Susan Blackmore's Theory of the Self

Susan Blackmore is a scientist who is most famous for studying memes, with the book The Meme Machine (2000). It's a bit outdated at this point though. She's also a skeptic in debunking some pseudoscience.

I'll start with two videos:

Memes and Tremes

Susan Blackmore studies memes: ideas that replicate themselves from brain to brain like a virus. She makes a bold new argument: Humanity has spawned a new kind of meme, the teme, which spreads itself via technology -- and invents ways to keep itself alive
Living Without Free Will
When I say that consciousness is an illusion, I do not mean that consciousness does not exist. I mean that consciousness is not what it appears to be. If it seems to be a continuous stream of rich and detailed experiences, happening one after the other to a conscious person, this is the illusion.

Clenes and Genes: Evolution of clay and the genetic takeover

This post is heavily based on Tim Tyler's page. It has lots of dead pictures, so view them on the Internet Archive if you see them.

Genes are not the only thing that can copy themselves. Computer virus, RNA, protein virus (prion), and chain mails, they all can.

The idea of non-gene replicators is not new. Richard Dawkins proposed memes in The Selfish Gene (1976), and Graham Cairns‑Smith proposed clay-genes (clenes?) in The origin of life and the nature of the primitive gene (1966). Genes and memes are getting all the popularities, but clenes aren't, so I'll summarize clene theory. A detailed explanation is here.

Overview of clenes and genes

First we check the 1966 paper's abstract:
Life on earth evolved through natural selection from inorganic crystals.
During the formation of a crystal, certain kinds of lattice imperfections usually replicate as a necessary part of the crystallization process.
... the primitive genographs were patterns of substitutions in colloidal clay crystallites. (The theoretical information density in such a crystallite is comparable to that in DNA.)... A gradual “take-over” of the control machinery by organic macromolecules—a genetic metamorphosis—is then considered to have occurred.

Let's Read: Neuropath (Bakker, 2009)

Neuropath  (Bakker 2009) is a dramatic demonstration of the eliminative materialism worldview of the author R. Scott Bakker. It's very b...
