Orientador: Carlos Erivany Fantinati / Banca: João Luís Cardoso Tápias Ceccantini / Banca: Maria Lídia Lichtscheidl Maretti / Banca: Alice Áurea Penteado Martha / Banca: José Batista de Sales / Resumo: Este trabalho estuda seis obras de Monteiro Lobato consideradas de cunho educativo, buscando identificar a tensão entre o pedagógico e o estético e levando em conta o fato de que o momento histórico e social brasileiro favorecia a publicação de tais obras. Nesse aspecto, convém ressaltar a correspondência de fatores entre o momento de publicação dessas obras (1933-1937) e o momento em que surgiu a Literatura Infantil no século XVIII. Tal fato explica a influência de uma corrente de pensamento denominada Iluminismo ou Ilustração, que proporcionaria condições para que esse gênero circulasse na sociedade da época. Da mesma forma, nas obras de Lobato em questão, pode-se detectar a presença das mesmas idéias, tendo sempre em vista a busca da divulgação do saber e o progresso. Para este fim, utilizou-se, como ponto de apoio teórico, a tese de Rouanet (1987) de que as idéias do Iluminismo não se extinguiram no século XVIII, mas ainda estão presentes neste momento sob nova perspectiva. Tomouse também, como ponto de apoio, a indicação de Antonio Candido (1993) de que a obra literária apresenta um diálogo entre autor/obra/público, refletindo as estruturas sociais existentes em seu momento de produção. Na análise, foram enfocados os elementos mais importantes das obras, a saber: o narrador, as personagens infantis, as personagens adultas e os conteúdos escolares evocados. Os resultados obtidos indicam a presença dos ideais iluministas na medida em que as obras prezam pela união entre o útil e o agradável, como forma de equilibrar a tensão entre estético e pedagógico. / Abstract: This work studies six books of Monteiro Lobato, considered of an educative approach, trying to identify the tension between the pedagogic and the esthetic, having in consideration the fact that the historic and social moment of Brazil was favor to the publication of such a work. In this manner, is valuable to emphasize the connection of factors between the publication of such works (1993-1937) and the moment when appears Children Literature in the 18th century. This explain the influence of the way of thinking named Enlightenment or Illustration, that provide conditions to the circulation of such kind in that time. In the same manner, in the books of Lobato in question, is detectable the presence of the same ideas, having always in sight the desire to spread knowledge and progress. To this end, was used as point of theory support, the idea of Rouanet (1987) that the ideas of Enlightenment didn't ended in the 18th Century but still are presents under new perspective. Having also as a theory support the indication by Antonio Candido (1993) that the literary work presents a dialogue between the author, the work and the public, reflecting the social structures existing in the time of production. In the analysis, were in focus the most important elements of the work that is: the narrator, the children persons, the adult persons and the school material evoked. The results indicate the presence of the enlightenment's ideas because de books value the alliance between the utility and the pleasant, how to equilibrate the tension between the pedagogic and the esthetic. / Doutor

Orientador: Osmir Batista de Oliveira Júnior / Banca: Rosane de Fátima Zanirato Lizarelli / Banca: Cristina Kurachi / Resumo: A estabilidade de cor de duas resinas compostas diferentes frente ao envelhecimento físico/químico foi avaliada, em função dos seguintes fatores: composição e tipo de luz fotoativadora. Para isso, foram confeccionados 15 corpos-de-prova para a resina Filtek Supreme, e 15 corpos-de-prova para a resina 4 Seasons. Ambos os materiais foram polimerizados com três fontes de luz diferentes: uma luz halógena, e dois sistemas LEDs. Tais corpos-de-prova foram submetidos ao envelhecimento artificial, inicialmente através de imersão em água destilada por 24 horas, e após esse período foram expostos à luz ultravioleta por 24 horas, em associação à imersão em água destilada. As mensurações de cor foram realizadas com o auxílio de um espectrofotômetro de reflectância e tais mensurações, através de uma fórmula matemática apropriada, permitiu que o total de alteração de cor (?E) fosse avaliado, para todas as variações, nos seguintes períodos de tempo: após imersão em água destilada (T1-T2) e após exposição à luz ultravioleta (T1-T3). Os resultados foram submetidos à Análise de Variância, sendo que através da mesma foi possível observar que: a resina composta Filtek Supreme apresentou média de alteração de cor (DE) estatisticamente maior que a resina composta 4 Seasons; o tipo de luz fotopolimerizadora (LED ou halógena) não determinou diferenças estatísticas na propriedade de estabilidade de cor para os materiais estudados. Ambos os materiais sofreram alteração de cor significativa, tanto estatística quanto visualmente, após o processo de envelhecimento artificial. / Abstract: Color stability of two different composite resins after artificial aging was evaluated, against the following factors: composition and type of photo-activating light. Therefore, 15 specimens from Filtek Supreme composite resin and 15 specimens from 4 Seasons composite resin were prepared. Both materials were polymerized with three different light devices: one halogen