Holding that there are “things” that possess existence and other “things” that don’t (unicorns) implies that ideas are primary.
It is useful to be able to separate the real world, horses, from the unreal, unicorns.
There is a material world in which the colour “blue” exists as a frequency of 606–668 THz and wavelength of 450-495 nm.
No. Electromagnetic radiation with those characteristics does exist. The “blue” is a mental construct applied to those photons when they arrive at our eyes. We see “blue” because certain cells in our retinas are excited while others are not. Had we evolved with black and white vision (as some animals have) then we would have no concept of “blue” any more than we have a concept of the ‘colour’ that birds see when they detect ultra-violet light.
The “blue” is not a property of the photons; it is a property of the structure of our retinas, and hence influences our mental models of the world which are inevitably influenced by our senses.
The other physical property of the colour blue has to do with retinal cone cell…
Yes. Blue is an internal human thing. All the exists externally is a particular range of wavelengths.
Colours are a constituent part of one’s personal relationship with the physical universe.
They are indeed “personal”. Someone who is red-green colour blind will see different colours from a tetrachromat who will see different colours from someone with standard vision. Because colours are personal, they have no intrinsic external existence, but are dependent on our specific sense organs.
It is not a reification to speak about God as the Being or Existence itself.
God exists. Therefore God has Being. Hence Being-of-God exists, therefore Being-of-God has Being. Hence Being-of-Being-of-God exists, therefore…
If there is only God, but not Being-of-God, then we can drop the whole infinite regress and agree that Being-of-X is a false reification for all values of X. It is enough to say “God exists” without all the logical problems caused by having a parallel “Being-of-God”.
You think we are talking about a thing, and when someone qualifies the matter and talks about no-thing you think that it means God doesn’t exist. You are failing to understand what is being said.
Read the Brahmajala sutta. Here is one of the gods talking about himself:
“I am the Brahma, the great Brahma, the conqueror, the unconquered, the
all-seeing, the subjector of all to his wishes, the
omnipotent, the maker, the
creator, the
supreme, the controller, the one confirmed in the practice of jhana, and
father to all that have been and shall be. I have created these other beings.”
I have highlighted a few words to help you see how this god might appear in Abrahamic scripture. I have no problem with the existence of God. I do have problems with some of the properties His human followers assign Him.
