The invasive tyranny practised in boarding-schools by the boys themselves, which Mr. Phipson cites in his letter in the present issue as the strongest argument against Anarchism within his knowledge, is not an argument against Anarchism at all. It is an argument against the doctrine of non-resistance. The proneness of some people to confound these two things is hard to understand. Anarchism does not assume that all people will voluntarily refrain from invasion, but undertakes to discipline by force those who persist in invasion.
