- Explain the evolutionary account of change in science.
- Why does Leahey say that Kuhn's and the evolutionists' accounts may not be naturalistic enough?

- Does it matter whether or not psychology is considered to be a science? Why?
2. Arguments from Imperfection
- Describe some of psychology's "imperfections" that threaten its status as a science.
3. Arguments from Impossibility
a. You Can't Eliminate the Mind: The Failure of Behaviorism
- How did the desire for psychology to be a science lead to behaviorism?
- Leahey explains behaviorism's failure by saying "psychology cannot be limited only to publicly observable behavior." Why not?

2. Mind in Religion
- What are the two reasons why "psychologists have underestimated the influence of religious ideas of the soul...on conceptions of mind and self?"
- "Although there are differences in detail, religions around the world have a remarkably concordant picture of the mind, positing the existence of two immaterial sould for two distinct reasons." What are those reasons?
