Different Ways to Understand Disease: A Journey Through Greek, Modern, and Chinese Medical Theories
Throughout history, diverse cultures have approached the understanding and treatment of disease in various ways. In ancient Greece, figures such as Asclepius and Hygieia epitomised a blend of healing practices that emphasised both curative and preventive medicine. Their philosophies continue to resonate in contemporary discussions surrounding health, especially when considered alongside the scientific advancements made by pioneers like Louis Pasteur, Claude Bernard, and Antoine Béchamp. Additionally, traditional Chinese medicine (TCM) offers a unique perspective that complements these ancient and modern theories. By examining these different approaches, we can cultivate a more nuanced understanding of health and disease, transcending singular narratives and recognising the value of integrating diverse medical traditions.
The Role of Asclepius and Hygieia in Ancient Greek Medicine
In ancient Greece, two key figures embodied the dual approach to understanding health and disease: Asclepius and Hygieia. Both were gods associated with healing, but they symbolised very different aspects of medicine.
Asclepius: The God of Healing and Curative Medicine
Asclepius was the god of medicine, worshipped as the divine healer. His temples, known as Asclepieia, were centres of healing where the sick would come to be cured. People believed Asclepius could cure illness through direct intervention, sometimes even raising the dead in myth. In these temples, patients would undergo rituals like incubation, sleeping in the sacred temple with the hope that the god would appear in their dreams and reveal a cure. Priests, often acting as physicians, interpreted these dreams and prescribed treatments ranging from herbal remedies to surgery.
The idea behind Asclepius is simple: if you are sick, you need treatment. This is a very curative approach, focusing on resolving a problem once it has occurred. It mirrors what we see today in much of Western medicine, where interventions such as medications, surgeries, or therapies are used to treat specific diseases.
The symbol of Asclepius, a staff entwined with a serpent, has remained a global emblem of medicine. This approach is effective, particularly in acute situations, when immediate action is needed to cure an illness or manage a serious health problem.
Hygieia: The Goddess of Preventive Health
In contrast, Asclepius’s daughter, Hygieia, symbolised preventive health. Her role was not to cure disease, but to maintain health and prevent illness. Cleanliness, a balanced lifestyle, and attention to personal well-being were the keys to staying healthy. This is where the modern word "hygiene" comes from, as Hygieia represented practices that protected individuals from becoming sick in the first place.
This preventive approach is not just about reacting to illness but about ensuring that the body remains in a state of balance so that disease never takes hold. In this way, Hygieia represents the other side of the medical coin, reminding us that health is not just about treating illness but also about making sure our bodies and minds remain in optimal condition.
Modern Medicine: Pasteur’s Germ Theory and Bernard’s Internal Balance
Fast forward to the 19th century, and we see a similar dichotomy in the theories of disease developed by Louis Pasteur and Claude Bernard. These two figures were crucial in shaping modern medicine, yet their ideas about the causes of disease were, in some ways, reflective of the ancient Asclepian and Hygieian traditions.
Louis Pasteur and the Germ Theory of Disease
Pasteur is famous for developing the Germ Theory, which revolutionised our understanding of disease. He demonstrated that many diseases are caused by microorganisms, such as bacteria and viruses, which invade the body from the outside. This breakthrough led to the development of vaccines, antiseptics, and antibiotics, all aimed at attacking these harmful invaders.
In this model, disease is caused by an external agent that must be fought with targeted interventions. Just as the Greeks looked to Asclepius to cure sickness after it appeared, Pasteur’s Germ Theory focuses on identifying the pathogen and treating it—whether through vaccination, sterilisation, or medications. It’s a clear parallel to curative medicine, where the focus is on solving a problem after it arises.
Claude Bernard and the Internal Environment
At the same time, Claude Bernard and Antoine Béchamp presented a contrasting view. They emphasised the importance of the body’s internal environment, or "milieu intérieur", in determining whether or not disease would take hold. According to Bernard, it wasn’t enough to focus on external germs or pathogens; what mattered just as much, if not more, was the balance of the body’s internal systems.
Béchamp’s Cellular Theory similarly argued that microorganisms could only cause disease if the body’s internal environment was unhealthy or out of balance. He believed that maintaining the health of the “terrain” (the body’s internal state) was key to preventing illness. This idea has a clear parallel with Hygieia’s approach in ancient Greek medicine: if you keep your body in balance, it is better able to resist disease.
In this way, Bernard and Béchamp’s theories remind us that preventive health and internal balance are as important as treating the symptoms of disease after they appear.
Chinese Medicine: Balance and Harmony in Health
The ancient Chinese also developed a sophisticated understanding of health and disease, and their approach similarly blends the curative and preventive aspects of medicine. Traditional Chinese Medicine (TCM) is rooted in the philosophy of balance, particularly the balance between Yin and Yang, and the smooth flow of Qi (vital energy) through the body.
Yin-Yang and Qi: The Importance of Balance
In TCM, health is seen as a state of harmony between Yin (coolness, stillness, moisture) and Yang (heat, activity, dryness). The smooth, balanced flow of Qi through the body’s meridians is essential to maintaining this harmony. Disease arises when there is an imbalance in these forces or a blockage in the flow of Qi.
This view aligns closely with the preventive health focus of Hygieia and Bernard. If the body is kept in balance, disease is less likely to take hold. In TCM, practices such as acupuncture, herbal medicine, and dietary regulation are used not just to treat illness but to keep the body in a state of harmony, preventing disease from occurring in the first place.
The Six Pernicious Influences: External Causes of Disease
At the same time, TCM recognises that external factors, such as wind, cold, heat, and dampness, can invade the body and cause illness. These are known as the Six Pernicious Influences. When these external pathogens attack the body, they disrupt its internal balance, leading to disease.
The treatment for such illnesses often involves expelling the pernicious influence and restoring balance through acupuncture, herbal remedies, or other interventions. This focus on external causes of disease resembles Pasteur’s Germ Theory and the curative medicine approach seen in Asclepius’ tradition. Once disease has taken hold, active intervention is needed to restore health.
A Holistic Approach: Blending Curative and Preventive Medicine
As we can see, different cultures and thinkers have developed distinct ways of understanding disease. Whether it’s the curative interventions of Asclepius and Pasteur or the preventive focus of Hygieia and Bernard, there is no single “right” way to approach health. In fact, these approaches are complementary.
When illness arises, we need the curative tools of medicine to restore health. Antibiotics, surgeries, and treatments are indispensable when faced with acute illness or infection. But preventive health is just as important. By maintaining balance through healthy living, diet, and self-care, we can strengthen our bodies and avoid disease before it strikes.
Chinese medicine, with its focus on both internal balance and external pathogens, provides a holistic model for blending these approaches. In modern healthcare, we can see how preventive practices such as vaccinations, hygiene, and nutrition coexist with life-saving treatments like medications and surgeries.
Conclusion: Neither Approach Is Better—Both Are Necessary
In the end, there is no single “true” or “better” way to understand disease. The reality is that both curative and preventive approaches are necessary depending on the circumstances. Sometimes, we need to fight an infection with antibiotics; other times, the best medicine is prevention through a balanced diet and healthy habits.
Whether it’s the wisdom of ancient Greece, the insights of modern science, or the holistic philosophy of Chinese medicine, these different theories remind us that health is a complex and multifaceted issue. The best path to well-being is likely a combination of approaches, where we maintain balance and harmony while also being prepared to cure illness when it arises.
Ultimately, true health involves both understanding external threats and nurturing our internal balance, drawing on the insights from different cultures and traditions. By recognising that no single theory has all the answers, we open ourselves up to a more complete and effective understanding of health and disease.
