Quote by Paul Wallace
Most of what we believe, we believe because it was told to us by someone we trusted. What I would like to suggest, however, is that if we rely too much on that kind of education, we could find in the end that we have never really learned anything.
As far as I know, the original source of this quote is on Paul Wallace’s blog. This quote also appears in the introduction of the book A TeXas Style Introduction to Proof by Ron Taylor and Patrick Rault. A Facebook post by David Failing introduced me to this wonderful quote.
