Your opinion. There are many others. From the Gemini summary (which also summarizes a lot of Zoom conferences I’ve been in with people who study these matters professionally), there is nothing like a 400-year Western scientific tradition of studying consciousness. More like a 400-year tradition of excluding consciousness from study. Re-considering the Cartesian dualistic move and exploring what other cultural traditions had to say about these matters is one of the many available current options to serious students of these matters.
Gemini summary:
The history of Western science’s relationship with consciousness is a dramatic, centuries-long story of rejection, avoidance, and ultimate obsession. For a long time, consciousness was considered “the C-word” in polite scientific discourse—a messy, subjective topic best left to theologians and poets.
To trace its history is to watch Western science move from absolute separation (the soul vs. the body) to extreme denial (the brain as just a machine), and finally to a modern, multi-disciplinary scramble to solve what is now called “The Hard Problem.”
1. The Great Split: Descartes and the 17th Century
Before the Scientific Revolution, the study of the mind was entirely wrapped up in theological concepts of the immortal soul.
In the 1600s, René Descartes attempted to pave a way forward for the new mechanistic science without angering the Church. He proposed Substance Dualism, dividing the universe into two entirely different substances:
-
Res extensa** (Extended things):** Matter, the physical world, and the human body. This realm was purely mechanical, predictable, and could be studied by science.
-
Res cogitans** (Thinking things):** The immaterial mind, soul, and conscious experience. This realm was unquantifiable and belonged to God and philosophy.
By handing the physical body over to science and keeping consciousness in the realm of religion, Descartes allowed early physics, anatomy, and chemistry to flourish without having to worry about the subjective experience of the observer.
2. The Early Pioneers: The Late 19th Century
By the late 1800s, scientists began to wonder if the “thinking thing” could be studied using the tools of the laboratory. This era birthed experimental psychology.
-
Wilhelm Wundt (1879): Established the very first psychological laboratory in Germany. He used a method called introspection, where highly trained subjects would report their precise, immediate conscious experiences (colors, tones, feelings) when exposed to specific stimuli.
-
William James (1890): In his monumental work The Principles of Psychology, the American philosopher and psychologist famously coined the phrase “the stream of consciousness.” James argued that consciousness is not chopped up into bits, but flows like a river, constantly changing and adapting to help humans survive.
3. The Great Exile: Behaviorism and Materialism (1913–1960s)
Just as consciousness research was gaining traction, a massive scientific backlash occurred. A new generation of scientists argued that because subjective experience cannot be seen, measured, or verified by an independent third party, it has no place in objective science.
-
John B. Watson and B.F. Skinner (Behaviorism): Watson’s 1913 manifesto Psychology as the Behaviorist Views It completely redefined the field. Behaviorists argued that the human mind is a “black box.” You can measure the input (stimulus) and the output (behavior), but whatever happens inside (conscious thought) is scientifically irrelevant.
-
The Taboo: For nearly half a century, studying consciousness became a career-killer for mainstream Western scientists. It was dismissed as an unscientific illusion.

4. The Cognitive Revolution and Neuroimaging (1960s–1980s)
By the mid-20th century, the behaviorist straightjacket began to tear. The invention of the digital computer gave scientists a new metaphor for the mind: information processing.
The Cognitive Revolution proved that you could scientifically study internal mental states (like memory, attention, and language production) by treating the brain like a biological computer.
Furthermore, the late 20th century brought revolutionary medical technologies:
- PET Scans and fMRIs: For the first time, scientists didn’t have to guess what was happening inside the “black box.” They could watch the living human brain light up in real-time as a person thought, dreamed, or perceived.
5. The Modern Era: NCC and “The Hard Problem” (1990s–Present)
The true renaissance of consciousness studies exploded in the 1990s, catalyzed by two major milestones.
Francis Crick and Christof Koch (1990)
Francis Crick (co-discoverer of the DNA double helix) decided to use his massive scientific clout to make consciousness a legitimate field of study. Alongside neuroscientist Christof Koch, he launched the hunt for the Neural Correlates of Consciousness (NCC). The goal was purely empirical: find the exact specific brain states, neurons, and synchronized electrical firings that correspond to a specific conscious experience (like seeing the color red).
David Chalmers and “The Hard Problem” (1995)
While the hunt for the NCCs was booming, Australian philosopher David Chalmers threw a wrench into the gears. He divided the field into two categories:
-
The Easy Problems: Figuring out how the brain integrates information, focuses attention, or controls behavior. These are “easy” because they can eventually be explained by mapping the brain’s biological wiring.
-
The Hard Problem: Why should all that biological wiring feel like anything from the inside? Why do we have a qualitative, subjective experience (called qualia) instead of just being blind, automated biological robots (or “zombies”)?
Where Science Stands Today
Today, Western scientific interest in consciousness is at an all-time high, fractured into competing, mind-bending theories that attempt to solve Chalmers’s Hard Problem:
-
Integrated Information Theory (IIT): Suggests that consciousness is a fundamental property of the universe (akin to mass or electrical charge) that emerges anywhere information is highly integrated.
-
Global Neuronal Workspace Theory (GNWT): Treats the brain like a theater; consciousness is whatever information is brought into the “spotlight” of the stage, broadcasting it to the rest of the unconscious brain.
-
Panpsychism / Idealism: A growing minority of scientists and philosophers are moving backward to move forward, questioning the materialist paradigm entirely and suggesting that consciousness might not be created by the brain at all, but is instead the fundamental fabric of reality itself.
