In the first place how did we arrive at the concept of ‘atoms’?
The existence of atoms are framed by a human-based Framework and System, i.e. the Scientific Framework and System.
Therefore the existence of atoms are grounded on the subjects collectively.
Do atoms really exist by themselves per-se?
No! atoms are merely clusters of sub-atomic particles some moving at great speed within a nucleus.
The existence of sub-atomic particles are framed by a human-based Framework and System, i.e. the Scientific Framework and System.
Therefore the existence of sub-atomic particles are grounded on the subjects collectively.
There is no way you can deny the above knowledge and its logic.
Thus no matter what the ultimate matter that is to be discovered by Science, it will be grounded on the subjects collectively, i.e. the human-based Scientific Framework and System!
Therefore there is no pre-existing objects, i.e. objects that exist as absolutely independent from the conditions of humans [subjects].
Now when objects and things emerged onto the consciousness of humans, they arise in alignment with certain pre-existing algorithms within the human brain most via Nature [DNA] and nurture [RNA].
This is why you see an apple which rots subsequently.
A bacteria or fungus do not ‘see’ such “an apple which rots subsequently” like ALL normal humans do.
Why? because a bacteria or fungus has different pre-existing inherent algorithms in their central nervous systems.
Is there something constant or permanent that all living things will cognize as the same universally? None!
Therefore whatever the reality, it is always subject[s]-interdependent.
Your urge to reify objects out there as you/&others want them to be is due to a terrible psychology and instinct within.
You could say that rotten apple emerged. But the rotten apple emerged as a consequence of its past interactions, on what pre-existed the rotten apple, which was an ordinary apple and an environment in which an apple rots.
That is what Hume argued, i.e. the reality of cause and effect is pure psychology due to customs and habit of constant conjunction.
Hume did not understand “certain pre-existing algorithms within the human brain most via Nature [DNA] and nurture [RNA],” then.
Objects exist independently of subjects, yes. The external world isn’t driven by subjects. Species constantly go extinct and the external world continues existing. The external world isn’t dependent on being observed by humans or any other species or any particular living organism for its existence. The ideas of objects are dependent for existence on human minds, but what the ideas refer to, objects themselves, are not, unless they are artifices - objects created and maintained by humans, but then again, they are not ONLY dependent on human perception, but also on human action to maintain those artifices. Moreover, neither objects nor ideas emerge spontaneously. There is a pattern to their emergence.
Your thinking is too superficial and confined to conventional and one narrow perspective.
Note I mentioned emergence based on “certain pre-existing algorithms within the human brain most via Nature [DNA] and nurture [RNA],” and driven by psychology grounded on the survival instinct.
Subjectivism is a very useful tool in controlling the masses. If you manage to convince others that there is no external world independent of humans, and that reality is dependent on human minds, you can also effectively indoctrinate them into being dependent on what YOU say is the truth about objects, and since there is no external, independent standard that we all share (REALITY) according to this position, others are helpless as they have nothing to appeal to defend themselves with except their own subjectivity. However, usually those in power will try to enforce their own particular kind of subjectivity as superior, making themselves the “authority” on the matter where what they say is “officially approved fact” while what you say is “just your opinion, man”, regardless of what is actually true. They have successfully convinced you you cannot access the objective world yourself, using your own mind and senses, but that you need the validation of others, most likely some authority, telling you what is or isn’t true. Truth stops being based on the objective, external world, and starts being based on the subjective thoughts about the objective world of people or groups of people, such as scientists. These statements MAY be actual truths and based on accurate observations of the objective world (if they followed the scientific method without error), or they can be lies told to be truths, either because of a mistake in reasoning, or intentional and for the sake of accomplishing social/political goals or avoiding condemnation.
Apparently you have been brainwashed to fear evil ideological systems.
I am not into subjectivism nor any ‘ism.’
The most realistic fact is reality is grounded on the subject[s] interdependently and collectively.
All your fears of evil ideologies and ‘-isms’ including your own can be mitigated and modulated by a sound Framework and System of Morality and Ethics to ensure optimal well being for humanity. Many people focus too much on objects or subjects but forgot about Morality and Ethics.
Your sort of independent external objectivity is merely a shade nearer to the ontological objectivity of a God and from this view you lose contact and control of reality.
From the realistic of a collective-subjective reality which is driven by ‘subjects’ collectively, it open up the opportunity for subjects - in entanglement with the reality they are a part of -to control their destiny from a collective basis which is shared and gelled by Philosophy-proper. [Morality and Ethics being primary].
Philosophically the only way you can align your independent external reality is to rely on the Correspondence Theory of Truth without even knowing whether there a parallel reality on the other side.