light and two LEDs systems. These specimens were submitted to artificial aging, initially through immersion in distilled water for 24 hours and then through exposure to ultraviolet light for 24 hours, in association with immersion in distilled water. The color mensurations were accomplished by a reflectance spectrophotometer and these mensurations, through a proper mathematical formula, allowed that the total color alteration (?E) was evaluated, for each variation, at the following period of time: after distilled water immersion (T1-T2), and after ultraviolet light exposure (T1-T3). These results were analyzed by a analysis of variance, and through this analysis it was possible to notice that: Filtek Supreme composite resin presented color alteration average (?E) statistically higher than the 4 Seasons composite resin average; the type of photopolymerization light (LED or halogen) did not define any statistical differences on color stability for both studied materials. Both materials underwent significant color alteration, both statistical and visually alterations, after the artificial aging process. / Mestre

Os objetivos deste trabalho foram avaliar a estabilidade de cor e capacidade de mascaramento até 1.000.000 de ciclos termomecânicos das facetas de cerâmica híbrida e cerâmica reforçada com dissilicato de lítio processadas pelo método de fresagem CAD/CAM; verificar a influência da cor do cimento em relação a cor final das facetas e a correspondência entre as pastas try-in; e as respectivas cores dos cimentos. Foram confeccionadas 60 facetas cerâmicas, pelo método de fresagem, que foram cimentadas com cimento fotopolimerizável (Variolink Esthetic LC), seguindo as orientações dos fabricantes, em réplicas de incisivos centrais escurecidos (C4) e não escurecidos (A2) e distribuídas nos grupos experimentais (n=10) DA2N, DC4N, DC4L, HA2N, HC4N, HC4L de acordo com o tipo de cerâmica dissilicato de lítio (D) e híbrida (H), cor do substrato A2 e C4, e cor do cimento neutral (N) e ligth (L). As leituras com espectrofotômetro foram realizadas previamente à cimentação das facetas, facetas + pastas Try-In, imediatamente após cimentação da faceta, após 48h, 72h e após ciclos termomecânicos (250.000, 500.000, 750.000 e 1.000.000) em máquina de ciclagem. Os dados foram analisados pelo teste ANOVA-2 medidas repetidas e teste Tukey (5%). Observou-se que ambas as cerâmicas apresentaram estabilidade de cor e capacidade de mascaramento, pois apesar de ocorrer diferença estatística em alguns grupos, todos os valores de E apresentaram-se abaixo de 1,7, ou seja, não são perceptíveis. Da mesma forma, verificou-se que a cor dos cimentos (neutral e light) não influenciou na cor final das restaurações, pois não houve diferença estatística significante comparando-se os grupos DC4N e DC4L como também entre HC4N e HC4L. Correlacionando-se as pastas try-in com as cores dos respectivos cimentos todos os valores obtidos para E ficaram abaixo de 3,3 que é considerado o limite como perceptível por observadores não treinados. Concluiu-se que as facetas de cerâmica híbrida e dissilicato de lítio apresentam muito boa estabilidade de cor ao longo do tempo e capacidade de mascaramento. Assim como, as diferentes cores de cimento não influenciam a cor final das facetas e as pastas try-in apresentam fidelidade em relação às respectivas cores dos cimentos. / The objectives of this work were to evaluate the color stability and masking ability up to 1,000,000 thermomechanical cycles of hybrid and reinforced with lithium disilicate ceramics processed by the CAD/CAM method; to verify the influence of cement color in relation to the final color of the veneers; and the correspondence between try-in and respective colors of the cements. 60 ceramic veneers were prepared using the milling method, which were cemented by light-curing cement (Variolink Esthetic LC) according to the manufacturer\'s instructions on replicates of darkened (C4) and nondarkened central incisors (A2) and distributed in the experimental groups (n=10) - DA2N, DC4N (D), DC4L, HA2N, HC4N, HC4L according to ceramic - lithium disilicate (D) and hybrid (H), substrate color - A2 and C4, and cement color - neutral (N) and ligth (L). The spectrophotometer measurements were performed prior to veneers cementation, veneers + try-In, immediately after cementing, after 48h, 72h and after thermomechanical cycles (250,000, 500,000, 750,000 and 1,000,000) in a cycling machine. Data were analyzed by ANOVA-2 repeated measures and Tukey test (5%). It was observed that both ceramics presented color stability and masking ability, because although there was a statistical difference in some groups, all values of E were below 1.7, ie, they are not perceptible. Likewise, it was found that the color of the cements (neutral and light) did not influence the final color of the restorations, since there was no significant statistical difference comparing the groups DC4N and DC4L as well as between HC4N and HC4L. By correlating the tryin with the colors of the respective cements all values obtained for E were below 3.3 which is considered the limit as perceived by untrained observers. It was concluded that hybrid ceramics and lithium disilicate veneers exhibit very good color stability over time and masking ability. As well as, the different cement colors do not influence the final color of the veneers and try-in pastes show similarity to the respective colors of the cements.

