"The completion of the socialist revolution within national limits is unthinkable."

“In Stalin each easily finds himself. But Stalin also finds in each one a small part of his own spirit. Stalin is the personification of the bureaucracy. That is the substance of his political personality.”

“The tacit assumption underlying the Lenin-Trotsky theory of dictatorship is this: that the socialist transformation is something for which a readymade formula lies completed in the pocket of the revolutionary party, which needs only to be carried out energetically in practice. This is, unfortunately or – perhaps fortunately – not the case.”
