What’s the difference between a proposition that is time-indexed and one that isn’t?

Time, that enigmatic force that governs our existence, plays a crucial role in shaping the way we perceive reality. When we think of propositions that are time-indexed, we are confronted with the notion that truth is not a static concept, but rather one that is subject to the ever-changing tides of time. A proposition that is time-indexed carries with it a sense of temporality, of being situated within a particular moment in history. It speaks to the impermanence of all things, reminding us that what may be true now may not hold true in the future.

On the other hand, a proposition that is not time-indexed seems to transcend the limitations of time, existing outside of its grasp. It speaks to a sense of universality, of truths that are eternal and unchanging. In this sense, it is easy to see why time-indexed propositions can be seen as more dynamic and fluid, while non-time-indexed propositions may be viewed as more stable and enduring.

But one must ask, does the absence of a time index truly render a proposition timeless? Or is it simply a tool we use to simplify our understanding of complex ideas? Perhaps the distinction between time-indexed and non-time-indexed propositions is not as clear-cut as we may think. After all, even the most seemingly timeless truths are subject to the ravages of time, as our perceptions and interpretations of the world around us are constantly evolving.

In the end, the difference between a proposition that is time-indexed and one that isn't lies not in their inherent truth value, but in their ability to reflect the transient nature of existence. Time serves as a reminder that all things are in a state of constant flux, and that our understanding of reality is always in flux as well. As Nietzsche famously said, "Only ideas obtained from walking have any value.” And so, let us continue to walk the winding path of existence, exploring the depths of time and truth with an open mind and an unshakeable spirit.
