The Enduring Fascination with the Theory of Four Humours

09 Apr 2024

Have you ever wondered why some people seem to radiate sunshine while others are constantly caught in a storm cloud? For centuries, people have sought to categorize and explain personality types, looking for patterns that could offer insights into human behavior. One of the most enduring of these systems, though now long debunked scientifically, is the theory of four humours.

Imagine a world where your temperament, your very essence, was believed to be governed by the balance of four fluids within your body: blood, phlegm, yellow bile, and black bile. This, in essence, is the theory of four humours, a concept that originated in ancient Greece and held sway in Western medicine for over 2,000 years. While we now understand that personality is far more complex than this, exploring the four humours offers a fascinating glimpse into the history of medicine and our understanding of ourselves.

The theory of four humours is rooted in the teachings of Hippocrates, often hailed as the father of medicine. He believed that these four humours corresponded to the four elements of nature – air, water, fire, and earth – and that maintaining a balance between them was crucial for good health. This idea was further developed by the Roman physician Galen, whose writings became highly influential throughout the Middle Ages and Renaissance.

Each humour was associated with specific personality traits. A sanguine person, with an abundance of blood, was thought to be cheerful, optimistic, and sociable. An excess of phlegm, on the other hand, resulted in a phlegmatic personality – calm, passive, and unemotional. Yellow bile, linked to fire, produced choleric individuals: passionate, ambitious, and quick to anger. Finally, an excess of black bile was believed to cause melancholy, characterized by introspection, sadness, and creativity.

While the theory of four humours has long been discredited as a medical model, its legacy continues to resonate in language and literature. We still use terms like "sanguine" and "melancholy" to describe personality types, and the vivid imagery of Shakespearean characters influenced by their humoral dispositions continues to captivate audiences. The theory serves as a reminder of humanity's enduring quest to understand the complexities of human behavior and the indelible mark these ancient ideas have left on our cultural understanding of personality.
