What did Vesalius think caused illness?

Answer 1

Andreas Vesalius believed that illness was primarily caused by anatomical and physiological imbalances within the body rather than by imbalances of the four humors, which was the prevailing theory at the time. He emphasized the importance of direct observation and dissection to understand the human body, leading to a more accurate understanding of disease. Vesalius's work laid the foundation for modern anatomy and shifted the focus toward the physical structure of the body as a key factor in health and illness.
