The Journal of Libertarian Studies, Vol. VI, No. 1 (Winter 1982), p. 87 (online; PDF p. 5): "Tucker was definitely aware of Molinari's work and at least one of Molinari's books was reviewed in Tucker's magazine. He shared Molinari's view that the production of security was an economic commodity which could be better supplied by the free and unhampered market, thus going beyond the criticism of Herbert and Spencer and, arguing with Molinari, that the market could offer a positive and practical alternative to state monopoly defense."
↑“within the strictly anarchist world we find some theorists like Ricardo Mella, who, due to his knowledge of the English language, knows deeply the work of (Benjamin) Tucker and that of the north American individualists, especially by reading regularly the British magazine Freedom and the north American ones The Alarm (Chicago) and the tuckerian Liberty (Boston)…Uncomfortable within the polemics between collectivists and libertarian communists, the Galician anarchist tries to integrate the different ideological currents under the proposal of Tarrida del Mármol of an anarchism without adjectives. ” Diez, X.
