Finally some good research on LSD in humans. Very interesting finding about the increased connectivity to the visual cortex. It certainly vibes with my anecdotal experience -- the whole visual world just seems more meaningful and 'in focus'. Tripping in an art gallery can be a real treat :)
I can't believe I never thought of doing that.

I did ecstasy and i did LSD. Ecstasy is like a lie in this quote comparison. You get high in the beginning and it brings you down at the end, really awful feeling at the end. LSD is different, i experienced world differently even for couple of days after i took LSD. World seemed different. I knew what was important in life and what not, very clear. I can't describe how you feel on LSD, and people that didn't took LSD…
It sounds like LSD convinced you that you knew that stuff, without you actually knowing it. There are plenty of mental conditions where people are mistaken about what they know. You make it sound like this is a positive thing, I'm not convinced. If LSD actually gave you that insight, then maybe. But to give you the certainty without actually having the knowledge doesn't seem valuable. For example that snail - did you…
Meaning only exists between our ears -- it's not some intrinsic attribute of reality. I, for example, experience bouts of depression, where nothing about the world around me has changed, and yet my perception of (and feelings about) it becomes melancholic and devoid of purpose or meaning.
If you walk away from an experience with a renewed sense of meaning or purpose, even if you can't give a rational reason for such changes, I would think that would still be a good thing, no?
Re: Brain scans reveal how LSD affects consciousness
#43Pretty cool. I'd like to point out that meditation might have a similar dampening effect on the default mode network as well. http://www.ncbi.nlm.nih.gov/pubmed/25904238 The question arises again, can psychedelics have lasting effects or is meditation the only way to create permanent positive change in that direction? Finally, a quote from a letter to Osho: "Many people are experimenting with the drug ecstasy. I hear…
@nefitty, you posit that the diminishment of the self is a "permanent positive change." But you didn't provide any evidence. The reductio of your argument is that it's better to just be matter, since no self is involved. Few will agree with you.

Sorry to hear about that :( The first time I took LSD (not hallucinogens in general, but LSD) went sort of similarly for me. Of course a life provides many confounding factors, but I ended up depressed and anxious for about three or four months afterwards. Took me a while to work my way out of it. I still think it was a worthwhile experience, but my symptoms weren't as bad as yours sound. I hope you're making a good…
> I ended up depressed and anxious for about three or four months afterwards Holy shit, that sounds awful.

For a counterpoint to this - I decided to do 150 micrograms of LSD after reading a lot about it on HN, talking with many friends that had tried it or do it fairly regularly and reading as much as I could find (Sam Harris, Huxley, What the Dormouse said etc.). Nothing can really prepare you for it - the dream like state, the visuals and just the capacity of how different things can be. When looking at things I saw the…

#46That is the most "lit up" MRI scan that I've ever seen. Obsessive compulsive people have highly activated brains, and I know musicians activate many parts of the brain - but not like this.
Interesting comment on OCD, given that I have the disorder. Could you link me a source for that claim? Many friends of mine study neuroscience so I'm inadvertently becoming more interested as an amateur.

I would not consider this a bad trip. More like a rude awakening. Had you gone through something else in real life, major trauma of sorts, you may have experienced exactly the same... half life of LSD is about 5 hours, which means in about 30 hours, most of it > 99% was gone from your body, but your head/brain was still attached :), meaning, whatever your worldview was, got shaken to the core for one reason or another...long after the LSD was gone.
If everyone who tried it had an experience, or rather, epiphany such as yours, we'd all be so lucky.... and maybe the world would be slightly better place than it is today. Unfortunately, few if any experience reflection upon using drugs, pot, LSD or whatever, and continue to abuse them rather than deal with the pain of what's going on (mostly angst and integrity/identity issues that fester for decades sometimes) in better ways.
EDIT: I've never tried LSD, though I've been tempted after reading many testimonials on Erowid from some really smart people who did it to 'see what it's like to have your mind bent'.... Guess I'm too chicken to try it.

"Diminishment", not "negation". A reductio argument is only valid if the assertion whose absurd terminal case you're highlighting is actually part of the original claim. You're making a straw man here.

Perhaps you really saw the "bitter truth" as GP put it for the first time? I really don't mean this in a patronizing way. More that powerful drugs like this have a tendency to show you things about reality both good and bad that you otherwise would never have known. The discoveries you make can reverberate for years. The resulting bum out about the bad things (and I guess the stoke for the good things) can manifest s…
That's exactly what happened. He saw the cosmic joke of existence.

A reductio does not suggest that an argument is false. It is instead a tool that is useful for contrast enhancement. The real meat of the point I made is that there cannot be evidence for the OP's claim. It's just an opinion founded in OP's spiritual preference, which is apparently to not exist as such.
You're once again mischaracterizing the actual claim, and in a way that suggests you not only disagree with it, but feel a need to mock it. Please don't do that.
