Keynes also noted that, "Even apart from the instability due to speculation, there is ... instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than mathematical expectations... [Most] of our decisions to do something positive... can only be taken as the result of animal spirits — a spontaneous urge to action rather than inaction, and not as the outcome of [reasoned decisions based on weighing the data]." -- The General Theory Of Employment, Interest, And Money (1936) I'd say there's plenty of Animal going on, out there, just now. And more to come.
