So what is a meme then? I know the "popular definition" but epistemologically it means nothing.
One new way of looking at it, which has probably developed from the meme concept is like this:
"Participatory Epistemology is a relatively new philosophical concept, paradigmatically articulated by Richard Tarnas and elaborated specifically in relation to Transpersonal psychology by Jorge Ferrer, Christopher Bache, and others. The Participatory Epistemology is constituted in the recognition that meaning is neither outside of the human mind, that is, in the "objective" world waiting to be discovered (the paradigmatically Modern/Structuralist worldview), nor that meaning is simply constructed or projected onto an inherently meaningless world by the "subjective" human mind (the paradigmatically Postmodern/Poststructuralist worldview). Rather, Tarnas argues, via Hegel, Goethe, Kuhn, Jung, and many other thinkers, that meaning is enacted through the participation of the human mind in the larger meaning of the cosmos. Thus, as in the dialectical movement that Hegel describes, the mind draws forth a meaning that exists in potentia in the cosmos, but which must go through the process of articulation by means of human consciousness.
