With an account, you can revise, criticize, and comment on ideas.I don't think a gene has problems. It does not have ideas.
A gene doesn’t have problems in any conscious sense, but it always faces the problem of how to spread through the population at the expense of its rivals.
Maybe that answers your question, Erik.
How could we integrate that vision with Popper's definition (paraphrased): a tension, inconsistency, or unmet explanatory demand that arises when a theory clashes with observations, background assumptions, or rival theories, thereby calling for conjectural solutions and critical tests.
The rival theories and clashes sound like competition between genes – or more precisely, between the theories those genes embody.
Basically, genes contain guesses (in a non-subjective sense) for how to spread through the population at the expense of their rivals. Those guesses are met with selection pressure and competition.
Yeah, thanks! Are ideas also guesses of how to survive in the mind and across substrates, or is there more to ideas?
In the neo-Darwinian view, any replicator’s primary ‘concern’ is how to spread through the population at the expense of its rivals. This view is what Dawkins (IIRC) calls the gene’s eye view, and it applies to ideas as much as it does to genes. Any adaptation of any replicator is primarily in service of this concern.
So I think the answer to your question, “Are ideas also guesses of how to survive in the mind and across substrates …?”, is ‘yes’.
Most people (except in Alzheimer's, etc.) don't run out of memory in the brain. The reason most people don’t (permanently) run out memory (of either kind) isn’t that memory isn’t scarce, but that there’s a pruning mechanism in the mind. And there’s competition.
In your revision, you asked me to let you know if you are doing things incorrectly.
You can revise ideas the way you did, it’s not wrong per se, but revisions are better for incremental changes. They’re not really meant for taking back criticisms or indicating agreement. If a criticism of yours is successfully counter-criticized and you would like to abandon it, I would just leave it counter-criticized and not revise it further.
If you are looking for a way to indicate agreement (with a counter-criticism, say), it’s something Dirk and I have been discussing offline, see #2169. I hope to implement something to that effect soon.
#2325 serves as an example. I had submitted a criticism which is now outdated and remains counter-criticized. It’s actually better that way because it shows that an error has been corrected, and makes it less likely for others to submit a duplicate criticism.
