Just want to echo someone else's sub-thread:
Adderall is not at all similar to Huxley's description of Soma. Soma was about feeling good and not having to think of the evil things that make the BNW society possible, not efficiency.
That's also what I thought - Wasn't Soma more of a way to make people question less and just remain in a blissed out but maybe sort of out of it state at all times ? Seems very different than amphetamines
The link (including the transcript of Huxley’s lecture) doesn’t seem to be about Soma, unless I’m missing something. Huxley produced a lot of work outside of Brave New World, lots of it concerned with drugs and altered states of consciousness (so much so that personally I don’t think I’ve done enough drugs to understand his perspective, as I find him distinctly, and almost uniquely among such high-profile authors that I’ve tried, unreadable)
