A lot of people I know believe that ideas and concepts are things called 'memes' (a concept created by Dawkins), and that ideas and concepts evolve and become extinct in the same way as biological organisms do, in accordance with Darwinian ideas of evolution (if I'm correct about the idea). I'm a bit suspicious of this. I'm wondering if there are any among you that feel the same as me about this meme idea, or if I am rejecting something which is accepted by almost everyone?
