According to Peter Marshall the "circled-A" represents Proudhon's maxim "Anarchy is Order." [ Demanding the Impossible p. 558] Peter Peterson also adds that the circle is "a symbol of unity and determination" which "lends support to the off-proclaimed idea of international anarchist solidarity." [ "Flag, Torch, and Fist: The Symbols of Anarchism" , Freedom , vol. 48, No. 11, pp. 8] However, the origin of the "circled-A" as an anarchist symbol is less clear.
