A meme is works like a gene in a cultural setting. A sort of programming one could say. Daniel Quinn suggests that this strong meme guides our culture:
Civilization must continue at any cost and cannot be abandoned under any circumstance.
The meme has been built up generation by generation since we started farming about 10-12.000 years ago. The ultimate purpose being to protect this new way of life that we created then. He also writes:
Ours is the one RIGHT way for people to live and everyone should live like us.
The “right way”, by the way, is farming. Almost all human life today derives from the premise of farming.
