ABSTRACT
The thesis of this chapter can be stated succinctly, simply be replacing the “as” in its title by “is a”: The Scientist is a problem solver. If the thesis is true, then we can dispense with a theory of scientific discovery—the processes of discovery are just applications of the processes of problem solving. However, because the thesis is not obvious to everyone, and because the topic of scientific discovery has interest in its own right, perhaps it is worthwhile to say a little more about it.
