A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming.
The most popular seem to be lighthearted, clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts: 1
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- If you feel strongly that you want politics back, please volunteer as a mod.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report the message goes away and you never worry about it.

I mean to be honest I wouldn’t say that we “die” at all when you sleep… your mind is extremely active while sleeping, it’s just disconnected from motor control.
It's way more than just that, though. You're also disconnected from your sensory inputs, and furthermore, your conscious experience is interrupted. It's not like you're just in a sensory deprivation tank, because there you'd still experience conscious thought, and the passage of time. It just seems to turn off for a while.
Plus there are periods of deep sleep when your brain does shut down quite thoroughly. People just don't remember those, obviously, so they put a lot more weight on the dreaming bits that slip through sometimes.
I mean, without defining what the self is and consciousness, it's difficult to even define what death is from a consciousness point of view. A living meat bag doesn't require brain activity either. There's a whole range of things. So even assuming we have a good meaning of "death" is oversimplifying things.
We have a good definition of "death", it's the irreversible stop of some activity. For a brain, that's neuronal depolarization; for a body organ or cell, it's destruction past its ability to regenerate.
The self, is a snapshot of a brain state at a certain moment, which is technically irreversibly disappearing 30 times a second, but we like to think of it as just "changing" and forming a causal sequence we call "consciousness".
This threshold has changed over time. So I don't think it's a good definition of it hasn't always been the same point.
And the rest of your comment is just philosophy. You're neither wrong nor right. Definition of self is not a concept there's really any consensus over.
Threshold has changed, the definition is still the same, we're just getting better at reverting the stop of some activities, like breathing or heartbeat. If we someday could revert neuronal depolarization, that would be great, but it seems difficult to achieve.
The other part is not just philosophy, it's the best we can do to define a "self". The philosophical part is only whether we can consider them a continuum, or whether we have to see them as usually similar but separate (there are reasons to support both versions).
If the threshold changed, the actual definition changed. The same words to describe a different point. If the definition described two different things, its changed. That's basic and simple reasoning. If a definition no longer describes the same thing, it's because it's actual meaning has changed.
"To the end of the road" doesn't change meanings when the road gets extended another 10 miles. The point changes, the definition doesn't.
yes, the definition changes. it used to mean one point. now it means a point 10 miles away. come on. simple substitution. if you define it only with relative terms then its poorly defined as there's no actual concrete meaning. so you either have a poorly defined term or you have a term that has changed meaning over time. which still makes it poorly defined. i don't know how else to explain it. so i'm going to leave it here. this is going in circles.
I think I know what you mean, but plenty of terms have relative definitions ("behind", "bright", "x+1", "etc"... etc). If you're looking for an absolute point, you won't find one, because their meaning is the relationship itself.
Both "life" and "death" define a state relative to another. The definition of "life" is a particularly tricky one, because it includes multiple relative definitions like "growth", "reaction", "functioning", and a "reproduction" that includes both cloning and "imperfect" cloning. Being "death" the opposite, it's necessarily as relative and tricky too.
Which is the crux of this whole conversation. We don't have an actual definition of death. It's all relative and changing over time.
What surprises me, is you wouldn't accept the relative/changing definition as a valid definition itself.
Guess that could be an interesting conversation, potentially shedding some light on different worldviews... but I don't really know where to begin. Curious.
I refer you back to my original comment involving the impact of not having a good definition of death and what that causes.
Your definition does not clarify any of the resulting problems arising from trying to define all the other concepts.
It's a good definition for some scenarios, but not at all or in any way, this one.
Not even that sometimes. I'm told I can do some pretty mean kicks while I sleep.
