What are the differences between unlimited child theory and tabula rasa?

Answer 1

The "Educationalists" believed that children were born as "blank slates", beginning their lives morally neutral. From this point of view, infants were neither inherently good or inherently evil. A child's nature and personality would develop over childhood, a period of time during which the educationalists believed a child was particularly impressionable. Adults surrounding a child could potentially have a very lasting effect on his personality.

Among the competing philosophies characterizing children and their education was the notion that innate internal forces were the driving forces of the development of a child. This idea rested upon the view of the child as emerging from the womb with an intrinsic goodness and with all the faculties to begin his own development. Conversely, institutions, "that barbarous method of education," sapped the individuality and curiosity of the child, defining a child within unnatural boundaries.
