The Memes were constantly at war. They fought for control of memespace, the universe in which they lived. Sometimes competing memes, such as science and religion, shared a common memespace locality in an uncomfortable coexistence. But as long any two unique memes existed there could never be peace.
Some memes utilized others, such as patriotism or religious duty, in a bid to destroy the memspace of their enemies. At best this achieved only limited successes.
Eventually science architected a new memespace from the very fabric of time and space where it alone would exist.
The universe awoke and examined itself.
