I guess you just have to try it.
Make one article. Make it a standalone article about one topic. (Not an introduction to a planned long series of articles; just write the first article of the series. Not just the first half of an article, to be continued later; instead choose a narrower topic for the first article. As a general rule: links to already written articles are okay, but links to yet unexisting articles are bad; especially if those yet unexisting articles are used as an excuse for why the existing articles don't have a conclusion.)
Put the article in Discussion; if it is successful and upvoted, someone will move it to Main. Later perhaps, when two of your articles were moved, put the third one directly in Main.
The topics seems interesting, but it's not just what topic you write about, but also how do you write it. For example "The Layers of Evolution": I can imagine it written both very good and very badly. For example, whether you will only speak generally, or give specific examples; whether those examples will be correct or incorrect. (As a historical warning, read "the tragedy of group selectionism" for an example of something that seemed like it would make sense, but at the end, it failed. There is a difference between imagining a mechanism, and having a proof that it exists.)
If you have a lot of topics, perhaps you should start with the one where you feel most experienced.
The Fuzzy Pattern Theory of Identity could reasonably be created as a stand alone post, and probably the Layers of Evolution too. Guided Tour and Strange Loop of Consciousness too, though I'd rather have a few easier ones done before I attempt those. The other posts rely on one or both of the previous ones.
Glad they seem interesting to you :). And yes, layers of evolution is the one I feel could go wrong the most easily (though morality and maths may be hardest to explain my point clearly in). It's partly meant as a counterpoint to Eliezer's post you linke...
Previous Open Thread
You know the drill - If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should start on Monday, and end on Sunday.
4. Open Threads should be posted in Discussion, and not Main.
