Another mind-body duality?

The Wave Theory of Economics
Setting: A quiet, timeless space overlooking a vast, rolling ocean. The waves are a constant, rhythmic presence.
Characters:
- Sophia: Calm, poised, radiating a gentle understanding.
- Marcel: Thoughtful, sensitive, with a pensive gaze.
Sophia: Welcome, Marcel. You've spent a great deal of time observing the intricate movements of the human heart, haven't you?
Marcel: I have. And I've found that the richest tapestry of thought, the clearest view of ourselves, often doesn't come during times of smooth sailing. It arrives when the seas are rough.
Sophia: Exactly. Look at the ocean, Marcel. We call this the "Wave Theory of Economics," but it’s a theory of everything, really. If we were to measure the prosperity of a person's life—or an entire society—we might be tempted to only count the high crests, those moments of joyous, effortless success.
Happiness is beneficial for the body, but it is grief that develops the powers of the mind.
— Marcel Proust (1871-1922)
Marcel: But that would be a shallow calculation. The easy current of contentment keeps the body and spirit healthy, yes, but it’s the profound sorrow, the weight of loss, that truly forces the intellect to stretch, to adapt, to build a more complex internal structure. We learn to navigate by starlight when the sun isn't shining.
Sophia: The economic analogy is simple: A downturn, a period of hardship—the trough of the wave—is not merely a destruction of value; it is a forced refinement. It strips away the unsustainable, the complacent, the unnecessary. It pushes innovation and sharpens efficiency, compelling new solutions that would never have been considered in the comfortable inertia of a boom. The systems become smarter, more resilient.
Marcel: So, the wisdom gained from grief is the true engine of progress, in a personal life as well as in the marketplace. The sadness of yesterday lays the foundation for a more insightful, more powerful "recovery" tomorrow. It's the cycle of contraction leading to a more robust expansion. The mind develops in the struggle.
Sophia: Precisely. The joy brings energy to the system, but the challenge brings intelligence. We must remember that the greatest strength is forged in the downward sweep of the wave. You’ve seen this truth in the soul, and it manifests in all of our endeavors, even in the cold logic of markets. The wave must crash for the next one to form higher.
