Irritability: A Physiological Analysis of the General Effect of Stimuli in Living Substance

"Irritability: A Physiological Analysis of the General Effect of Stimuli" by Max Verworn is a scientific book that examines how living things react to different triggers, such as light, heat, or chemicals. The author explores the history of the idea of irritability – basically, how living stuff responds to its surroundings – going back to thinkers from long ago. He wants to bring together different experiments and ideas to create a clear picture of how stimulation affects living organisms, viewing it as a core way to understand life itself. The book aims to show how important it is to study these reactions to truly get how life works. Verworn seeks to methodically investigate the effects of stimulation across various biological systems, building a solid base for the more detailed study found in proceeding chapters.
