The only reality we can ever truly know is that of our perceptions, our own consciousness, while that consciousness, and thus our entire reality, is made of nothing but signs and symbols. Nothing but language.
Even God requires language before conceiving the Universe. See Genesis: “In the beginning was the Word.

Reality, at first glance, is a simple thing: the television speaking to you now is real. Your body sunk into that chair in the approach to midnight, a clock ticking at the threshold of awareness. All the endless detail of a solid and material world surrounding you. These things exist. They can be measured with a yardstick, a voltammeter, a weighing scale. These things are real.

What is meant by “reality”? It would seem to be something very erratic, very undependable — now to be found in a dusty road, now in a scrap of newspaper in the street, now a daffodil in the sun. It lights up a group in a room and stamps some casual saying. It overwhelms one walking home beneath the stars and makes the silent world more real than the world of speech — and then there it is again in an omnibus in the uproar of Piccadilly. Sometimes, too, it seems to dwell in shapes too far away for us to discern what their nature is. But whatever it touches, it fixes and makes permanent. That is what remains over when the skin of the day has been cast into the hedge; that is what is left of past time and of our loves and hates.

Reality can neither be proved nor disproved. Within the mind you cannot, beyond the mind you need not. In the real, the question 'what is real?' does not arise. (...)

Reality must be always real. It is not with forms and names. That which underlies these is the reality. It underlies limitations, being itself limitless. It is not bound. It underlies unrealities, itself being real. Reality is that which is. It is as it is. It transcends speech. It is beyond the expressions `existence, non-existence', etc.

you want to know what reality is, you must look directly at it and see for yourself. But this needs a certain kind of concentration, because reality is not symbols, it is not words and thoughts, it is not reflections and fantasies. Therefore to see it clearly, your mind must be free from wandering words and from the floating fantasies of

Reality contains not only evidence, but also the means (such as our minds, and our artefacts) of understanding it. There are mathematical symbols in physical reality. The fact that it is we who put them there does not make them any less physical.

The greatest thing about provable reality is that by definition reality is shared. Every argument is really an agreement — an agreement that there is a reality that can be shared, judged, and discussed. To argue over whether the speed of light is constant or Batman could beat up the Lone Ranger is to share the parameters. God is solipsistic; reality is shared.

It will be enough, for our purposes, to define 'reality' as a quality appertaining to phenomena that we recognize as having a being independent of our own volition (we cannot 'wish them away'), and to define 'knowledge' as the certainty that phenomena are real and that they possess specific characteristics.

In order to express our sense of reality, we must use some kind of symbol: words or notes or shades of paint or television pictures or sculpted forms. None of those symbols or images can ever completely satisfy us because they can never be any more than what they are — a fragment of a reflection of what we feel reality to be.

Reality is reality. It transcends every concept. There is no concept which can adequately describe it, not even the concept of interdependence.

...truth is reality

Human beings do not live in the objective world alone, nor alone in the world of social activity as ordinarily understood, but are very much at the mercy of the particular language which has become the medium of expression for their society. It is quite an illusion to imagine that one adjusts to reality essentially without the use of language and that language is merely an incidental means of solving specific problems of communication or reflection. The fact of the matter is that the "real world" is to a large extent unconsciously built upon the language habits of the group. No two languages are ever sufficiently similar to be considered as representing the same social reality. The worlds in which different societies live are distinct worlds, not merely the same world with different labels attached … We see and hear and otherwise experience very largely as we do because the language habits of our community predispose certain choices of interpretation.
