Dr. Lewis Yablonsky, a sociologist who’d written a book called The Hippie Trip, argued that many hippies were “lonely, alienated people”: Even when they act as if they love, they can be totally devoid of true compassion. That is the reason why they can kill so matter-of-factly… Many hippies are socially almost dead inside. Some require massive emotions to feel anything at all. They need bizarre, intensive acts to feel alive—sexual acts, acts of violence, nudity, every kind of Dionysian thrill.
