  Let us look in depth at a discussion of these issues occurring in Science and Mechanics in a chapter entitled “The Economy of Science.” The section occurs toward the end of the book, and begins: “It is the object of science to replace, or save experiences, by the reproduction and anticipation of facts in thought. Memory is handier than experience, and often answers the same purpose.” [SM: 577] The economical role of science is to allow us to understand and react to nature prior to experience; just as a newborn chicken knows what to do as soon as it is hatched due to its accumulated memory (it doesn’t need to learn on its own as the learning has already been done by its ancestors), so we now learn from science how to anticipate the world. Our memory encompasses more and more of the world, thus allowing better and better orientation.
