The following quote hit like a ton of bricks. Especially since it's written in 1995 and still rings true; even more so.
“We've arranged a global civilization in which most crucial elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.” —Carl Sagan
“It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment.” —Carl Friedrich Gauss
"If teaching is reduced to mere data transmission, if there is no sharing of excitement and wonder, if teachers themselves are passive recipients of information and not creators of new ideas, what hope is there for their students?" —Paul Lockhart, A Mathematician's Lament: www.maa.org/external_archive/devlin/LockhartsLament.pdf
