We begin with the hypothesis that any subject can be taught effectively in some intellectually honest form to any child at any stage of development.

Being able to "go beyond the information" given to "figure things out" is one of the few untarnishable joys of life.

Teaching is the canny art of intellectual temptation

Education must, be not only a transmission of culture but also a provider of alternative views of the world and a strengthener of the will to explore them.

In the perception of the incongruous stimuli, the recognition process is temporarily thwarted and exhibits characteristics which are generally not observable in the recognition of more conventional stimuli.

In time, and as one comes to benefit from experience, one learns that things will turn out neither as well as one hoped nor as badly as one feared.

Good teaching is forever being on the cutting edge of a child's competence.
