Read this, and/or listen to it, if you have the time and inclination. It is a lecture by Ayn Rand which was published as “Apollo and Dionysus”. Listening takes you back in an odd way, to a time when the concept of a public and popular intellectual was much less foreign (although Jordan Peterson is sort of bringing it back): https://campus.aynrand.org/works/1969/01/01/apollo-and-dionysus/page5
There are a LOT of quote-worthy lines in here, but the point I will focus on is that these hippies–and this type, of course, is very much still with us–are united by fear, not love. They use drugs to medicate their fear, not to express higher potentials. All you have to do is watch behavior, and ignore the words.
Check it out. It has aged extremely well.
