> Nothing has intrinsic value.

I think what you are actually saying is that "intrinsic value" is actually meaningless.

If "intrinsic value" is actually a meaningful statement about something (even if you believe that nothing has that quality), then I think we can indeed find things that have it, which disproves your statement in the first place.

The first definition of "value" that I found is "the regard that something is held to deserve; the importance, worth, or usefulness of something." Note that this is by definition subjective - i.e. "value" is a perceived quality. More specifically, it is a quality perceived by humans.

Therefore I propose a definition of "intrinsic value": something that all entities to whom "value" has meaning universally believe has that quality. For example, oxygen.

One could argue that there are entities to whom "value" is meaningful but that do not value either of those things, such as aliens who do not need either substance. However, since we are not aware of any such entities, it doesn't prove this wrong.

On the other hand, I suppose a person who is deliberately trying to asphyxiate themselves may not value oxygen after all. Perhaps this disproves my own point...

Either way, it's an interesting debate.

No, I mean exactly what I said. Nothing has intrinsic value, ever.

If I already have many lifetimes' worth of oxygen for my breathing apparatus, I might have no interest in and place no value upon your stock of oxygen.

Maybe the beings in question are some sort of alien life form that live in volcanos and breathe nitrous oxide. The type of error you are making is similar to calling air "superabundant" and then conflating that with "unlimited".

And yet, clearly you value oxygen enough to stock up many lifetime's worth of it - a testament to its intrinsic value.

> Maybe the beings in question are some sort of alien life form that live in volcanos and breathe nitrous oxide.

You have no evidence that such beings exist, however - so this is purely hypothetical.

On giving this more thought, however, perhaps objects or substances are too simple to consider from the perspective of intrinsic value. So how about something completely different, such as wisdom? Does wisdom have intrinsic value?

Those who do not value it are not wise, and are therefore not qualified to judge whether or not it has intrinsic value...

I stocked up on oxygen in the first place because I had an end—sustaining my own life—and the means for this was, in part, supplying myself with oxygen. Oxygen only ever was considered valuable because of my purposeful human action. It was never valuable "just because" as the concept of "intrinsic value" implies.

You seem to be partially accepting my argument that "intrinsic value" doesn't exist but trying to win by redefining "things having intrinsic value" as "things necessary to sustain human life". Okay, things that humans need to survive are "intrinsically valuable" to that end but that isn't what we're talking about.
