In your twenties, you were a visionary. You wanted to learn it all, and fix it all. All the world.

Ever realized that you cannot do everything that is meaningful in your life? When you dedicate your life to help people with HIV, you can't go find a cure for HIV. Or find the quantum gravity model. Or develop sustainable government. Or find out and teach us all about the Transcendental and God (if you find there is God). Or clean up all the landmines. Or the ocean plastic. Or invent a fair-for-all mode for economic exchange. Or this. That.

Because your lifetime is limited.

And then you realize, it would be great to at least achieve one of these. And then you focus on that one.

And then you realize, you have neither time or money for even one of these meaningful contributions (… contributions to what, actually?). Because your parents might be old, needing your help. Or you made children, just like everyone else, and now have to care for them. Or you got fired from your job, the bank took your house, and now you're living in a tent. That you found in that garbage can. It's just a tarp actually. Or you get medical conditions, so you can be happy to make it through the day.

Because your lifetime is limited.

And then you realize, your life will pass and end as meaningless as everyone else's life. And life, what is life? It then seems like a meaningless aggregates of matter to you. You, yourself, just a bunch of atoms, with your conscience an unnecessary (and unpleasant) emergence of it.

And you start to enjoy that your lifetime is limited, not your limited lifetime.

Stop that.

Now, come back to your visions.

Just change one thing: it should be no longer your vision, now it's ours. Humanity's. We are all in our twenties again.

Everyone who has given up on seeking, and expecting to see, the abolition of greed, poverty and evil, and the introduction of immortality and freedom for all, has given up living while alive. Seek, and expect, again. Because now we seek, and expect, together. You were frustrated by your powerlessness as an individual. Now marvel at what seven billion can do. And what God will do, if there is a God, and seven billion seek him.

Yes, you should expect and seek God, because there might be God after all. But do not forget all the rest of what is good. Physical immortality. Good governance structures. Unextinction of animals. Desert forests. The Theory of Everything. Space colonization. So much before us!

Now what? It's all about how we organize. If your grandma cooks a simple healthy meal for scientists working on quantum gravity, she contributes. If you read news about political quarrels, visit touristic spots from your hard-earned surplus money, engage in any avoidable consumption, you do not.

Wake up, all of us!

The pieces are coming together already. Take note, organize yourselves, contribute. Some inspirations? Here you go:

And of course: Are we alone in the universe? What does it all mean? Are we sure about this? Why? Re-asking the big questions is probably one of our biggest challenged. Us modern folks got so used to the scientific storied of Big Bang, cosmic evolution, and biologic evolution. And now, scientific evolution comes along and puts to question the very concept of space-time. And with it, the existing notion of Big Bang.

Now, what?

This is so far just a proposal – I did not fully test it out yet, but have exlored options for two days and this seems best, for my requirements. (And thanks to mantas in the comments, whose tip for Docear lead to this major rework of an earlier article, which was using Freemind instead.)

Solution Proposal: Docear + Zotero

Tool collection

My proposal uses the following tools, which you should install (available for both Windows and Linux):


[TODO: Show how to use Dropbox or an open source replacement for it to sync your (cited, and only those) fulltext files with annotations to your server. And how to password-protect those fulltext files that cannot be published to everybody, using an efficient command that adds to a .htaccess file.]

