To quote myself, “I believe one of the great questions of our time is one pondered by Plato: ‘what is reality?’” In all honesty, I have delved, but never settled for a definite answer. In a contradiction, I am Aristotelian in believing in change, even when I want to refute it.
I think one has to adopt a position of one of two ways: ‘the world we know is real’, ‘the world we know is an image, replication or interpretation’. As you can see, I begin to get carried away with the middle-specifics of questions. Is the world real? Well, that depends on whether you mean this world, or a world. For instance, our world may be a holographic illusion, but there has to be a first-level world beyond that to project our world. I shall, however, stick with the questions as they are, and focus on a way to understand what reality is.
One might say that, empirically, there can be no doubt. I have a very solid, very real laptop beneath my fingers on which I am typing with very real fingers. However, I cannot believe this myself entirely. I cannot consider that what I am experiencing is the true reality, that is: it is not just a dream inside my head. Everyone dreams. And these dreams feel very real when we are in them. Some are more so than others; some can cause confusion, such as those where you perform acts of awake situations whilst in dream-state, but then wake to find you have not, say, got dressed yet, even though you fully recall doing so.
See, reality is much more versatile and tricky than that.
It may also come into light that one’s view of reality changes depending on what mood or situation one is in. The ‘I must be dreaming!’ is an exclamation that doubts the truth of situations we can clearly see with our eyes. Whilst emotion must play a great part in the interpretation of whether our world is real, it does not actually argue inthe case itself.
Using emotion once more, I come back to the ‘projection’ case, considering that it is possible our world could change to accommodate our emotions. If, indeed, we are only the second (or third or fourth) level occupants, it is highly likely that we may be being controlled or cared for from above.
Do I personally believe this? I’m not sure. Certainly, the world is more complex that can be empirically discovered, in the cases of thought, intelligence and other such logical structures (I don’t quite think that the science of the psyche: Psychology or the Cognitive model can quite explain the depth of the metaphysical), but there is even more to it than that. The world is an organism in itself of great potentiality and actuality – and we can’t deny that it could all be a trick of the mind. Whilst I have concerns about the concept of our being second-level individuals, I am not sure that the physical reality stands as it is: there is little proof in the illusion of reality, but the fact that we can go beyond it in our minds stands to raise the issue quite nicely for me.
Reality is real – until proven false.
 And there are many hypotheses on the internet that can be sought out. For instance, that of Oxford philosopher, Bostrum, that our universe is a second-level projection.
