The Subjective Character of Existence

The hallmark of the objective (the non-subjective) is that it can be studied with science--it can be independently verified by anyone who is in the right place, at the right time, with the right means of making a measurement.   But in order for something to be independently verified, it must be possible to describe what is being verified, so that the different experimenters can meaningfully agree.

Therefore, the essential nature of the objective is that it can be described.

But reality cannot be brought into existence solely through a description of reality.   Thus the essential quality of existence is beyond description, and is therefore subjective rather than objective.
