The Free Energy Principle and Existential Imperatives
42:29 - 57:03 (14:33)
The free energy principle suggests that if something exists, it must mathematically optimize a particular quantity, as seen in the properties exhibited by an oil drop that must preserve its boundary. This principle can be interpreted as turning the probability of existing into evidence of existence, seen in the configuration of macromolecules in computational chemistry.

The free energy principle is a formal statement that suggests systems that manage to survive in a changing world can be interpreted as an inference problem where probability of existing can be seen as evidence that you exist.

Summary
The free energy principle is a formal statement that suggests systems that manage to survive in a changing world can be interpreted as an inference problem where probability of existing can be seen as evidence that you exist. The principle is based on data analytic approaches to high dimensional time series data from the brain, and suggests that if something exists, it must exhibit properties that make it appear to be optimizing a specific quantity.
