Cette thèse a pour objectif d’établir certains principes d’une potentielle théorisation de l’écriture biographiques. En liant des exemples prosaïques du XIXe siècle à certaines bases théoriques du XXIe siècle, il est question d’explorer les récurrences qui ont contribué à faire de certaines biographies des succès ou des échecs. En tant que biographe, essayiste et critique, Giles Lytton Strachey (1880-1932) est un sujet d’étude idéal qui permet d’analyser la relation entre le biographe, le biographié et le lecteur. Puis, selon le schéma structurel de la métahistoire proposé par Hayden White, il est possible d’émettre l’hypothèse que la biographie peut être un genre à part entière autant du point de vue de la forme que du fond. / The objective of this thesis attempts to illustrate a series of principles which could potentially lead to a theorisation of biographical writing. By exposing prosaic literary examples of the XIX century and certain theoretical bases of the XXI century, it is possible to depict recurrences that have contributed to the success or failure of various biographical works. Giles Lytton Strachey (1880-1932) as a biographer, essayist and critic appears to be the ideal subject that enables one to analyse the relationship between biographers, biographees and readers. Furthermore, the structural scheme of metahistory, as suggested by Hayden White, brings us one step closer to the assumption that biography can stand as a full-fledged genre both in terms of form and substance.

Denna uppsats undersöker hur samma historiska händelse kan ha olika betydelser i film. Idag är människor mer benägna att se en film om en historisk händelse än att läsa en historiebok, och detta innebär att vi måste lära oss att förstå de konventioner som används för att placera historia på film. Historiefilmen kan sägas besitta en palimpsestisk historiskt medvetenhet där lager av fakta och myt smälter samman, hellre än att skiljas åt. Men för att en historisk händelse ska passa in i filmens tidsram måste den bearbetas och detta resulterar i att vissa människor, händelser och rörelser prioriteras, medan andra utesluts. Därför undersöker denna uppsats vad som lagts till / uteslutits och effekterna på sammanhanget och trovärdighet, hur filmen hävdar sin autenticitet, och hur upphovsmannen påverkar trovärdigheten. Analysresultaten av två filmer om den kubanska revolutionen, visar att beroende på vilken del av den historisk händelsen som skildras, skapar filmerna helt olika berättelser med olika budskap. Medan filmen Che-Argentinaren (2008) fungerar som en hyllning av gerillanledaren Che Guevara som Kubas frälsare, visar en vänsterideologi och uttrycker USA förakt, skildrar däremot den andra filmen The Lost City (2005) revolutionens baksida. Den visar en högerideologi, familjevärderingar och USA som frihetens och drömmarnas land. Båda filmerna använder sig av liknande stilistiska strategier för att uppnå illusionen av autenticitet, och filmernas upphovsmän påverkar filmernas trovärdighet i olika grad. Vad jag i uppsatsen till sist menar är att historiefilmen inte bör tas som sanning, utan har en viktig roll som intresseväckare, som förhoppningsvis leder till att åskådaren blir intresserad av att söka sig mer kunskap. / This paper examines how the same historical event can have different meanings in films. Today people are more likely to watch a film about a historical event than to read a history book, and this means that we must learn and understand the conventions used to place history on film. The history film can be said to possess a palimpsetic historical consciousness in which layers of fact and myth come together rather than be separated. But for a historical event to fit within the film's time frame, it must be processed and this results in that certain people, events and movements are given priority, while others are excluded. Therefore, this paper studies what has been added/excluded and the effects on the context and credibility,how the film claims its authenticity, and how the author/filmmakers affects the credibility. The results of the analysis of two films about the Cuban revolution, shows that depending on which part of the historical event depicted, the films create entirely different stories with very different message. While the film Che-Part One (2008) serves as a celebration of the guerrilla fighter Che Guevara as Cuba's savior, according to a leftist ideology and the film is expressing U.S. disdain, the other film The Lost City (2005) however, portrays the revolutions backside, it shows a right-wing ideology, family values and the U.S. as the land of freedom and dreams. Both films use similar stylistic strategies to achieve illusion of authenticity, and the films' creators affect the films credibility in different amounts. What I finally conclude, is that the history film should not be considered as truth, but serve to arouse interest, which will hopefully lead the spectator to seek more knowledge about the historical event.

