To Understand Is To Invent.

Experience Precedes Understanding.

What Is Desired Is That The Teacher Ceased Being A Lecturer, Satisfied With Transmitting Ready-made Solutions. His Role Should Rather Be That Of A Mentor Stimulating Initiative And Research.

Children Have Real Understanding Only Of That Which They Invent Themselves, And Each Time That We Try To Teach Them Too Quickly, We Keep Them From Reinventing It Themselves.

Play Is The Work Of Childhood.

Each Time One Prematurely Teaches A Child Something He Could Have Discovered Himself, That Child Is Kept From Inventing It And Consequently From Understanding It Completely.
