Sensory perceptions can be fake and the universe can be a fabrication. However a more important consideration is this. The only criterion you can every utitilize to judge the nature of the fabrication is sensory perception itself. Without sensory perceptions the "real" universe might as well not exist. If you never experience a "real" reality it simply does not exist for you. You will never "experience" the real universe - you will always merely experience your perception of it. Is it possible that perception is all that exists and that there is no real universe? Remember any argument you use to refute this will be based in your logical, emotional or inferenceial perception.

Classic philosophy often hints that perception is a shadow of reality. Is is possible that reality is a shadow of perception?

So, what you are asking is whether a tree falling in the forest makes a sound if there are no ears to hear it? :rolleyes:

Or maybe... What there are many things smelling good if there aren´t any noses to know it?!
We have our perceptions to fell what this World can offer for us.

No actually the question is different than that - if you hear a tree falling in the forest why do you assume there is a tree there at all. Take it one step forward and realize that the only reality you will ever know is in your head. There is truly no such thing as an external reality - only the guestimates you have on future sensory perceptions. You will never experience reality only the image of it in your head.

I never thought of that..... And the scary thing is, I understood every word of what you said.....

sound travels anywhere as long as you are not in space

sensory perception are used to percieve the real world and the universe. so how do we know whether the universe is real? this is how.....
though we have perceptors, we have freewill also. we have eyes to see, the brain interprets whatever we see and creates images etc. but the most important point is that we can CHOOSE what we see. we have the choice. we can choose what we hear.dont forget that.

The interpretation itself is just sophistaicated sensory percetion - nothing more. Choice is an illusion - you feel ("sense") that you have choice but you do not - whether you think in a classical sense or a quantum sense the underlying physics in thought is never a choice. The concept of free will is an amusing one, but fortunately or unfortunately misplaced and incorrect.

that was an interesting post i have also thought of extistence as that but you Carpediem have put it so well very cool

even i believe that perfect freewill is a utopian concept, but we do have freewill to quite some extent. if u would like more info on the subject, read up on MODERN PROCESS PHILOSOPHERS- A.N Whitehead and Charles Hartshorne

One's perception of reality is based solely on one's interpretation and prioritization of sensory input.

Once blinded, there is still light.
Once deafened, there is still sound.

The world of the ant is a very different place from that of the eagle.....and neither would be recognizable to the bacterium, were it to attempt to process the sensory input provided by either.....yet each can influence the reality of the other.

It is not our perception of reality which is important, but our ability to influence the reality of those around us.
