What Do Historians Think?

🔎 What Do Historians Think?

Interpretation 1 — Modern medicine's technological and pharmaceutical approach is the greatest achievement in human history: Historians and commentators in the tradition of Roy Porter celebrate the 20th and 21st century medical revolution as humanity's greatest achievement. Life expectancy in Britain rose from 47 years (1900) to 81 years (2000). Smallpox has been eradicated. Childhood diseases that once killed millions are now preventable by vaccination. Organ transplants, cancer chemotherapy, and joint replacement surgery save and transform lives daily. The discovery of DNA's structure in 1953 has unlocked the possibility of targeting disease at the genetic level — personalised medicine, gene therapy, and genetic screening represent a new frontier that makes previous medical advances look modest by comparison. No other development in human history has so dramatically reduced suffering and extended life.

Interpretation 2 — Modern medicine's emphasis on technology and pharmaceuticals is creating unsustainable problems, including antibiotic resistance: Critical historians and public health researchers, including Mark Honigsbaum and many epidemiologists, argue that 20th-century medicine's extraordinary successes have come with serious costs that threaten to undermine them. The overuse of antibiotics — in medicine and, crucially, in animal farming — has driven the evolution of drug-resistant bacteria. MRSA, drug-resistant tuberculosis, and drug-resistant gonorrhoea are already significant clinical problems. The WHO predicts that by 2050, antibiotic resistance could cause 10 million deaths annually — more than cancer currently kills. Additionally, the pharmaceutical model has been largely ineffective against lifestyle diseases, mental health conditions, and dementia — which are the defining health challenges of the 21st century. The tools that defeated infectious disease may not be the right tools for this new landscape.

Why do they disagree? Both perspectives draw on real evidence — the extraordinary achievements of 20th-century medicine are undeniable, and so are the emerging threats. The disagreement reflects different time horizons (past achievements versus future challenges) and different frameworks (what medicine has done versus what it faces). For AQA's thematic study, the most valuable insight is that medicine involves ongoing cycles of new problems emerging as old ones are solved — the pattern of continuity and change that runs throughout the entire course.
