The physical sciences—physics, chemistry, biology—tell us a great deal about what our world is like. In addition, they tell us a great deal about what we are like. They tell us what our bodies are made of, the chemical reactions necessary for life, how our ears extract location information from sound waves, the evolutionary account of how various bits of us are as they are, what causes our bodies to move through the physical environment as they do, and so on. We can think of the true, complete physical account of us as an aggregation of all there is to say about us that can be constructed from the materials to be found in the various physical sciences. This account tells the story of us as revealed by the physical sciences.
