Ricard Solé, a complexity theorist and ICREA research professor, explores the intriguing landscape of cognition across different life forms. He discusses the 'space of cognitions' and considers whether liquid brains, like those of slime molds, could rival solid intelligence found in humans. The conversation touches on single-celled organisms' ability to learn, the evolution of neurons and comparisons between biological and artificial intelligence, and the unique dynamics within ant colonies. Solé emphasizes the importance of understanding these complexities for advancements in AI and cognitive science.
The concept of complexity in cognition can be studied as a field itself, encompassing various complex systems like the brain.
Neural networks and threshold elements play a crucial role in information processing and decision making in cognitive systems.
There are diverse forms of cognition beyond solid and liquid brains, including organisms like slime molds and plants, raising questions about unexplored forms of cognition.

Complexity and the Study of Cognition
This podcast episode explores the concept of complexity and its relationship to the study of cognition. The host and guest discuss whether it is possible to study complexity as a field of study itself, rather than just studying individual examples of complexity separately. They emphasize the importance of narrowing in on specific complex systems, such as the brain, to gain a deeper understanding of complexity and intelligence. The guest also introduces the idea of liquid brains, which are systems where individual units can move and interact in different ways, and how they compare to solid brains with fixed neuronal connections. Overall, the episode raises questions about the space of cognition and the potential for exploring new forms of intelligence.
The Importance of Neural Networks and Threshold Elements
The podcast delves into the significance of neural networks and threshold elements in the study of cognition. The guest suggests that neural networks, characterized by interconnected neurons, play a vital role in information processing. These networks, which exhibit emergent behavior, can store memories and make predictions. Additionally, the concept of threshold elements is discussed, highlighting their ability to integrate signals and make decisions based on a specific threshold. The guest argues that the presence of threshold elements and multi-layer structures in cognitive systems, whether biological or artificial, indicates their efficiency for information processing and decision making.
Exploring Different Forms of Cognition
This episode explores various forms of cognition beyond solid and liquid brains. It highlights the unique properties of organisms like slime molds and plants, which have distinct cognitive features. For instance, slime molds exhibit emergent behavior and problem-solving capabilities, while embodying a liquid-like structure. On the other hand, plants demonstrate morphological plasticity and gather energy from the sun, showcasing a different kind of cognition. The podcast also raises the question of unexplored forms of cognition and the potential to engineer novel cognitive systems in the future.
The Challenges of Mimicking Human Intelligence
The podcast delves into the challenges of replicating human-like intelligence in artificial systems. It emphasizes the limitations of current AI models, which primarily rely on large-scale neural networks without true understanding or consciousness. The guest argues that true intelligence involves factors like language complexity, abstract thinking, and theory of mind, which are yet to be effectively integrated into AI systems. The discussion explores the significance of embodiment and the importance of incorporating concepts like embodiment and cultural acquisition to achieve more advanced AI models. Furthermore, ethical implications are considered, with a focus on motivations and intentions in AI systems.
The Space of Cognition and Unexplored Possibilities
The podcast concludes with a discussion on the space of cognition and the possibilities for new cognitive systems. The guest notes that there are still unexplored regions within the space of cognition, where no cognitive systems have been observed. Speculation arises as to whether it is due to limitations in natural evolution or if these regions can be engineered or created in silico. The potential of synthetic biology to explore and experiment with cognitive systems is highlighted, allowing for the interrogation of natural systems and the creation of novel cognitive architectures. The episode ends with an acknowledgement of the ongoing research and the excitement surrounding the exploration of cognition.
Octopuses, artificial intelligence, and advanced alien civilizations: for many reasons, it's interesting to contemplate ways of thinking other than whatever it is we humans do. How should we think about the space of all possible cognitions? One aspect is simply the physics of the underlying substrate, the physical stuff that is actually doing the thinking. We are used to brains being solid -- squishy, perhaps, but consisting of units in an essentially fixed array. What about liquid brains, where the units can move around? Would an ant colony count? We talk with complexity theorist Ricard Solé about complexity, criticality, and cognition.
