Sarah Walker discusses assembly theory, AI and consciousness, evolution of minds, and exploration of original life studies. Topics include combinatorial spaces, information shaping complex structures, and the interconnection of life, mind, and consciousness.
Objects are assembled through evolution and selection, emphasizing the role of evolutionary history in determining structure.
Information plays a crucial role in constraining the space of possibilities and enabling the construction of complex objects like minds.
Assembly theory introduces measurable properties like assembly index and copy number, highlighting the recursive nature of evolutionary processes in determining object structures.

Objects are Assembly of Historically Contingent Trajectories
Objects are viewed as being assembled over time through evolution and selection, following causation through an informational process. The theory of assembly focuses on constructing objects from a more fundamental understanding, emphasizing the role of evolutionary history in determining the structure and properties of objects, including minds.
Information is Fundamental in Understanding Life and Minds
Information is highlighted as a key aspect in the theory, indicating that objects and their properties arise as products of evolution, learning, and selection. The theory suggests that understanding the nature of existence, consciousness, matter, and life requires considering the role of information in constraining the space of possibilities and enabling the construction of complex objects like minds.
Assembly Theory: Constructing Objects via Selection and Recursion
Assembly theory posits that objects emerge through a recursive process of assembly, where each object is built from previously constructed components, following distinct and observable causal operations. The theory introduces the concepts of assembly index and copy number as key observable properties to measure the construction and repetition of objects, emphasizing the recursive nature of evolutionary processes in determining object structures.
Assembly Index Measure on Molecules in Mass Spec
The podcast discusses how an assembly index is a measurable feature for real molecules, analyzed through mass spectrometry. Lee Cronin contributed assembly theory to assess whether a system was evolved using mass spec measurements. The feature, assembly index, is not limited to mass spec but also applicable to NMR and infrared measurements, demonstrating measurability across different techniques.
Assembly Theory, Complexity, and Evolution
The podcast delves into the concept that complex objects can only exist within physical systems capable of constructing them. These objects are products of evolution that require successive generations of objects creating more advanced structures. Imposing an assembly threshold predicts the observation of any object unless selected not to exist, offering insights into using assembly theory for alien life detection. It shifts the focus from specific molecules to exploring whether systems exhibit evidence of evolutionary construction and informational acquisition over time.
Sara Walker discusses the importance of viewing life and consciousness through the lens of assembly theory, arguing that our understanding of alien life, the origin of life, and consciousness itself could be fundamentally expanded by examining the combinatorial possibilities within chemical and informational spaces on Earth, rather than searching outer space. This presentation was recorded at MindFest, held at Florida Atlantic University, CENTER FOR THE FUTURE MIND, spearheaded by Susan Schneider.
