"When you have established that one alternative is good and the other is evil, there is no justification for the choice of a mixture. There is no justification ever for choosing any part of what you know to be evil."

Previous Quote

The hippies had in mind something that they wanted, and were calling it freedom, but in the final analysis freedom is a purely negative goal. It just says something is bad. Hippies weren't really offering any alternatives other than colorful short-term ones, and some of these were looking more and more like pure degeneracy. Degeneracy can be fun but it's hard to keep up as a serious lifetime occupation.
