It is with children that we have the best chance of studying the development of logical knowledge, mathematical knowledge, physical knowledge, and so forth.

Experience precedes understanding.

Only education is capable of saving our societies from possible collapse, whether violent, or gradual.

Logical positivists have never taken psychology into account in their epistemology, but they affirm that logical beings and mathematical beings are nothing but linguistic structures.

During the earliest stages the child perceives things like a solipsist who is unaware of himself as subject and is familiar only with his own actions.

The more we try to improve our schools, the heavier the teaching task becomes; and the better our teaching methods the more difficult they are to apply.

The principle goal of education in the schools should be creating men and women who are capable of doing new things, not simply repeating what other generations have done.