La tesi è stata intitolata “Change the System From Within”. La participatory democracy e le riforme istituzionali negli Stati Uniti degli anni Sessanta e si compone di cinque capitoli. Nel primo capitolo si riprende l’idea di participatory democracy emersa in seno alla New Left e ai movimenti sociali dei lunghi anni Sessanta. In questo contesto il concetto di participatory democracy assunse due principali accezioni: da una parte rappresentava la rivendicazione politica di un maggior coinvolgimento attivo della cittadinanza nelle politiche - locali, statali e federali - frutto della crisi di legittimità che la democrazia americana stava attraversando in quegli anni; dall’altra, il concetto venne adottato come principio organizzativo all’interno dei gruppi stessi di attivisti, con la funzione di prefigurare quelle riforme politico-istituzionali cui gli stessi militanti aspiravano. Dalla stessa temperie di contestazione sorse del resto anche la critica che alcuni studiosi mossero alla teoria liberale pluralista e alla sua esemplificazione nella coeva democrazia americana. Nel primo capitolo si mostra proprio come da quelle rielaborazioni critiche degli anni Sessanta emerse anche il primo modello di participatory democracy in seno alla teoria politica, sviluppato pienamente negli anni Settanta e Ottanta da Carole Pateman, Crawford B. Macpherson e Benjamin Barber. Questa parte del lavoro di tesi si propone quindi di accostare alle pratiche partecipative introdotte dai movimenti anche la ricostruzione dello sviluppo graduale di una teoria politica della participatory democracy. Tale riflessione è completata da un’analisi storica di ampio raggio, necessaria a meglio contestualizzare il fenomeno e ad includere le nuove richieste democratiche nell’ambito di una tradizione democratico-rappresentativa già dotata di istituti partecipativi di democrazia diretta. Chiarito il quadro storico-politico degli anni Sessanta, il secondo capitolo analizza la ricezione dell’idea di participatory democracy nelle politiche federali. A questo proposito si illustra come il principio di citizen participation fosse stato recepito già con la War on Poverty promossa da Lindon B. Johnson alla metà degli anni Sessanta e fu mantenuto, con esiti istituzionali differenti, almeno fino alla fine della presidenza Carter. Si dimostra inoltre che, malgrado il dettato legislativo federale fosse spesso approssimativo sulle modalità operative, quel principio ebbe in realtà un notevole impatto sulle relazioni intergovernative. Tale principio favorì ad esempio l’intraprendenza di molti amministratori locali nel promuovere il decentramento amministrativo e politico su base di quartiere. Nel terzo capitolo l’analisi affronta le principali trasformazioni in senso partecipativo avvenute nei sistemi di governo statali e locali negli anni Settanta, mettendole in relazione anche alle dinamiche intergovernative di più lungo periodo. Il capitolo è strutturato in modo tale da evidenziare il tendenziale recupero e rafforzamento di istituti già esistenti, come l’initiative, i public hearing e gli school district come strumenti di rivendicazione del community control in alcune città di grandi dimensioni. Mentre il secondo e terzo capitolo tendono a osservare le riforme istituzionali degli anni Settanta in senso partecipativo in seno al governo federale, statale e locale, i due successivi capitoli mirano ad osservare l’impatto della participatory democracy nel confronto tra attivismo militante e pratiche amministrative tradizionali degli anni Settanta. Il quarto capitolo è infatti dedicato all’ingresso della nuova generazione di politici progressisti nelle amministrazioni locali e statali fra la fine degli anni Sessanta e la prima metà degli anni Settanta. Per analizzarlo si è deciso di analizzare come principale caso di studio la Conference on Alternative State and Local Policy (CASLP), una organizzazione e forum nazionale che mirava proprio ad unire alle istanze dei progressisti una expertise di governo. Nell’ambito della CASLP, la cosiddetta Coalizione progressista di Berkeley, CA, fornì un caso esemplare di strategia di confronto con le istituzioni locali e per questo il capitolo le dedica una attenta disanima. La pluriennale esperienza di azione collettiva dei progressisti di Berkeley nell’arena istituzionale è infatti rilevante sia per l’innovazione nella strategia istituzionale, sia per attestare una evoluzione dell’idea di participatory democracy nel tempo. Il quinto capitolo ricostruisce ed analizza la carriera politica di Tom Hayden negli anni in cui passò dall’attivismo alla politica istituzionale, con la campagna elettorale per diventare Senatore della