Historical resistance to integrating empirical areas into philosophy in Europe: Europe's philosophical landscape was shaped by a complex history, including a strong emphasis on history, a negative view of naturalism, territorial attitudes, and personal experiences, leading to a rift between analytic and continental philosophy, but efforts have been made to reconnect and reestablish a global philosophical discourse.
The resistance to the integration of empirical areas into philosophy, particularly in Europe, has a complex history. This resistance took various forms, including a strong emphasis on the history of philosophy, a negative view of naturalism, and a territorial attitude towards who is allowed to answer certain questions. The European commitment to continental philosophy also played a role in this divide. The aftermath of World War 2, which resulted in the murder or exile of many Jewish intellectuals, further isolated Germany from the global philosophical conversation. Personal experiences, such as discovering the atrocities of the Holocaust at a young age, also deeply impacted the philosophical landscape in Germany. These historical events created a significant rift between analytic and continental philosophy, but efforts have been made to reconnect and reestablish a global philosophical discourse.
The Role of Philosophy in the Holocaust: Philosophy, particularly the works of Martin Luther and Nietzsche, influenced the antisemitic ideology of the Nazi regime, contributing to the Holocaust. Misinterpretations and misuse of these philosophies were dangerous and prepared the ground for tragic events.
The Holocaust was a tragic event in history that was not openly discussed or taught in schools during the speaker's upbringing in Germany. The speaker expresses shock and disbelief that such atrocities could have occurred in their own country, and questions why and how this could have happened. The study of philosophy played a significant role in understanding the intellectual and moral foundations of the Holocaust, with figures like Martin Luther and Nietzsche being identified as having contributed to the antisemitic ideology that fueled the Nazi regime. The misinterpretation and misuse of Nietzsche's philosophy by the Nazis is a particularly intriguing aspect of this history. The speaker emphasizes that these ideas were dangerous and not innocent, and served as a preparation for the horrors that followed.
The disconnect between historical records and personal experiences during the Holocaust: Despite the official narrative, many people were unaware of the Holocaust. Germany's culture of self-criticism contrasts with denial in other countries. Acknowledging the aftermath of current events is crucial for future generations.
While the official narrative of history portrays widespread knowledge of the Holocaust during that time, personal experiences and anecdotes suggest a different reality. Many people, including children, were unaware of the atrocities being committed. This disconnect between individual experiences and historical records raises questions about the accuracy and completeness of historical accounts. Moreover, the speaker's personal experience as a German adds a unique perspective to current events in the US. Germany, which has lived in a culture of self-criticism since World War 2, contrasts with countries like Austria and Japan, where denial of their morally dark pasts is more prevalent. However, the speaker's father's experiences challenge this narrative, revealing a level of denial and trauma among survivors. The speaker also emphasizes the importance of acknowledging the aftermath of current events. Trump's presidency may not last long, but the impact on future generations will. Parents will be asked by their children about their actions during this time, and it's crucial to consider the lessons and legacy of the past as we navigate the present.
Climate Change: A Long-Term Threat: While political turmoil is significant, climate change poses a greater long-term threat and requires immediate attention and action.
While the political turmoil caused by figures like Donald Trump may seem significant and impactful in the present, the consequences of climate change will last for centuries and pose a much greater long-term threat to society. The US, under Trump's leadership, has become a "climate rogue state," isolating itself from the rest of the world on this critical issue. While it's important to acknowledge the potential dangers of Trump's actions, it's equally important to focus on addressing the larger issue of climate change and its impact on future generations. The intergenerational rift caused by political divisions is a concern, but it pales in comparison to the existential threat posed by climate change.
Hope for military intervention in US politics, recognizing potential consequences, and the complexities of consciousness: The speaker expresses hope in the military to intervene if democratic norms are disregarded in US politics, emphasizes the importance of recognizing potential consequences, and predicts significant progress in understanding consciousness by 2050, dismissing the 'hard problem of consciousness' framing
The current political climate in the US raises significant concerns about the potential disregard for constitutional and democratic norms. The speaker expresses hope in the higher ranks of the American military to peacefully intervene if necessary. As a scholar of history, the speaker emphasizes the importance of recognizing the potential consequences of electing a leader who disregards these norms, drawing parallels to experiences in other democracies. Regarding consciousness, the speaker stresses that it is a complex issue with various aspects, including attention, sensory discrimination, and conceptual issues. The consciousness community has made significant progress in understanding these aspects, and the speaker predicts that by 2050, we will have a better grasp of consciousness as a whole. The speaker also expresses a dismissive attitude towards the "hard problem of consciousness" framing popularized by philosopher David Chalmers, viewing it as outdated and not productive for serious research in the field.
