“I came to realize that exaggerated concern about what others are doing can be foolish. It can paralyze effort, and stifle a good idea. One finds that in the history of science almost every problem has been worked out by someone else. This should not discourage anyone from pursuing his own path.”
The Wind and Beyond, 1967

Context: In love, no one can harm anyone else; we are each of us responsible for our own feelings and cannot blame someone else for what we feel. It hurt when I lost each of the various men I fell in love with. Now, though, I am convinced that no one loses anyone, because no one owns anyone. That is the true experience of freedom: having the most important thing in the world without owning it.

Context: There will not be one kind of community existing and one kind of life led in utopia. Utopia will consist of utopias, of many different and divergent communities in which people lead different kinds of lives under different institutions. Some kinds of communities will be more attractive to most than others; communities will wax and wane. People will leave some for others or spend their whole lives in one. Utopia is a framework for utopias, a place where people are at liberty to join together voluntarily to pursue and attempt to realize their own vision of the good life in the ideal community but where no one can impose his own utopian vision upon others.
