"In a global setting, contextualism asks this question: How can we best defend all life and the entire planet from the massive and unrelenting assault of global capitalism, centralized political rule, militarism, and the metastasizing growth of the human empire colonizing the earth and monopolizing its resources? Questions concerning the legitimacy and efficacy of physical force cannot be answered in the abstract, but only in specific contexts. Whereas partisans on both sides want to read the history of moral progress as driven exclusively by nonviolence or violence, the fact is that social change unfolds through the entire arsenal of pressure tactics, which include strikes, protests, demonstrations, boycotts, sabotage, liberation, education, legislation or even armed struggle."
