Book excerpt: Gain a better understanding of human behavior by exploring thought experiments in Shakespearean plays and the historical roots of experimental psychology within early modern literature. This book combines scientific psychology with English literature to discuss thought experiments in selected Shakespeare plays and examine the central role of thought experiments in the natural sciences. Thought experiments are essential for progress in scientific research. Indeed, Albert Einstein and a number of other leading scientists relied almost exclusively on thought experiments. Thought experiments also play a pivotal role in English literature, particularly in Shakespeare plays. By focussing on thought experiments and experimental psychology's place within early modern English literature, the volume establishes a more wholistic approach to understanding human behavior.
