About Susan Blackmore's memes and t(r)emes...

I attended this Sunday a lecture given by Susan Blackmore on genes, memes, and tremes. 

Here are in a nutshell my thoughts about it:

The lecture was very entertaining and interesting. Susan appeared as a jovial, youthful and clever woman. Furthermore, she shares many of my interests (consciousness, free will, genes, memes, meditation, out of body experiences, near death experiences, ..).

Here is what I understand about genes, memes, and tremes after having reflected on Susan's lecture:

1/The earth is the environment that enabled the first replicator (gene) to arise. It happened because the earth had what it takes a) to create replicating entities, b) to allow modifications of these replicators, and c) to select amongst these various replicators.  These replicators first simply freely floated around, then they started having phenotypes that helped them catalyzing their own reproduction (e.g. serving as template to the formation of enzymes,...) and ultimately they created gene survival machines (living organisms). In this process, the replicators maybe migrated from RNA to DNA. These organisms are sub-environments that carry out all three processes of copying, varying and selecting (via e.g sexual selection) genes while part of the selection is still performed by its environment, the earth.

2/One of these organisms (humans) became the environment that enabled the second replicator (meme) to arise. It happened because the human mind can a) create and replicate ideas, b) modify them, and c) select them. Memes first simply floated around from one mind to another, then they started having phenotypes that helped them catalyzing their own reproduction (e.g. writing, paper, ...) and ultimately they created meme survival machines (e.g. computers, internet,...). In this process, the meme migrated from neural patterns to binary codes. Computers are sub-environments that carry out all three processes of copying, varying and selecting memes while part of the selection is still performed by its environment, the human mind. 

Susan appeared to have a slightly different opinion, she argues that humans are meme machines. I first arrived at another conclusion. I considered that we are the meme's environment, just like the earth is the original replicator's environment. I considered that we are not meme machines because memes did not create us, let alone create us to propagate themselves. Not like genes, that indeed created organisms to propagate themselves. If the earth was a conscious Gaia, before the appearance of living organisms, she could mistakenly have thought that she was a gene machine since she creates, modify, and select replicators. However, after having further thought about it, I can see how we can indeed be considered meme machines since we perform the tasks of copying, varying, storing and selecting memes.  

3/ Well, yet another replicator (treme) might arise within these new meme machines that are the computers, internet, ... but I do not think it arose yet. I think we are still at the level of the meme. However, I share Susan's view that a major change occurred: (Technological) Meme Survival Machines recently appeared and they will evolve to better serve their masters (the technological memes). The memes might indeed ultimately not need us anymore. 

If Susan Blackmore give a lecture in your neighborhood, I can safely recommend it to you.
