Intelligence is what you use when you don't know what to do. - Jean Piaget

I am convinced that there is no sort of boundary between the living and the mental or between the biological and the psychological. From the moment an organism takes account of a previous experience and adapts to a new situation, that very much resembles psychology.

The majority of parents are poor psychologists and give their children the most questionable moral trainings. It is perhaps in this domain that one realized most how keenly how immoral it can be to believe too much in morality, and how much more precious is a little humanity than all the rules in the world. Thus the adult leads the child to the notion of objective responsibility, and consolidates in consequence a tendency that is already natural to the spontaneous mentality of little children.

In real life the child is in the presence, not of isolated acts, but of personalities that attract or repel him as a global whole. He grasps people's intentions by direct intuition and cannot therefore abstract from them. He allows, more or less justly, for aggravating and attenuating circumstances. This is why the stories told by the children themselves often give rise to different evaluations from those suggested by the experimenter's stories.
