We are being "deceived" by our senses all the time. We dont see the world as it actually is, but only as our senses "tell" us how it is. For example, there is not what we call "white light". The white is in fact all colors superposed. If we could see the world as it actually is, instead white we would see all colors at the same time. But, our senses and brain interfere, and creates the "white", which seems a pure color. But it is not. Its only a "simplification".
And the same goes for all our senses. What we call the "outside world" which is percieved by our senses is just a representation, a description of the actual world. Very much the white is only a representation of "all the colors together".

But now im left wondering... What would your teacher think if you wrote things like that in your test?