  1. Document collecting. Whenever you find an interesting document on the web, use the Zotero browser plugin to create a literature entry in your Zotero group. Use tags to mark documents you have read and want to read. Create attachments to the entries, linking to the online fulltext of these articles.
  2. Finding what to read.
    1. Use your Zotero browser plugin or standalone application to browse through your group's shared bibliography and select items you want to read.
    2. Download them with Zotero to your "Literature" directory and name them according to their key in Zotero, plus your author shortname (example: Gantt2001.matthias.pdf). This is because this file will contain your annotations, and files with other author suffixes will contain their annotations.
    3. Add a (hypothetical) web links to your annotated file as attachment to the respective literature entry in your Zotero group. This will enable other researchers in your group to see your notes, once you read the file and uploaded it to this place.
  3. Reading and annotating. All files you want to read will now appear in your in Docear, because you added them to your Literature directory. Order them into your reading list in Literature & Click the links there to start reading, with PDFXChange as your PDF reader. Create annotations, bookmarks and text highlighting as desired in PDFXChange, and save. To simplify your later task of finishing your own articles, you should include in every bookmark, annotation and highlighted text the source, in brackets; for example "[Gantt2001, pp.21]".
  4. Mobile reading and annotating (optional). [TODO]
  5. Note organizing and drafting with Docear. 
    1. Click "Refresh" in your Docear's to get your PDF bookmarks, notes and annotations into Docear.
    2. If you intend to create a thesis, you want to use a dedicated mindmap for its draft, else drafting multiple articles in one mindmap seems most comfortable.
    3. I like to create an "inbox" node in the mindmap and collect all my ideas into that whenever you don't have the time to find a more appropriate place for them.
    4. Create an initial table of contents as a hierarchical node structure in your article / thesis draft mindmap.
    5. Add, copy, move nodes and rework your table of contents hierarchy until the textual part of your thesis is done. For me that means, until the written thoughts form collections that I consider drafts for the article(s) I want to write. Finishing the wording and getting the sentences connected properly can be done more comfortably in LibreOffice.
    6. You can click the links of bookmark, annotation and highlighted text notes to look them up in their original document, which is in my view the greatest feature in Docear.
  6. Writing and publishing with WordPress.
    1. Sync to Zotero. That is, sync your Zotero literature database to the Zotero server; necessary because it will be accessed by your ZotPress and Enhanced-BibliPlug plugins.
    2. Copy and paste your article draft. You can just copy your complete list of draft notes into a WordPress post and start editing it from there.
    3. Finish your article. 
    4. Replace text refs with real literature references. You will of course lose the link information then, but as you added the literature refs before to the bookmarks, notes etc. (like "[Gantt2001, pp.21]"), this is not much of a problem. Just double-click to select a literature key of such a reference, copy it, then insert a corresponding literature reference with ZotPress by pasting the key in its dialog. [TODO: How can this be more automated? Selecting the text and using a key combination would be enough. Maybe possible by configuring the rich text editor for inserting a special tag that way, if ZotPress recodnizes literature references in text based on tags.]
    5. Insert links to fulltext files (optional). You can make the "p.xy" part of literature references a regular hyperlink to a PDF file, with a subpart marker to let it go to the page of bookmark conforming to the citation. And for faster own use that also shows your annotations etc., you can add the an analogous link afterwards, leading to the corresponding offline file on your own computer using a file://~/Data/Literature/key.authorname.pdf scheme. I would recommend to make the public link resolve directly to the original article on the web, if possible via a DOI resolver, and not to your annotated version, proving that you cite unchanged material. You might add a link to your public, annotated version afterwards. I like to use Unicode icon characters for these last two links for compactness. My proposals:
      • ⛁: "Squared Plus" (U+229E) for "annotated document" and "White Draughts King" (U+26C1) for "local hyperlink" because it looks like the missing hard disk symbol.
      • ⌂: "Strictly Equivalent To" (U+2263) for "annotated document" and "House" (U+2302) for "local hyperlink".
    6. Upload fulltext files (optional). Upload them into a directory of your own server; using Zotero server space is also possible, but can be quite expensive. Needed when you inserted links to individual pages etc. in them, see above. Also needed when you inserted links to them as files in your reference list, which can be needed when the work is not publicly accessible. You will have to password protect access to these links, but at least you can thus share these files with the researchers in your group.
  7. Writing and publishing with LibreOffice. The advantages over WordPress are more advanced formatting options in LibreOffice, and the option to create a high-quality PDF version from it without manual efforts. Which is both needed when writing for journals, but else, writing directly in WordPress seems like the simpler variant for writing about your research and publishing it on the web. Except of course you have no Internet access, then LibreOffice is best (even if you just use it in HTML mode, basically as a HTML editor for later copying into WordPress).
    1. Copy and paste your article draft. Just as when writing for WordPress. If it's a long and structured draft in Docear, like for a thesis, you better export it as follows, to get your table of contents structure over into LibreOffice as well:
      1. Unfold the mindmap so that all notes belonging to TOC headings are visible, but not more.
      2. Then export to .odt format in Docear. The visible nodes will become the headings there, and thus will be included into the TOC when you add a "Table of Contents" directory into your LibreOffice document.
      3. Open the .odt document in LibreOffice and transform the formatting from hard-coded to style-based. [TODO How can this be done efficiently?]
    2. Replace text refs with real literature references. Just as when writing for WordPress. [TODO: There has to be a feature to convert selected text into a literature reference.]
    3. Insert links to fulltext files (optional). Just as when writing for WordPress. But to link to local fulltext files, you can't use the "file://" URL scheme in LibreOffice, such links are automatically converted to "smb://". Instead, use relative paths to files, without any directory prefix. That's because you will view your article locally in PDF format after it's finished, and then it resides in your own "Literature" files directory, as your own publication alongside all those of others.
    4. Add a link to the PDF version. At the beginning of the document, create a link to the PDF version of it. As this PDF will be part of your regular literature database, just create an entry in Zotero for it and link to it with the same scheme you use for linking to online fulltext versions of cited works.
    5. Remove links to local fulltext files in a copy (optional). Links to local fulltext files are only relevant for yourself, so you might want to hide them in the version that is published on the web. Removing these links is simple, even though LibreOffice supports no links in conditional text: if you used symbols as link text, just search&replace them with nothing.
    6. Export to PDF. Be sure to check "Export links relative to the filesystem." in the PDF export options in LibreOffice. Place the PDF into your "Literature" directory.
    7. Upload fulltext files (optional). Just as when writing for WordPress. Includes uploading the PDF version of your own article.
    8. Publish in WordPress. Should be as simple as exporting from LibreOffice to HTML, copying the HTML into WordPress and (optionally) replacing the textural literature references with ZotPress references. This however means manual work whenever doing changes to the article, so probably you better leave that out.
  8. Viewing your web-published content. It is not ideal to use the Firefox integrated PDF viewer for viewing annotated PDFs; while it correctly understands subpart links (like #2 for "page two") and shows annotations and bookmarks, it does not show highlighted text. So better open links to annotated PDFs in Adobe Reader or PDF-XChange, except you know you're not interested in the highlightings this time.
  9. Cleaning the literature database. You might think from time to time that some document that you once included in the literature database is not worth storing any more. But if you cited it, you should. So there should be a command to determine if you cited a specific work, identified by its BibTex key (which is the same as its file basename). If not cited, delete the file and all references in Docear mindmaps.


