"This book has argued that it is possible to gather and to analyze numbers in ways that help us understand the world. But it has also argued that very often we make mistakes not because the data aren’t available, but because we refuse to accept what they are telling us. For Irving Fisher, and for many others, the refusal to accept the data was rooted in a refusal to acknowledge that the world had changed. [Moi ici: Recordo logo Drop your tools!!! Ou porque não era o verdadeiro socialismo]
...
One of Fisher’s rivals, an entrepreneurial forecaster named Roger Babson, explained (not without sympathy) that while Fisher was “one of the greatest economists in the world today and a most useful and unselfish citizen,” he had failed as a forecaster because “he thinks the world is ruled by figures instead of feelings.” [Moi ici: Recordo logo "Nós fazemos as contas ao contrário"]
I hope that this book has persuaded you that it is ruled by both." [Moi ici: Recordo logo Acerca do optimismo não documentado]
