As odd as it sounds, I do not believe there is any accurate way of knowing whether our senses are an accurate presentation of the world. This is because I think that everyone's minds have a little "glitch" and therefore somehow has an impact on the way we see/perscieve the world.

You may see something that is not there, it could have been just a leaf buzzing by and not a super-intellegent microbug sent out by an underground organisation to destroy all of you shoes. Your brain is wired to see, do, feel, taste and hear to a certain extent but when we are constrating we miss things because our minds are more concerned with what we are giving all of our attention to. When we do see something, a leaf buzzing by for example, our minds make an assumtion and try to "guess" what we just saw. Of course we cannot rely on our senses 100% otherwise a large percentage of Earth's population would believe that 'The Sound of Music' is being preformed live under their beds and not think it is just their imagination. Scary stuff, eh?
