Host: Dario Zanca
Guest: Pietro Perconti
Dario: This is my conversation with Professor Pietro Perconti, a scholar of the philosophy of mind at the University of Messina and co-founder of the International Center for Consciousness Studies. Our conversation today will explore the concept of consciousness in its many forms, including artificial consciousness. Ultimately, we aim to answer the fundamental question: What does it truly mean to be human?
Dario: Let’s start with the big question: What is consciousness? Some argue that it is merely an illusion, a construct of the human brain. Others believe that it is a fundamental property of the universe, present in all things—even inanimate objects like stones. Where do you stand on this?
Pietro: That is indeed a difficult question, but an essential one. Historically, consciousness has been considered an almost taboo topic in cognitive science. Many researchers, especially in Anglo-American traditions, dismissed it as something beyond scientific study. However, I believe consciousness is a legitimate subject of scientific inquiry.
One reason why it has been difficult to study is that consciousness seems to contradict some of the fundamental principles of Western scientific frameworks. Unlike other phenomena, such as memory or tectonic plates, consciousness inspires an unshakable personal confidence in its existence. We intuitively believe that our own consciousness is real in a way that is distinct from other scientific phenomena.
Dario: Can consciousness be studied using the scientific method, or does it inherently resist such an approach due to its subjective nature?
Pietro: I firmly believe that consciousness can and should be studied scientifically. We can investigate both its functional aspects—how consciousness is used in processing information—and its phenomenal aspects, the subjective experience of being aware. Some argue that these two dimensions are irreconcilable, but I think they are simply two facets of the same phenomenon.
Take the example of experiencing music. Imagine listening to two different performances of the same symphony—one grand and dramatic, another more restrained. Your subjective impression of each is not just an illusion; it has a real impact on how you perceive and react to the music. In the same way, I believe we can find scientific ways to study even the most subjective aspects of consciousness.
Dario: What about artificial consciousness? Do you think machines could ever develop consciousness similar to that of humans?
Pietro: I don’t subscribe to the view that everything in the universe has some form of consciousness. However, I do believe that certain artificial systems could develop forms of consciousness if they meet specific conditions.
In my view, consciousness is tied to the ability to form and use representations of the world. Many animals show evidence of this, and there are even indications that artificial intelligence may be moving in a similar direction. However, for true artificial consciousness, an AI system would need to go beyond processing data and exhibit something akin to self-awareness or inner experience.
Dario: You’ve mentioned that consciousness may have evolved primarily for social purposes. Can you elaborate on that?
Pietro: Yes, I believe consciousness is fundamentally a tool for social cognition. Many assume that our social nature developed first, and self-awareness emerged as a byproduct. However, I argue that it is the other way around: self-awareness enhances our ability to navigate complex social interactions.
Being able to reflect on one’s own thoughts allows for better prediction of others’ actions, more effective communication, and improved coordination. This might explain why species with sophisticated social structures tend to exhibit more advanced forms of self-awareness.
Dario: If consciousness is so closely tied to social interaction, does that mean it requires a body? Could a purely digital AI ever be conscious?
Pietro: That is a crucial question. Some aspects of consciousness, such as bodily awareness, clearly require a physical presence. However, the kind of self-reflective consciousness we are discussing might not necessarily depend on a body.
For example, researchers working on AI have created systems that engage in inner dialogue, mimicking the kind of internal monologue that humans experience. These systems use self-reflection to refine their problem-solving abilities, which suggests that at least some aspects of consciousness can emerge in non-biological systems.
Dario: Speaking of AI, recent models have introduced features like self-reflection and reasoning steps before producing an answer. Some argue that this brings AI closer to something resembling consciousness. Do you agree?
Pietro: It is fascinating to watch these models work, especially when they display reasoning processes before arriving at an answer. This mimics human cognition in a way that previous AI systems did not. However, while they may simulate some aspects of consciousness, they still lack essential components—such as emotions, personal stakes, and a genuine sense of responsibility for their decisions.
Dario: That brings up another issue: responsibility. If AI becomes increasingly autonomous, who should be held accountable for its actions?
Pietro: That is a pressing concern. Some argue that AI developers or companies should bear responsibility, while others suggest a system of insurance, similar to how we handle liability in car accidents. However, as AI systems become more complex and capable of making independent decisions, traditional notions of accountability may no longer apply. This is an ethical challenge that society must address urgently.
Dario: Finally, do you see AI as an invention or a discovery? Are we creating something entirely new, or are we uncovering something that has always existed in nature?
Pietro: That is a thought-provoking question. In a way, AI is like human flight. Before the invention of airplanes, flight was considered an inherent ability of birds. Once we understood the principles of aerodynamics, we created artificial flight. Similarly, intelligence was once thought to be unique to biological organisms. Now, we are discovering that intelligence follows certain principles that can be replicated in machines.
In that sense, I believe AI is more of a discovery than an invention. We are uncovering the fundamental laws of intelligence, much as we once uncovered the laws of flight.
Dario: Thank you, Pietro, for this fascinating conversation. We have touched on so many deep and complex topics, and I am sure this will leave our listeners with a lot to reflect on.
Pietro: Thank you, Dario. It was a pleasure discussing these ideas with you!
