As a nihilist my sense of meaning seams to be compatible to yours. I don't deny that we can come up with all sorts of meanings but the point is that there is no intrinsically higher meaning to everything, it's all made up. In fact, the awareness of this is the basis of my nihilism. That doesn't mean, that I don't like some meanings more than others, otherwise I had no reason to act whatsoever.

There are certainly universal truths. For example, you exist. Therefore there is something to believe in

[vidarh]

Only in the most abstract sense is even that true. I know that I have existence in this very moment. I don't know that I existed a moment ago, for that could be an illusion. I don't know what my existence is, because my senses could be an illusion. I don't know that I have any existence past this moment because that is a belief based in a memory of time passing, which could be an illusion. I can't tell whether time exists, or space exists, because they're all dependent on my senses and a memory I can't trust.

For what I know, my "existence" could be an infinitely short moment, or even an entirely static endless "moment", or any of an infinite variety of other options.

So even most of existence is only assumption. It's a set of assumptions that makes sense to just accept because we have no way of proving otherwise, but they are assumptions, not "universal truths".

If one thinks about it, even basic truth may not be so evident.

For example, consider Cogito, ergo sum. As Latin has no continues verb time, that phrase may mean I exist because I think. Or I am existing because I am thinking . The latter implies that when one stops thinking the existence stops, the opposite of the former. Philosophers still debates what exactly Descartes meant.

Or consider the notion of time flow. In 1908 John MacTaggart published a paper arguing that the feeling of time flow is unreal. Again, there are heavy debates about the validly of his arguments without any conclusion with quite a lot of philosophers accepting the argument and even arguing that the time flow is an illusion.

My existence is negligible, especially in the grand scheme of things.
