"A border line is crossed when we allow lying and cheating beyond the expected. But even this seems a crucial skill in our lives: just imagine the violence and bloodshed that would result in academic life if we told our colleagues honestly what we think of the quality of their work. In this connection, parents think that their children are innocent little angels because they speak the truth all the time. But really, that is just a sign of lack of processing power and immaturity: rational agents at full capacity can handle mixtures of lies and truths with elegance and ease."
