Knowledge is justified belief.

We need to conceive of ourselves as "agents" impelled by self-generated intentions.

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.

We carry with us habits of thought and taste fostered in some nearly forgotten classroom by a certain teacher.

We cannot, even given our most imaginative efforts, construct a concept of Self that does not impute some causal influence of prior mental states on later ones.

Teaching is the canny art of intellectual temptation

Understanding something in one way does not preclude understanding it in other ways.
