Consciousness has long stood as one of the most enigmatic elements of human existence. Its very nature presents unique challenges to scientists and philosophers alike. Through the examination of various theories and thought experiments, from panpsychism to dualism, the quest to measure and understand consciousness continues to be a critical and daunting task.
Consciousness and Its Nature
Consciousness is often described as the state of being aware of and able to think about oneself and the environment. However, this definition oversimplifies a concept that involves subjective experience, awareness, and the feeling of what it is like to be someone or something.

“Consciousness essentially involves qualities if you think about the smell of coffee or the taste of mint or the deep red you experience as you watch a sunset” [01:08:03].
The Problem with Current Scientific Approaches
Current scientific methods struggle with the challenge of consciousness due to its qualitative nature. Unlike observable phenomena in physics or chemistry, consciousness involves subjective experiences that are not directly measurable.
Philip Goff, a philosopher and panpsychist, argues that consciousness is a fundamental aspect of the universe. He challenges the dominant scientific view that relies solely on quantitative descriptions.
Philip Goff's Perspective
Goff contends that “consciousness is the ultimate nature of matter” and thus must be accounted for within our understanding of the physical world [00:01:03].
Theories of Consciousness
Panpsychism
Panpsychism posits that consciousness is a fundamental and ubiquitous feature of the physical world. This perspective suggests that even the fundamental building blocks of reality, such as particles and fields, have simple forms of experience.
“The typical commitment of the panpsychist is that the fundamental building blocks of reality…have incredibly simple forms of experience” [01:08:14].
Dualism and Materialism
Dualism, contrasting with panpsychism, suggests that consciousness and the physical body operate independently. Meanwhile, materialism maintains that consciousness can be fully explained by physical processes. However, both theories come with limitations that fail to fully encompass the experiential qualities of consciousness.
Measurement Challenges
The quest to measure consciousness involves unraveling the relationship between brain activity and experience. Researchers hunt for the neural correlates of consciousness, aiming to find physical processes that align with conscious experience.
“We’re trying to account for these subjective qualities and you postulate a mechanism that might explain behavior but it doesn’t explain the redness of a red experience” [01:27:17].
Integrated Information Theory (IIT)
One leading theoretical approach in neuroscience is the Integrated Information Theory, which attempts to quantify consciousness by the degree of integrated information within a system. However, even this theory faces challenges in capturing the qualitative nature of consciousness.
Conclusion
The task of understanding consciousness demands a multifaceted approach, combining experimental data with philosophical inquiry. As Goff and others advocate, an evolution in scientific methods might be necessary—one that acknowledges consciousness as an intrinsic element rather than an emergent property.
Ultimately, as science and philosophy venture deeper into this mystery, the promise lies in bridging the tangible and the intangible, offering a more profound comprehension of what it means to be conscious.
