Graham Harman, a philosopher of object-oriented ontology, joins cognitive scientist Donald Hoffman, known for his work on perception, and philosopher Mazviita Chirimuuta, who specializes in the philosophy of mind. They dive into the captivating question of whether our perceptions truly reflect reality or are merely evolutionary adaptations. Topics include the perception paradox influenced by synesthesia, the indirect nature of accessing reality, and the limitations of human cognition. They also discuss the diverse perceptions of non-human entities, inviting a reevaluation of consciousness.
Evolution shapes human perception to prioritize survival over an accurate understanding of reality, resulting in a functional but illusory experience of existence.
The debate highlights that while human perceptions are limited, objects possess an independent individuation that suggests a richer, multi-layered reality beyond our senses.
Deep dives
The Nature of Perception and Reality
Evolution does not equip us to perceive an objective reality accurately; instead, it shapes our senses to provide useful perceptions for survival. For instance, synesthetes experience flavors as distinct three-dimensional shapes, enabling them to navigate the culinary world effectively, even if these perceptions do not reflect objective truths. This notion extends to all creatures, where the visual and sensory abilities are tailored to enhance survival rather than deliver an accurate depiction of reality. As a result, evolution acts as a user interface that conceals the underlying truths of existence, prioritizing functionality over factual representation.
Individuation and Object-Oriented Ontology
Debate arises around the status of objects in reality, with one perspective suggesting that while objects may not correspond to our perceptions, they still hold a form of individuation independent of human interpretation. The existence of different sensory experiences among animal species highlights this complexity, as creatures like octopuses have unique modes of interacting with their environment, allowing them to perceive in ways entirely foreign to human experience. However, the discussion suggests the need for a layered understanding of reality, where human perceptions contribute but do not wholly define the characteristics of objects. This viewpoint emphasizes that reality encompasses more than human-centered experiences, suggesting an underlying structure that supports various forms of perception.
The Relationality of Truth and Reality
Human perception is inherently limited, leading to a nuanced understanding of truth that acknowledges our inability to grasp a 'god's eye view' of the world. It's posited that perceptions, such as color, arise from relational properties between human sensory systems and objects, rather than as independent attributes. This perspective shifts the focus from seeking an absolute truth to appreciating the validity of human-related properties, suggesting that these interactions with the world hold intrinsic value in understanding reality. Despite the inherent limitations, striving for a deeper comprehension of reality remains a worthwhile endeavor, as it fosters growth and leads to better-informed perspectives.
The Evolving Nature of Scientific Theories
Scientific theories serve as powerful tools that help us navigate our understanding of reality, but they are not necessarily absolute truths and are subject to revision and improvement. The dialogue emphasizes the continuous search for deeper structures beyond space-time, highlighting the limitations of existing theories and the need for new frameworks of understanding. Despite the disintegration of fundamental concepts such as space and time, scientists maintain that exploring theoretical models can yield valuable insights into the nature of consciousness and existence. This iterative process acknowledges the probabilistic nature of scientific inquiry, where each theory aims to refine our grasp of reality while remaining open to future transformations.
We are working toward a true account of the universe, and the world we see around us is an accurate picture of reality. Or so most of us believe. At the same time we think we, along with our experience, are a product of evolution. Yet evolution is driven by survival not by truth. Some scientists go further and argue that evolution rules out even the possibility that we experience an accurate and true account of reality.
Should we conclude that while our biology enables us to successfully function in the world, our experiences and theories are illusions rather than truths? Is the theory of evolution itself flawed, unable to account for the truth of the theory itself? Or can we fashion a new account of ourselves that would give us a better way to understand both who we are, the process of evolution, and our relationship to reality?
