Science, appearances, and representation ... Threading them together is what this book is essentially about. The author subscribes to the empiricist structuralist school of thought with respect to science. In a nutshell, what he believes is that rather than laying bare the objective workings of nature, science can only be successful at mapping appearances within a coherent system of theories and empirical predictions. It has to make it all hang together. In this sense, Van Fraassen falls into the same philosophical camp as Quine and Duhem who too think that a belief is believed in so far as it imparts cohesion to a system of preexisting beliefs or scientific statements. If you believe this trio, what science is is like the framework whereby you can properly interpret "You are here" on a mall map. "You are here" represents the systematic locus of your preexisting empirical beliefs and theories, while the rest of the map is what you confront anew and try to make sense of. In other words, science is a structural representation of, not necessarily the objective nature of nature, but of how you represent it all to yourself. This book is thus another arrow in the quiver of a philosophical skeptic. It is a book with good content, but the writing was a bit wordy and repetitious.