California in Congresso (1975-1976) e la successiva Campaign for Economic Democracy (1976-1982), confermando la spiccata propensione del leader all’innovazione istituzionale in senso partecipativo. In particolare, nella campagna elettorale per il Senato del Congresso del 1976 Hayden riuscì a implementare forme di decision-making partecipato in seno allo staff. Nella gestione del personale cercò inoltre di favorire l’empowerment di volontari e cittadini senza perdere di vista i requisiti essenziali per la sopravvivenza della campagna: fundraising e propaganda. In linea con la sua battaglia contro le distorsioni economiche del big business, scelse di non accettare fondi da corporation e banche e riuscì nell’intento di essere sostenuto per gran parte da small donors. Hayden dunque introdusse pratiche di participatory democracy in seno alla campagna elettorale e continuò a rivendicare la sua fiducia nella forza dei movimenti grass-roots. L’analisi storica, ad ogni modo, evidenzia anche le criticità che derivavano dall’uso di pratiche partecipative nella governance della campagna elettorale. Atttraverso l’analisi teorica e politico-istituzionale della democrazia partecipativa americana fra gli anni Sessanta e Settanta su vari livelli istituzionali (federale, statale e locale), questo progetto di ricerca tenta quindi di colmare un vuoto storiografico e, al tempo stesso intende contribuire alla definizione storico-istituzionale della participatory democracy in seno alla democrazia rappresentativa degli Stati Uniti. Infine, la presente ricerca mira a inserirsi nel dibattito pubblico contemporaneo sulla participatory democracy, offrendo una visione storico-istituzionale importante per meglio comprendere il fenomeno e che, finora, non ha ricevuto l’attenzione che meriterebbe. / Chapter 1 retrieves the idea of participatory democracy stemmed from the Long 1960s New Left and the following social movements. Indeed, the concept of participatory democracy mainly acquired two slightly different shapes in that historical framework. From one hand, it meant the broad political call for common citizens’ greater involvement in the policy-making - at the local, state and federal level. That request was in fact a reply to the ongoing crisis of the American democracy, in terms of political legitimacy and social representation of minorities and poor people. In the other hand, participatory democracy represented the organizing principle adopted by most of the grass-roots groups of that period, with a clear prefigurative function. Indeed, making the activist groups’ inner decision-making participatory was a way for the collectives to anticipate the institutional changes they aspired to. In the meantime, because of the same disaffection against the raising social and political inequalities, some political science scholars elaborated a critique to the pluralist version of the liberal democracy - then the most praised one, as well as credited as it was embodied in the American democracy. Those 1960s critiques were eventually used to conceive the first political theory of participatory democracy in the 1970s and 1980s, as Chapter 1 shows. The participatory democracy’s canon was in fact mostly developed by Carole Pateman, Crawford B. Macpherson and Benjamin Barber. Beside the intellectual history of participatory democracy from 1960s to 1980s, Chapter 1 allows to contextualize ideas and practices of common citizens’ participation into the wider history of the American Political Development. According to that, chapter 1 also provides a detailed analysis of the participatory political institutions that were traditionally part of the United States representative democracy. Chapter 2 verifies whether the 1960s idea of participatory democracy actually affected the federal public policies of the late 1960s and 1970s. Indeed the principle of “citizen participation” was introduced in some of the War on Poverty legislations, promoted by Lyndon B. Johnson since the mid-1960s. Although the heterogeneous institutional effects, that principle was maintained in some grant-in-aid projects until the end of the Carter administration, through the Nixon and Ford administrations. Therefore, the political meanings assumed by the idea of “citizen participation” and its institutional consequences from 1964 to 1980 are carefully analyzed in chapter 2. Moreover, chapter 2 shows that the principle of citizen participation had such a strong impact on the intergovernmental relations. It thus brought forward, for instance, the local public officers’ entrepreneurship towards the local devolution, shifting the administrative and political power base from the center