  • “…the complexity of the real world can best be

tamed by seeing things in the round, as a whole. Only by taking a broad view can we avoid the twin dangers of a silo mentality – in which a fix 'here' simply shifts the problem to 'there' – and

gives rise to a much bigger problem to fix 'later.'”
