"A child is protected by the limit of feebleness against emotions which are too complex. He sees the fact, and little else beside. The difficulty of being satisfied by half-ideas does not exist for him. It is not until later that experience comes, with its brief, to conduct the lawsuit of life. Then he confronts groups of facts which have crossed his path; the understanding, cultivated and enlarged, draws comparisons; the memories of youth reappear under the passions, like the traces of a palimpsest under the erasure; these memories form the bases of logic, and that which was a vision in the child's brain becomes a syllogism in the man's."
