I didn’t ask without reason. Notice the paradox.
We know that water exists. How do we know water? How can we even say anything about water?
We know water only through its encounter with something else: for example, when we pour water on a fire, we know that water turns into steam and extinguishes the fire. Or when we immerse our hand in water, we discover other properties of water (wetness, heat conductivity, etc.).
It turns out that knowledge itself is only possible through the encounter of something with something else.
But what about being? How can we know being? With what can we encounter being if we can’t jump out of it? And secondly: logically, to know being, we need non-being. Somehow, we must encounter them. But how can we encounter being with that which doesn’t exist (remember, “being is, and non-being is not”)?
Of course, Heidegger encountered it with death. But there are several limitations here. For example, we can’t be 100 percent certain that after our death there is nothingness. And secondly, after death we can’t return to recount what happened there. So, by confronting being with death, Heidegger only theoretically approached the idea. But not in fact. We are still deprived of the means to understand being because we have nothing to compare it to.
Okay, we can say, here’s a sheep—it’s alive. Let’s kill it and see what happens. We kill the sheep, and it stops moving. Its body begins to decompose and ceases to hold together as a coherent object. Does this mean that nothingness (or death) is the cessation of everything? Unfortunately, this is again just an assumption. The sheep itself may have ended up in nothingness, but being itself has lost nothing: with the sheep’s death, it merely became food for worms.
Thus, when speaking about being, I see only problems and nothing definitive…