My last thesis was written in (now LibreOffice), and the one feature I really missed there was a comfortable way of moving notes, snippets and other parts of text around. Because getting a thesis done is, for a good part, just that: ordering and integrating notes and snippets that you wrote whenever you had an idea or insight.

Since that thesis, I became a FreeMind enthusiast, using it for nearly all my personal information management. It's truly great in this "ordering notes" task because three aspects come together: it's speedy enough in displaying and dragging even large mindmaps; it provides good optical clues for quick visual navigation in a huge hierarchical content structure, making it mentally less strenuous to work with it (unlike scrolling text in OOo or using OOo outline mode); it provides great keyboard shortcuts for quick navigation and reordering of nodes in the hierarchy. So I looked for a mindmap-based tool for scientific writing, and the above is what I found.

My reasons for individual aspects of this solution:

  • Why Zotero. This is my current recommendation for a reference management tool for LibreOffice, see my evaluation of reference managers for LibreOffice. Of course you could try to use Docear with integrated JabRef reference manager for reference management, see the discussion of the alternative below for the reasons why Zotero is used here. In any way, you will want a separate reference manager rather than treating references as just another node that you organize with Docear. Becuase a mindmapping tool is rather poor with structured data, it's no all-understanding knowledge management system by itself. Also, collaborating on a common bibliography would be difficult with such an approach.
  • Knowledge, not just cited works. This is a knowledge management system; that's why the literature database contains everything you think is worth storing, and not just works you cite or have annotated or have even read.
  • Docear for note management, not reference management. Note that we don't use Docear for literature reference managemet at all, we don't export anything from Zotero to Docear (although that's possible). That's because so far, there is no way to insert text with inline references from Docear nodes into LibreOffice so that it will contain LibreOffice literature references, and also no way to copy or insert a complete node with a link to a literature work from Docear into LibreOffice so that it will appear there as literature reference. The only thing we could do is use JabRef and JabRef plugins for LibreOffice to manually select literature entries from the Docear bibliography and create LibreOffice literature references from them. But that can equally well be done with Zotero and its LibreOffice plugins, plus, Zotero has a more efficient way of collecting document metadata when browsing the web, which is why we avoid JabRef. So there's no meaning in having the literature database available in Docear at all: Docear is used for notes and drafting, while references are only needed when finishing an article. Of course it still has to be easy to detect to what work of literature a note or quotation in an article drafted in Docear belongs; but that is possible in our system, as the PDF file link will contain the literature key as its filename, a scheme that has been tried and tested in practice.
  • Why not Semantik? Looking for mindmapping software for scientific writing, I found Semantik, a tool developed with just this purpose in mind. However, I found its current (as of 2011-08) version in several aspects more limited than FreeMind, while I found Docear to be more powerful than Freemind, esp. because of the PDF annotation management.
  • Why no collaborative annotating? In a group of researchers it will have some benefits if all can annotate the same work of literature and at the same time, see the annotations of others in there. In our solution, there is one file per author with his / her annotations on the contained work of literature. By downloading others' annotated versions into your Literature directory, Docear will import these annotations as well, so that the set of all annotations from all authors is then available in Docear instead of in a single PDF. This is a much simpler system, as it avoids concurrent edits and sync conflicts when editing one file in parallel. No functionality and not much convenience is given away.
  • Why Chromium? Because some WordPress rich text editors, or at least some functions of them, are horribly slow on some systems in Firefox because of some JavaScript functions being slow there. If it does not affect you, you may as well use Firefox.
  • Why not CiteULike? Zotero was preferred above CiteULike because it is completely free software (though this is not a big issue, as CiteULike offers your literature data in various download formats for you).

