If we look through a piece of glass, irregularities and impurities may distort and discolor the impression of what we see. If we regard something through a convex lens, it appears to be upside down. But if we place a concave lens in front of the convex lens, we correct the distortion in the convex lens and things no longer appear topsy-turvy. Each one of us regards the world through his own lens, his own glasses. The effect of those glasses is that, even though we may be looking at the same thing, not all of us actually see the same thing. The lenses are ground by each individual’s upbringing, disposition and other factors.
This book is neither art nor science — even though it borrows ingredients from both. It is more by way of being an extra piece of glass through which we can regard a part of life. One can slip it in between one’s own glasses and the window.
It is a piece of glass we have found and polished up a bit. We have looked through it and thought the world looked a bit more human. Perhaps some will think the same as we do."
