“Metaphors are powerful. No matter how subtle and sophisticated we would like to believe we are in our thinking, basic visual or tactile images create the very foundations of our thought. Compared to clockwork images of economies, the metaphor of ‘the economy as a beating heart’ seems to be particularly apt. The heart has a particular physical structure (valves and chambers) and regularity of functioning. Imagining the economy as a heart recognizes that it also has structures (institutions) and regularities, which is not different from imagining it as a machine. But because the heart is a living, vital organ, additional highly relevant insights flow from this metaphor.
