I'm sort of surprised; this thread has been viewed over 170 times but no one has been able to provide me with the scientific proof that memes exist. I understand that they are a metaphor to describe an analogy, but that doesn't provide scientific proof that the concept of the analogy for which memes is a metaphor is even true.
What surprises me about this is that I'm very sure that many people believe in memes due to the teachings of Dawkins. But surely before that belief comes the knowledge to back up or prove their existence. If memes are still theoretical and hopefully one day science will back up the metaphor, or they're such an abstract concept that a level of hope in their existence is necessary, surely that falls into the category of faith. And isn't faith delusional?
