"I believe that we violate the child's nature and render difficult the best ethical results, by introducing the child too abruptly to a number of special studies, of reading, writing, geography, etc., out of relation to this social life. Ibelieve, therefore, that the true centre of correlation of the school subjects is not science, nor literature, nor history, nor geography, but the child's own social activities” (Dewey, 1897, 5).
