Many of the most significant goods in human life are fleeting, fragile, and subject to loss. But this aspect of such goods, what I call their preciousness, is undertheorized. Here I provide an account of the nature of precious goods, and argue that this category of goods is significant. I argue that while the preciousness of goods is not a consistent contributor to their intrinsic value, preciousness nevertheless calls for a distinct attitudinal response on the part of rational agents: a focused, joyful attention I refer to as cherishing.