Understanding the subjective experience of consciousness: Despite advancements in understanding the neural mechanisms of consciousness, explaining why and how subjective experience emerges remains an open question in the field.
Consciousness is the subjective, qualitative perspective that living beings have on the world. This perspective, as philosopher Thomas Nagel famously asked, is akin to asking "What is it like to be a bat?" The easy problems of consciousness, such as how the brain processes information, are separate from the hard problem, which is explaining why and how this subjective experience emerges from unconscious processing. Even if we were to discover the exact neural mechanisms responsible for consciousness, it might not feel intuitively satisfying as an explanation, as it would not explain the emergence of consciousness itself. This remains an open question in the field of consciousness studies.
The mystery of consciousness and the hard problem: Consciousness is a complex phenomenon that can't be explained by laws of nature alone, as it's not logically connected to physical processes, making it a deep epistemological mystery.
Despite advancements in molecular biology and other fields, the nature of consciousness remains a mystery and is not easily explained by mechanistic means. The hard problem of consciousness refers to the fact that phenomenal properties, like the experience of sweetness or redness, only supervene nomologically (under the laws of nature in our universe) upon functional properties, but not logically. This means that consciousness may only exist in our world with these specific laws of nature, and it's not conceptually possible that it could exist without any subjective experience. The idea of a zombie, a being that functions like a human but has no consciousness, is an intriguing thought experiment, but it's unclear if such a being is actually possible. Ultimately, the hard problem of consciousness is a deep epistemological mystery, as it's difficult to conceive how subjective experiences emerge from physical processes.
Understanding Consciousness in Machines: Intuitions and Complexity: Intuitions, though limited, can contribute to scientific theories, but understanding consciousness in machines poses unique challenges. Complexity alone doesn't explain consciousness, and ethical considerations demand we ensure advanced AI is truly conscious before deployment.
While we may build advanced AI that passes the Turing test and appears conscious, without fully understanding the nature of consciousness itself, we cannot be certain if these machines truly possess consciousness. The speaker argues that intuitions, though limited, can still play a role in scientific theories, but consciousness seems to present unique challenges. The idea that complexity alone explains consciousness is not satisfactory, and the speaker questions the value of intuitions in this context. The speaker also discusses the potential for creating conscious computers, given our current understanding of the neural correlates of consciousness in humans. However, without a clear understanding of how consciousness arises, there is a risk of creating machines that seem conscious but may not actually be sentient beings. Ethical considerations demand that we strive to ensure that any advanced AI we create is truly conscious before we unleash it into the world.
Understanding machine consciousness remains elusive: Despite efforts to understand consciousness in machines, potential suffering and fundamental differences make creating conscious machines a challenge.
While we can strive to understand the computational processes behind consciousness, intuitive satisfaction and self-awareness may remain elusive, even if we discover the global neural correlate of consciousness in machines. The speaker argues against creating conscious machines due to potential suffering and the unknown nature of machine consciousness, which could be fundamentally different from human consciousness. The challenge lies in mapping our own phenomenological experiences to fine-grained computational descriptions, and understanding if and how these experiences are instantiated in machines. Additionally, the speaker raises the point that just as we cannot fully understand what it feels like to be a bat with its unique sensory experiences, we may never truly grasp the nature of machine consciousness.
The Illusion of Self: The self, a deeply held belief in consciousness, may be an illusion. It's not just a sensory misrepresentation but also includes emotions, interoceptive self-model, and bioregulation. No scientific evidence supports an immortal soul or self in the brain. Understanding its origin and explaining self-consciousness in simpler terms is a complex challenge.
The concept of the self, though deeply ingrained in our understanding of consciousness, may be an illusion. While people are not illusions themselves, the idea of an unchanging, thinking self inside our heads is a misrepresentation. This misrepresentation is not entirely sensory, but also includes our interoceptive self-model, emotions, and bioregulation. Despite this, there is no scientific evidence for an immortal soul or self in the brain. The emergence of this robust sense of selfhood in a system devoid of such concepts is a counterintuitive phenomenon. Even those who believe in the absence of a self, like the Buddha, have reported experiencing it through practices like meditation or psychedelics. The challenge lies in understanding how this illusion arises and how we can explain self-consciousness in a more parsimonious way.
