Memetics is the study of evolution of culture and ideas, in all their expressions. Science, technology, philosophy, all evolve, and our tools for creating, evaluating, agreeing on and implementing ideas with them.
We have huge challenges ahead of us, and the best tools are science and reason to face, solve, and overcome them. It is at the same time important to recognize that art, poetry, emotions are also part of culture, and they evolve memetically as well.
