Why did people oppose James simpsons ideas?

People opposed James Simpson's ideas, particularly his advocacy for anesthesia in surgery, due to prevailing medical beliefs and practices of the time. Many physicians were skeptical of the safety and efficacy of anesthesia, fearing it would complicate procedures or lead to unforeseen complications. Additionally, some opponents believed that pain was a necessary aspect of surgery, arguing that it was a natural part of the healing process and that anesthetics could interfere with a surgeon's ability to gauge a patient's condition. Religious and moral objections also played a role, as some believed that alleviating pain went against the idea of suffering as a part of the human experience.
