There is a concept in biology called "punctuated equilibrium": organisms can display little discernible change over long periods of time before sudden, sharp, and profound changes. Without wishing to give credence to teleological or determinist views, it does seem that human history is profoundly dialectical. Sharp change that bewilders an apologist for the status quo can inspire and give hope to those of us who believe that a better world is possible. We live in interesting but depressing times today. Neoliberal ideas are hegemonic. The old collectivist values of the labor movement have been submerged in a tide of market fundamentalism, summed up in Margaret Thatcher's claim that "there is no such thing as society; there are only individuals and families." When I began researching for my Silvertown book, it became apparent to me that a similar flood tide of liberalism had washed over much of nineteenth-century Britain. This portrayed the status quo as normal, natural, and inevitable, but the equilibrium was punctuated in the last decades of the century.
