When trying to understand thought and memory, the transition from a biological, cellular scale to the one of abstract understanding happens seamlessly. It is no longer possible to think of the brain as a computer composed of circuits prefabricated by the genes. To the contrary, connections between nerve cells are gradually established over time - the evolutionary competition inside the brain takes over from the biological evolution of species and creates, as a consequence, organic links with the physical, social, and cultural environment, tying the structure of thinking to the topology of the brain. Their configuration is in a permanent flux, contributing to many realities. Repetition and difference fight in a constant battle against the erasure of entropy through time - inexact by essence, not by accident.
