Douglas d'Enno is right to call for a blue plaque in Kemp Town to commemorate Peter Kropotkin's stay in Brighton (The Argus, June 12-13).

I can remember sitting at Kropotkin's table, donated by him to the Trades Council, in the old Labour Club in London Road. He was a revolutionary, a writer and a scientist. His work must not be forgotten.

Particularly important is his book Mutual Aid which countered the crude Darwinism used to justify Victorian individualism.

Like Dr King, he emphasised the need for co-operation and found examples among animals of self-sacrifice and mutual help.

A Russian prince, he could have led a life of luxury, but chose, as did Tolstoy, to oppose Tsarism and adopt an Anarchist philosophy that defied the state and proposed a society based on freedom and voluntary co-operation.
