For me, the repetitive objectification of women was infuriating with little payoff. Perhaps it is true that his inability to evaluate women by any measure other than their attractiveness is symptomatic of the general lack of self-expression and open communication in the society, but this doesn't change at all after he experiences the souls of women through psychedelic use (even as his understanding of others in general grows.) The second half of the book was more interesting than the first as he starts to explore psychedelics, but there are probably better books out there if a fictional representation of 60s/70s drug culture is what you're looking for.
