ob·jec·tive
əbˈjektiv/
adjective
adjective: objective
1.
(of a person or their judgment) not influenced by personal feelings or opinions in considering and representing facts.
But I fail to understand how you can hold these views and then claim (assuming I'm understanding correctly) that we can actually be objective.
Try and change your feelings or opinion about gravity and thus not be subject to it's effects. See if other observers have gravity exerted upon them, find one who is not and you have made your case.
So if a dream character declares "All things are subjective" was it an objective claim?
You cannot refer to a dream without saying that objective reality exists, for a dream only exists in contrast to objective reality, a dream is unreal, but if reality was a dream, a dream would be indistinguishable from reality, yet even when it appears thus, we awaken and it is not reality, likewise in the most real dream I have ever had there were significant differences between it and reality, observable differences. I actually had a dream that seemed rather real the other week, and in it I could not remember how i got to this location and it occurred to me that i
might be dreaming because as real as it seemed there were issues with it when compared to reality, and I said in the dream "I hope this is a dream". Other times I have noticed when I was dreaming and knowing it was a dream, and that dreams were subjective, I acted much like a god does and changed my environment, flew around, played music and explored dreamscape etc. Yet the concept that I am dreaming in this present state affords no subjective influence, while in a dream to change my belief about my environment changes my environment, this does not occur in a waking state.
If two dream characters see the same thing does that make the dream reality objective? no.
By definition no, because they are in a dream which is by definition not-real, however that only exists in contrast to what is real. However a key part of objective reality is that it is observable by all observers, hence if you were subject to gravity, but found someone who was not, then gravity would not be objective. If your emotion could change gravitation, then it would not be objective, however all evidence points to gravity being objective.
The double slit experiment is objective because A, it is consistent when observed by more than one person and B, it is consistent regardless of the opinion or emotion of the observer.
Moreover though wave/particle duality just implies that a particle is a set of criteria that when met is defined as a particle, this is another topic but does not imply subjective reality.
We can be the observer and the observation at the same time and reality can still be objective as that A it does not change with regard to emotion or belief and B it is perceived by all, our opinions may vary, our concepts and beliefs may vary, but we all stick to the ground, we all bleed and breath and are born and die. So the issue of the observer being observation is not am issue of objective reality. Likewise it can only be a dream if we contrast it to what is not dream, if we have a concept of dream we imply that objective reality exists.
I can totally agree that the distinction between particle and wave is akin to the distinction between the observed and the observer, it has to do with where we perceive boundaries and the scales we look at. But this is objectively true, it is observable and consistent.
Objective reality is observable and consistent, we cannot even have a concept of subjective, of dream, of 'unreal' without it.
If we go to the teachings of say, certain eastern philosophies, perhaps we can observe that the concept there is not that things are or are not real, but that the truth is without property, making it neither subjective nor objective, for both are properties. That is not the subject of this thread per say, but it is invoked enough to address. Take Tao, it is without property, it has a name so we can refer to it, but it is not a thing, it is not existing nor non-existing, it has no property at all.
We can even note that objective and subjective are akin to Yin and Yang and that those would inevitably arise conceptually from wuji, which is from Tao. In this sense you cannot have objectivity without subjectivity or the reverse, both arise as distinct from their togetherness as reciprocals, and their togetherness arises from a lack of property that allows the development of property...
I believe in concepts of Veda among others, including Tao, but those support the objectivity of reality and the subjectivity of observation and their interaction for me, arising from a non-state.
