What makes chemistry unique? And how does this uniqueness reflect on chemistry’s unique concerns with ethics? As Roald Hoffmann (1995) argues, it is because chemistry is in the “tense middle,” occupying a space between several pairs of extremes. Perhaps most important, chemistry has always inhabited a frontier between science and technology, the pure and the applied, the theoretical and the practical (Bensaude-Vincent and Simon 2008). Unlike the other natural sciences, chemistry traces its origins both to philosophy and the craft tradition. Chemists are discoverers of knowledge and creators of new substances. The objects of study in chemistry, molecules and the macroscopic systems made up of molecules, are intermediate between the very small, the elementary particles, and the very large, the cosmos. Chemical systems are the right size to affect humans directly, for better or worse. They are the building blocks of biological organisms, they are the substances we eat and drink, they are the drugs that have improved human health dramatically over the past century, they comprise the materials we use to construct the products we use daily, but they are also the environmental pollutants that can plague our world. Chemicals can also be used as weapons. Being in the middle means that chemists face a unique set of ethical issues that I try to explicate in this chapter. These issues derive, in part, from the nature of chemistry as a science, a science that does not fit the neat picture drawn in the first chapter of textbooks. They also derive from the fact that ethics is an inquiry into right human conduct: What is a good life? Chemistry has perhaps contributed more to the betterment of human life than any other science, but at the same time has also contributed significantly to the deterioration of the environment. As explained in Chapter 3, much of chemistry is conducted in Pasteur’s quadrant, where both the search for fundamental knowledge and considerations of use are important. Chemical synthesis is perhaps the central activity of chemistry.
