Song Meaning
The lyrics paint a stark picture of human existence, where the inherent instability of mortal things is the sole cause of our shifting fortunes. What makes us happy today can just as easily lead to misery tomorrow, a constant cycle of gain and loss. This mutability means that the very things that bring us joy are also the source of our future sorrow.
This creates a profound emotional tension: the narrator suggests that true understanding lies in recognizing this impermanence. Because happiness is fleeting and sorrow inevitable, one who grasps this truth should not judge their present suffering too harshly. The pain experienced is a natural consequence of life's inherent instability, not a personal failing.
The central craft here is the direct equation of "inconstanzia" (inconstancy) with the root of all human suffering and joy. The lyrics state plainly that this instability "Cagion è sola" (is the sole cause) of both happiness and misery. This direct assertion, rather than relying on metaphor, gives the argument a philosophical weight, presenting a clear cause-and-effect relationship for the human condition.
Ultimately, these lyrics resonate because they offer a framework for understanding unavoidable pain. By positing that our troubles stem from the very nature of impermanence – the fact that "quel che n'invola il bene / Anche ce'l rende" (what steals good from us / Also returns it) – the writing provides a form of solace. It suggests that acceptance of this constant flux, rather than resistance, is the path to a more measured perspective on our own grief.
