Patricia S. Grigson

This book was written by my thesis mentor, the late Charles F. Flaherty. He was the expert in the study of the relative aspects of reward, and the work described in this seminal book provided the foundation for my current area of research on substance abuse and addiction. Charles Flaherty taught that all is knowable, basic science is critical preparation for an unknown future, and a theory need not be correct, it only needs to be testable.
