Well, this is one of those questions that you have to be in the right mood for. There are those to whom seeking an answer is the source of their career. Scientific researchers and clerics are amongst those who, like many of the philosophers, are wondering what the world is really made of – quite literally. Not only that, but ‘how do we know what is true and real’ and what is illusion?People who picked up this book who are not interested in this question may just skip it and go to the next chapter. A lot of the people who bought this book, actually like this question,even though it may seem strange if, say, you were just picking out drapes for the living room and suddenly ‘there it is, a question about the nature of reality’ and do the drapes go to just below the window sill or all the way down to the floor and will they match the sofa?Maybe you really think that way.OK, well, to start, on a daily basis, it certainly seems as if there is a lot which we take to be the truth. The sky is real, the kitchen is real; the need to buy toilet paper when one runs out is also real. At the same time, there is a lot in the world that doesn’t seem to even be real.Silicon breasts are not real in the same sense as natural ones. Lies are real too, but also not the way telling the truth is somehow real in a different way or more real, or real on more levels.We have our senses and our minds.
