Teaching and research are not to be confused with training for a profession. Their greatness and their misfortune is that they are a refuge or a miss… - Claude Lévi-Strauss

Not only does a journey transport us over enormous distances, it also causes us to move a few degrees up or down in the social scale. It displaces us physically and also — for better or for worse — takes us out of our class context, so that the colour and flavour of certain places cannot be dissociated from the always unexpected social level on which we find ourselves in experiencing them.

Scientific knowledge advances haltingly and is stimulated by contention and doubt.

Logically, the "infantilization" of the culprit implied by the notion of punishment demands that he should have a corresponding right to a reward, in the absence of which the initial procedure will prove ineffective and may even lead to results contrary to those that were hoped for. Our system is the height of absurdity, since we treat the culprit both as a child, so as to have the right to punish him, and as an adult, in order to deny him consolation; and we believe we have made great spiritual progress because, instead of eating a few of our fellow-men, we subject them to physical and moral mutilation.
