"The universe is built on a plan the profound symmetry of which is somehow present in the inner structure of our intellect." - Paul Valery. Clean Architecture is great! Let's try that again…Clean Architecture is beautiful! Clean Architecture is symmetric! Clean Architecture is natural! Clean Architecture should really be common sense! Clean Architecture is the structure that naturally emerges when truly applying DIP: "High level modules should not depend on low level modules. Both should depend on abstractions"
