A short zine collecting an introduction to the concept by Matt Colquhoun that appeared in 'krisis journal for contemporary philosophy Issue 2, 2018: Marx from the Margins' and the unfinished introduction to the unfinished book on Acid Communism that Mark Fisher was working on before his death in 2017. "In this way ‘Acid’ is desire, as corrosive and denaturalising multiplicity, flowing through the multiplicities of communism itself to create alinguistic feedback loops; an ideological accelerator through which the new and previously unknown might be found in the politics we mistakenly think we already know, reinstantiating a politics to come." —Matt Colquhoun

Socialism is the watchword and the catchword of our day. The socialist idea dominates the modem spirit. The masses approve of it. It expresses the thoughts and feelings of all; it has set its seal upon our time. When history comes to tell our story it will write above the chapter “The Epoch of Socialism.” As yet, it is true, Socialism has not created a society which can be said to represent its ideal. But for more than a generation the policies of civilized nations have been directed towards nothing less than a gradual realization of Socialism.17 In recent years the movement has grown noticeably in vigour and tenacity. Some nations have sought to achieve Socialism, in its fullest sense, at a single stroke. Before our eyes Russian Bolshevism has already accomplished something which, whatever we believe to be its significance, must by the very magnitude of its design be regarded as one of the most remarkable achievements known to world history. Elsewhere no one has yet achieved so much. But with other peoples only the inner contradictions of Socialism itself and the fact that it cannot be completely realized have frustrated socialist triumph. They also have gone as far as they could under the given circumstances. Opposition in principle to Socialism there is none. Today no influential party would dare openly to advocate Private Property in the Means of Production. The word “Capitalism” expresses, for our age, the sum of all evil. Even the opponents of Socialism are dominated by socialist ideas. In seeking to combat Socialism from the standpoint of their special class interest these opponents—the parties which particularly call themselves “bourgeois” or “peasant”—admit indirectly the validity of all the essentials of socialist thought. For if it is only possible to argue against the socialist programme that it endangers the particular interests of one part of humanity, one has really affirmed Socialism. If one complains that the system of economic and social organization which is based on private property in the means of production does not sufficiently consider the interests of the community, that it serves only the purposes of single strata, and that it limits productivity; and if therefore one demands with the supporters of the various “social-political” and “social-reform” movements, state interference in all fields of economic life, then one has fundamentally accepted the principle of the socialist programme. Or again, if one can only argue against socialism that the imperfections of human nature make its realization impossible, or that it is inexpedient under existing economic conditions to proceed at once to socialization, then one merely confesses that one has capitulated to socialist ideas. The nationalist, too, affirms socialism, and objects only to its Internationalism. He wishes to combine Socialism with the ideas of Imperialism and the struggle against foreign nations. He is a national, not an international socialist; but he, also, approves of the essential principles of Socialism.
