Spoilers for Harry Potter lore. “Horcrux” is a metaphor here. In the story, a real Horcrux is a profoundly evil object created by splitting the soul through murder.[1] Writing a blog does not literally split your soul. Deadlines may disagree.
1. At some point, a diary stops feeling like a diary and starts feeling like distributed storage for the self
When people write about old experiences, they can preserve more than events. They can preserve what felt wrong, what made them angry, what they laughed at, what question bothered them, and what they sensed before they had the words to explain it.
Years later, opening that article can bring back an old way of seeing the world.
“That is what bothered me back then.”
“I can finally explain why.”
“Apparently I have been getting annoyed by the same structural problem for years.”
The archive is no longer just a timeline. It has become an external place where pieces of one’s former perspective are stored.
That is why the Horcrux metaphor lands so well.
Seven pieces? Cute. Once the archive passes a thousand articles, the soul needs commit hashes.
Do not give your Horcruxes CI/CD.
2. In lore it resembles a Horcrux; in function it is closer to Tom Riddle’s diary plus a Pensieve
The official encyclopedia describes a Horcrux as an object containing a concealed fragment of a person’s soul.[1]
Tom Riddle’s diary is an especially useful comparison. It was his first Horcrux, and the official description notes that it lets a reader relive memories.[2]
Functionally, a lifelog also resembles the Pensieve. The Pensieve stores memories so they can be reviewed later, and even entered by another person. The Hogwarts Pensieve accumulated memories from generations of headmasters, creating a reference library for those who came later.[3]
So an article-based lifelog combines three ideas:
- the Horcrux feeling of leaving part of yourself outside your body;
- the diary feeling of an old self becoming active again;
- the Pensieve function of storing memories for later examination.
That is an alarming amount of wizarding infrastructure for a personal blog.
3. What gets preserved is not only what happened, but where your attention went
Facts can often be searched later. A shop opened on a certain date. A rule changed. A fictional event happened. A product cost a certain amount.
What disappears more easily is your original reaction.
Different people notice different things in the same event. One notices efficiency. Another notices fairness. Another notices power. Another notices that a system has no obvious safeguard against the same failure happening again.
Writing preserves that direction of attention.
After enough entries, the archive can reveal something different from a life chronology:
What kinds of things have repeatedly made me react?
4. Old articles can revive an old self because personal memory is tied to identity
Psychologists use the term autobiographical memory for memories of one’s own life that are connected to the sense of self across time.
Research suggests a two-way relationship between memory and identity. Present beliefs and goals shape how people interpret earlier selves, while remembered versions of the past also influence the current self.[4]
Other work describes how people build broader life stories and how repeatedly important memories can become self-defining.[5][6]
Reviews commonly group the functions of autobiographical memory into guiding future behavior, supporting social connection, and maintaining a sense that the person of the past and the person of the present belong to one continuing life.[7]
An article is not the memory itself. But it can be an unusually strong doorway back to the perspective from which that memory was once understood.
5. Why researched articles can become stronger “reboot devices” than ordinary diary entries
A diary preserves immediacy. That is valuable.
A later article does something different. It takes an old “something felt wrong,” researches the surrounding system, evidence, history, psychology, or fictional canon, and then gives the old reaction a clearer explanation.
One article can therefore contain two versions of the writer:
- the earlier self who noticed something but could not yet explain it;
- the current self who now has better language and evidence.
The result is not just preservation. It is collaboration across time.
In version-control terms, the goal is not to overwrite the old emotional state with the newest interpretation. The better model is to keep history and add a new commit.
Force-pushing your life story destroys the audit trail.
6. At scale, isolated memories become a dataset of your recurring patterns
One article may be an accident. Hundreds or thousands are a pattern detector.
Repeated reactions start to appear: irritation at unexplained role expectations, a reflex to redesign inefficient systems, sensitivity to gaps between stated rules and actual practice, discomfort when people are reduced to labels, or a tendency to turn even heavy situations into jokes once the structure becomes visible.
This is more informative than simply declaring, “I am this kind of person.”
The archive shows what actually kept triggering attention over time.
A memory collection gradually becomes a dataset of one person’s thinking habits.
7. The archive is not the past itself
Memory is not a video recording. Current knowledge, goals, and feelings influence how earlier experiences are reconstructed.[4]
So an article written years later does not preserve the original moment perfectly. The present self is already editing it.
A useful practice is therefore to keep layers separate:
- what you remember noticing then;
- how you interpret it now;
- what remains uncertain.
That lets a future self revise the interpretation without deleting the earlier layer.
At that point, “Horcrux” may be less precise than version-controlled selfhood.
8. Conclusion — a lifelog can become more than a box of memories
When a lifelog stores not only events but also discomfort, anger, questions, jokes, and values — and later turns them into researched articles — its function changes.
It becomes a way of sending forward the answer to a strange question:
What was my past self looking at?
In Harry Potter terms, the emotional metaphor is the Horcrux, the reactivation metaphor is Tom Riddle’s diary, and the review-and-analysis function belongs to the Pensieve.
Keep doing this long enough and the archive becomes a map of recurring reactions, decisions, changes, and values.
Voldemort aimed for seven.
A lifelog can pass a thousand.
No immortality involved. Your past selves are simply being served through a CDN.