Alternative Solution Proposal: Docear + JabRef + BibSonomy

There is an alternative solution without Zotero, thus saving one separate software and also integrating funcionality tighter. However, it misses the sophisticated metadata grabbing features of the Zotero browser plugin, and also the Zotero "scientific social bookmarking" online groups are much more and the service more well-known than newcomer BibSonomy (though they offer interesting features like a WordPress plugin). Still, some might rather want this solution. In this solution, you would use these tools:

  • BibSonomy website. For reference collecting in your team.
  • JabRef. The reference manager integrated into Docear.
  • JabRef standalone. Additionally to the Docear integration using it as a standalone reference manager, for some added options.
  • JabRef plugins for LibreOffice. To insert JabRef references into articles you write.
  • BibSonomy plugin for JabRef. To collaborate with your group via the BibSonomy "scientific social bookmarking" website as an alternative to Zotero online groups and CiteULike.
  • AcademicPress WordPress plugin. Together with an online copy of JabPress's BibTeX file if you want to write directly in WordPress
  • BibSonomy CSL plugin for WordPress. To show your complete group bibliography in WordPress

This world has only two big unsolved problems. First, the truth about God is not apparent (so people cannot believe the right thing easily). Second, people are bad (so people cannot live in freedom and peace and sustainable manner).

It’s an important insight that these are disconnected problems: even if Christianity is the right religion, and is applied large scale to the whole earth, people are still bad on average, and the world will not become a free and peaceful and sustainable place. Because, there is much power abuse and exploitation of both people and nature in “Christian” nations, and also by Christians.

So we need two solutions. I propose Second Acts for the first problem, and EarthOS for the second.

Yesterday I met a guy from church who suffered a stroke in his thirties. More precisely, two strokes. He has no problems of this remaining, none at all. This is strange, because it is  unlikely, though not impossible. So this could be a “live miracle”.

It was hard to believe that this guy had suffered stroke at all, him standing before me and joking and talking and walking as he ever did. And here is the lesson from it: miracles are not necessarily visible. The absence of lasting injury can also be a miracle. And also, miracles are not necessarily emotionally accessible; as in this case, where emotions are unchanges from meeting him the last time, as the situation is seemingly unchanged. Emotions react to situational / senseable changes, but in “invisible” miracles, there are no such changes.

Each individual person can do nothing better than to find and use the best epistempology (a method for determining truth) for which he or she has the resources to use it. As this will return the best possible results, while even better but utopic epistemologies return no results at all.

Therefore, people in ancient cultures (before using exact science was possible in societies, because of economic restrictions) could do nothing better than to employ historic documents, traditions and faithful witnesses to determine the truth about God. The same applies to developing countries today.

Also today, as and as long as an individual has no practical access to using scientific methodology when it comes to questions about God, the best thing is to apply the ancient’s epistemology. It’s not as good, but at least can be maintained by an individual person.

Which means: as long as I cannot execute my Second Acts project (to quasi-empirically collect facts about God’s contemporary activity), I should (and also I am epistemically allowed to) believe in Jesus Christ because of history, traditions and own (not exactly recorded) experiences alone.

God might be far away, meaning answers to prayer and messages from God are really, really rare. At least in the Western world at this time. And it is difficult to deal with that distance, it is something “unlivable” to put all ones hope into something that will not (or nearly not) come into experience in this life.

A means to deal with this situation could be to develop a sense of awe. God might be far away (thought not absent, means you can still find some signs of him). But he is so great that he is sufficient even in that distance. This becomes apparent when studying his work in nature: the human body, the laws of nature etc..

In the recent article “Third way cont., up to the end” I said that it would be “the last to the “Second Acts” series of posts, canceling that project resp. leaving it to be “just some visits” while on my tour through Africa.”. This is no longer true … I realized in the time since then that I simply cannot or do not want to believe life-long in something that is just in “the Book” but not in my experience.

It felt “unlivable” to be doomed, as a Westerner, to in effect have a deistic God for ones time on earth. For Westerners also, experience is something totally different than knowledge: knowledge is the informational representation of experience. Knowledge might be enough to believe (and I do believe because I know something about God from history), but it is not enough to have living, life-giving, life-long hope for eternal life.

If the existence of eternal life depended, in some strange way, on the existence of the charm quark c, I think I would also be interested to know for sure and by personal observation (“experience”), rather than just from some physics books in the library.

But I will probably not come back to the scientific style that the “Second Acts” project originally had. Such a thing is over my limits in terms of time and money. It will be “just some visits” in Africa, but with substantial results and documented per video.
