We rejoice and feel proud that our science makes it possible for us to exploit the energy of a waterfall and make this power work in factories, or that we have pierced tunnels through mountains, and so on. But the trouble is that we make this power of the waterfall work not for the benefit of people, but for the enriching of capitalists, who produce objects of luxury or tools for destroying human beings. The same dynamite with which we blow up mountains to make tunnels through them, we also use in war, which we not only do not want to renounce, but which we regard as necessary and for which we are constantly preparing.
