Silo warned to be doubtful of political change through reforms; in Siloist thought, all change has to start with the individual. In fact, early Siloists rejected the idea of participating in party politics, though they later revisited this and started the Humanist Party in many countries. Under the pseudonym "H. van Doren", Silo criticised then-governing communist party Popular Unity for preserving the capitalist system, instead proposing a "total revolution" lead by young self-transformed people that would result in libertarian socialism, a communist society without hierarchies.
