Where debating everything under the sun is only the beginning

So, does any objective exist?

The world we see, being seen by the eye, is the object. The eye which sees it is the subject. But the eye, when perceived by the mind is the object and the mind which sees it is the subject. The mind with its thoughts perceived by the Self is the object and the Self is the subject. The Self cannot be the object, not being perceived by anything else.

The forms perceived are various, blue and yellow, gross and subtle, tall and short, and so on; but the eye that sees them remains one and the same. Similarly, the varying qualities of the eye, such as blindness, dullness and keenness and of the ears and other organs, are perceived by the mind singly. So, too, the various characteristics of the mind, such as desire, determination, doubt, faith, want of faith, courage, want of courage, fear, shyness, discrimination, good and bad, are all perceived by the Self singly. This Self neither rises nor sets, neither increases nor decays. It shines of its own luminosity. It illumines everything else without the need for aid from other sources.

Your question was about ontology of the object.

The objective world has relative existence.
