No. I am saying we cannot show a objective reality. One after all cannot disprove existence. Thus if you or I am going to make a claim of existence we must show proof through the observations of the subject.
In this case where is the imaginary object when speaking of objectivity. It is in the mind. A subject may not observe the imaginary object. Nothing to observe for the subject, but effects and affects. Not the object, thus the object is not logical nor reasonable. It is irrational. This miss identification of objectivity is what is being used to confuse the subjects.
The subjects attempt to use the rational mind breaks the logic and reason neural pathways of the brain, because there is no measurement that a subject can be using to describe the verb action of being for the imaginary object called objectivity. Making Objectivity Imaginary. Use of the irrational mind is indicated by the state of being immeasurable. This is hard to comprehend because we don't have the right language to discuss this.
Perhaps we can create the right language. All person places or things are verbs. This is because no object in the universe is actually at rest. Thus noun's are a sub category of verbs. When we say something is at rest we are not describing a true condition, but expressing a apparent condition. A perception of the mind that actually in fact doesn't exist. So because it doens't exist in the universe the condition is a irrational projection of the mind. It doens't have anything to do with logic and reason.
Does this Help?
RE: Ontology what is the observer observing? The action of being a measurment in reality!
