search through a number of Dewey's works, and several critical editions on Amazon and have not found this quote. That does not mean that it does not exist, it could be from a letter or more obscure work. However, it may be another author's summary of a Dewey idea, which would make it an interpretation, or it may be someone else's quote mistakenly or falsely attributed.

I would like a proper attribution to the quote: which work of Dewey's? Edition and page number are helpful if not required, although to make such a quote in a scholarly work does require them so that others can verify the quote. This is not a matter of agreement or disagreement with Dewey, so much as it is honesty in the attribution.
