Oh dear, thanks wisdom, don't know if I can keep up, will take one at a time.
To begin with, salt is an indeterminate truth. On the tongue, its salty. In a wound, its pain. For a slug, its death. For sea creatures its part of their natural environment. For the stomach, its a cause for illness. Hence, even the thing we call salt, due to its compounded nature, is found to be indeterminate.
Salt is the only constant in your examples. The only "indeterminate" here is what you mix it with.
If we narrow it to the tongue, and just the experience of "saltiness" that is still indeterminate. What is enough salt for me, is too much for you and too little for someone else. Even for you, what is too much salt today, might taste good tomorrow if you are craving it, and might be just right the next day.
"Enough" and other adjectives are subjective, salt is still salt.
The experience of saltiness arises purely as a result of a number of compounded entities. The salt itself (sodium chloride) coming into contact with the compounded entity of the tongues taste buds. That in turn is translated into electrical impulses which reach the brain, causing electro-chemical reactions, all of which are compounded entities, arising due to Dependent Arising, and lacking inherent existence. This is all experienced by the mind, and when the mind is delusional, it also is a compounded entity, with a belief in the existence of a self who experiences saltiness.
Agreed. Our experiencing of salt or saltiness is a complex process.
So saltiness is not only an indeterminate truth, meaning we cant even peg down what "saltiness" really is, but it arises entirely within conditions which are compounded phenomena, made up of other phenomena, and ultimately upon examination all these phenomena are discovered to be empty. The meaning of Dependent Arising is more or less this, that things appear to arise, they appear to abide, they appear to cease. They relate to one another in a relative, limited, indeterminate and conventional way. However all of it, the entire display, is just an illusion, like a dream, or the moon in water, it has no inherent and lasting existence.
I think we pegged saltiness to the interaction of salt molecules with a tongue earlier. I concur with your dependent arising points, I love dependent arising. Your final comment borders on antirealism so would need to explore further before commenting.
Furthermore saltiness only exists in a specific compounded form interacting with another specific compounded form. Sodium or Chlorine by themselves are both deadly poisons, which are in turn just arrangements of protons, electrons and neutrons, which are in turn just arrangements of sub atomic particles, quantum particles, mathematical abstractions, and finally they are realized to be completely empty.
Right, but this is why we stopped looking for salt beyond a salt molecule earlier because all the smaller stuff isn't salty.
What does it mean to say "salt exists conventionally"? It means that salt exists only relative to other conventional, compounded entities. To admit of a things conventional existence is the same as saying that it does not exist at all. Why? Because once we are making a distinction that something is conventional, we are also acknowledging that ultimately it has no absolute, inherent reality. This does not mean that conventionally the salt is "non existent", it means precisely what it says. Salt only exists as a compounded, indeterminate and temporary appearance whose nature is emptiness.
I have taken issue with the "does not exist at all" part, am not sure these unqualified "exist" terms referring to some ultimate inconceivable are helpful or even relevant to external phenomena.
People want to nitpick the idea that "it exists" conventionally as meaning somehow that someone is saying "it exists absolutely". Whats happening though is that people are taking the word "exist" to always indicate absolute existence. Thats why we modify our meaning with the words "conventional" and "absolute" or "inherent" so as to be clear that we are not making a claim that would fall into Eternalism, the idea that salt is an inherently existent entity which has some kind of eternally existing quality called "saltiness".
Yes. We asked earlier how "absolute existence" was a helpful concept if it contained nothing, like an empty set.
