The purge crushed Most's belief in gradual reform. He became convinced the system could only be changed by blowing it up – and suddenly realised that explosives were now lying all over Europe and the US, in sheds controlled by ordinary workers. Dynamite needed no expertise to operate; it could be carried in your pocket; and it could kill. He announced: "It is within the power of dynamite to destroy the capitalist regime just as it had been within the power of gunpowder and the rifle to wipe feudalism from the face of the earth. A girdle of dynamite encircles the world!"

Most travelled from country to country, urging workers to pick up their dynamite and use it against the bosses who forced them to work 12-hour days, seven days a week, for starvation wages. He became the model for Ossipon, the refugee-anarchist Ossipon in Joseph Conrad's novel The Secret Agent, who walks the street with a bomb forever strapped to him, ready to blow himself up the moment the police swoop. In anticipation of Islamism, Ossipon brags that his enemies "depend on life ... whereas I depend on death, which knows no restraint and cannot be attacked. My superiority is evident."