to the neighborhood. Chapter 3 deals with the 1970s main institutional reforms aimed at introducing the common citizens’ participation in the government decision-making at the state and local levels. Those reforms are deeply related to some long-lasting intergovernmental dynamics and this relationship is also argued. The same chapter’s lay-out is vowed to underline the 1970s general trend of retrieval and enhancing of traditional institutions, such as the initiative (direct democracy), the public hearings and the school districts. The school board was indeed reevaluated and reshaped as a means of community control in the biggest cities. As chapters 2 and 3 aim at exploring the implementation of participatory reforms in the federal, state and local level of government, chapters 4 and 5 aim at inquiring the participatory democracy’s impact on the 1970s boundary of polity - the space where activism meets political institutions. Chapter 4 inquires the new generations of progressive politicians entering the local and state administrations from the late 1960s to the mid-1970s. To frame that national phenomenon, the historical analysis use the Conference of Alternative States and Local Policies (CASLP) as a case study. CASLP was indeed a national organization born in 1975 to give voice to the progressive public officers around the country and allowed them sharing their government experiences for a more effective institutional impact. Inside CASLP, the progressive coalition of Berkeley, CA (called Berkeley Citizens’ Action, BCA) was especially spotted for its exemplary strategy to confront local political institutions. The 1970s BCA’s political actions are thus specifically analyzed. In fact, the institutional approach of the Berkeley progressive coalition resulted to be innovative in terms of strategy as well as successful in introducing new forms of participatory democracy into the local government, assessing the 1970s evolution of the participatory democracy political theory and practices. Chapter 5 retraces the political career of the former New Left leader Tom Hayden during the years of turning from activism to institutional politics. Especially, the analysis focuses on the 1975-1976 U.S. Senate Campaign and the following Campaign for Economic Democracy (CED), a coalition project and organization led by Hayden with the goal of mobilizing activists and public officers around the issues of economic justice, environmental and economic public policies (1976-1982). That period - just before Hayden was elected representative at the California Legislature in 1982 - is thus analyzed as a testing ground to verify his long-lasting commitment towards participatory democracy. The historical and political analysis, based on original archival findings, confirms Hayden’s inclination for institutional innovation in the participatory realm. In particular, during the 1975-1976 electoral campaign for the U.S. Senate in California Hayden introduced participatory forms of decision-making involving staff people, volunteers and supporting grass-roots groups. Moreover, that campaign’s staff and people management was conceived in order to directly empower citizens and volunteers, without losing track of the campaigning basic requirements (e. g. fundraising and propaganda). As he stood against big business and economic inequalities, he chose to reject fundings from corporations and banks. Therefore his electoral campaign was mostly sustained by small donors. Hayden successfully made the campaigning more open, accountable and participatory and kept on sponsoring his trust in community organizing and grass-roots social movements even in his following political endeavour, CED. Eventually, the investigation casts lights on the strengths, as well as the critical issues, produced by the Hayden’s participatory governance of campaigning. By the means of analysing the intellectual history and the institutional implementation of participatory democracy during late 1960s-1970s United States, this research project firstly aims at making up the lack of historiography about the topic. In the second stance, grounding the institutional and political history of participatory democracy in the United States representative democracy - where the concept was born - this research project intends to provide a first genealogy of the participatory democracy’s institutional implementation. In this sense, the research projects wants also to contribute to the contemporary debate on the participatory democracy. It is indeed a compelling and popular issue in many worldwide political arenas, but it is still rarely defined by its historical and institutional terms.
