"Mazzini despised the compromises of the "whigs" and would have no truck with the diplomacy of a Cavour. Yet he came to admit that the programme of insurrections upon which he built his faith implied the sacrifice of a generation. Disdaining immediate objects, reaching far into the future—working for all or nothing—he pointed to the reward that would be enjoyed not by his contemporaries, not by their children perhaps, but at least (let us say) by their grandchildren. Unfortunately, at this very point—in the passage from one generation to another—history seems in a particular way to intervene and to deflect the results of human endeavour; so that we may doubt whether this attempt to overreach Time itself is the proper kind of far-sightedness to have in politics. Apart from new factors that may change the course of the story, there is a process which may give efficacy to the ideas of a Mazzini precisely in so far as these ideas can be made to serve the cause of power; and it is not entirely irrelevant that though Mazzini was no Fascist he did attack the individualism of 1789, and he taught young men to sink themselves—to intoxicate themselves—in the Organic People. One of the things that may happen therefore in the transition to a new generation is the possibility that Mazzini's whole doctrine—and his glorification of nationality—when mixed with a little earth and entangled in a world of tricks and chances, will form but the raw material for the next Mussolini that may arise."
