Children become like the things they love.

At one year of age the child says his first intentional wordhis babbling has a purpose, and this intention is a proof of conscious intelligenceHe becomes ever more aware that language refers to his surroundings, and his wish to master it consciously becomes also greater.Subconsciously and unaided, he strains himself to learn, and this effort makes his success all the more astonishing.

By the age of three, the child has already laid down the foundations of his personality as a human being, and only then does he need the help of special scholastic influences. So great are the conquests he has made that one may well say: the child who goes to school at three is already a little man.

The environment must be rich in motives which lend interest to activity and invite the child to conduct his own experiences.
