The brain of man is, especially in infancy, like a soft wax, ready to
receive all the impressions we wish to make on it; education furnishes
nearly all his opinions, at a period when he is incapable of judging for
himself. We believe that the ideas, true or false, which at a tender age
were forced into our heads, were received from nature at our birth; and
this persuasion is one of the greatest sources of our errors.
