A Brief History of Anarchism
Humans are social beings, and the kind of creature that a person becomes depends crucially on the social, cultural and institutional circumstances of his life. We are therefore led to inquire into the social arrangements that are conducive to people's rights and welfare, and to fulfilling their just aspirations—in brief, the common good.
For perspective I'd like to invoke what seem to me virtual truisms. They relate to an interesting category of ethical principles: those that are not only universal, in that they are virtually always professed, but also doubly universal, in that at the same time they are almost universally rejected in practice.
These range from very general principles, such as the truism that we should apply to ourselves the same standards we do to others (if not harsher ones), to more specific doctrines, such as a dedication to promoting democracy and human rights, which is proclaimed almost universally, even by the worst monsters—though the actual record is grim, across the spectrum.
A good place to start is with John Stuart Mill's classic On Liberty. Its epigraph formulates “The grand, leading principle, towards which every argument unfolded in these pages directly converges: the absolute and essential importance of human development in its richest diversity.”
The words are quoted from Wilhelm von Humboldt, a founder of classical liberalism. It follows that institutions that constrain such development are illegitimate, unless they can somehow justify themselves. Concern for the common good should impel us to find ways to cultivate human development in its richest diversity.