A ausência ou perda da papila interdental cria deficiência estética, problemas fonéticos, impactação alimentar e gera muita expectativa ao paciente. Até o momento, o tratamento da ausência ou perda da papila interdental tem sido mal sucedido e não há estudos que indiquem que a regeneração da papila é um resultado previsível. O objetivo deste estudo foi avaliar a efetividade da injeção de gel de ácido hialurônico de origem não animal na redução ou eliminação da deficiência de papila entre dentes naturais comparativamente ao tratamento por meio de enxerto de tecido conjuntivo subepitelial. Foram avaliados neste estudo 20 sítios de 6 pacientes de ambos os sexos, com idade variável de 29 a 62 anos, apresentando deficiência de papila entre dentes naturais, na região anterior superior, em pelo menos dois dentes. Os 20 sítios tratados foram aleatoriamente divididos em dois grupos, de acordo com o tratamento para correção da deficiência de papila por meio de enxerto de tecido conjuntivo subepitelial (grupo controle) ou por meio de injeção de gel de ácido hialurônico (grupo teste). Um examinador único, calibrado, avaliou a distância da ponta da papila ao ponto de contato com auxílio de sonda periodontal milimetrada antes e aos 1, 3 e 6 meses após o tratamento. Além disso, foram investigados, nos sítios tratados, as medidas de profundidade de sondagem, nível de inserção, índice de sangramento do sulco, índice de placa, distância do ponto de contato à crista óssea alveolar, distância da ponta da papila à crista óssea alveolar e largura da papila. Os resultados demonstraram que aos 6 meses de pósoperatório o percentual de mudança na altura da papila foi maior no grupo teste (14,94% ± 21,35%) do que no grupo controle (-1,39% ± 31,46%), entretanto sem diferenças significantes entre os grupos (p> 0.05). Não houve variação estatisticamente significante na largura da papila antes e aos 4 meses após o tratamento nos grupos teste (p= 0.09) e controle (p= 0.16), assim como não houve variação significativa na distância entre a ponta da papila e a crista óssea alveolar. Houve melhora significativa do Índice de Estética Rosa (IER) observado aos 6 meses de acompanhamento em comparação com a condição inicial no grupo teste (p= 0.0078; Wilcoxon), enquanto que não houve mudança significativa no IER observado no grupo controle aos 6 meses de acompanhamento (p= 0.35). Os resultados obtidos permitiram concluir que o tratamento da deficiência de papila por meio de injeção de gel de ácido hialurônico promove melhora da deficiência de papila, similar aos resultados obtidos com o tratamento por meio de enxerto de tecido conjuntivo subepitelial, porém com melhora estética significativa relacionada especialmente às características de cor e textura do tecido relativamente aos tecidos moles adjacentes. / The absence or loss of interdental papilla creates an esthetic deficiency, phonetic problems and food impaction and generates a lot of expectation for the patient. Until now, the treatment for absence or loss of interdental papilla is unsuccessful e and there are no researches that show that the papilla regeneration is a predictable outcome. The aim of this study was to evaluate the effectivity of a non-animal originated hyaluronic acid injection in the reduction or elimination of papilla deficiency between natural teeth in comparison to a sub epithelial connective tissue graft treatment. The analysis was made on 20 sites in 6 patients, both genders, 29 - 62 years, showing deficiency in the papilla between natural teeth in the upper anterior region in at least two teeth. The 20 sites treated were randomly divided into two groups, according to the treatment by subepithelial connective tissue graft (control group) or by hyaluronic acid injection (test group). A single calibrated examiner evaluated the distance between the tip of the papilla to the contact point using a graduated periodontal probe before the treatment and 1, 3 and 6 months after it. Besides, it were investigated probing pocket depth, clinical attachment level, gingival bleeding index, plaque index, distance from papilla to alveolar crest, distance from contact point to alveolar crest and width of the papilla. The results showed that 6 months after the procedure, the percentage of change in the papilla level was higher in the test group (14,94% ± 21,35%) than in the control group (-1,39% ± 31,46%), though not statistically significant (p>0.05). There was no significant difference variation in the width of the papilla before and 4 months after the treatment in test group (p=0.09) and control group (p=0.16), and there was no significant difference variation in the distance between the tip of the papilla and the alveolar bone crest. There was significant improvement of the Pink Esthetic Score (PES) after 6 months in comparison to the initial condition in test group (p=0.0078; Wilcoxon), while there was no significant difference in the PES in control group 6 months after treatment (p=0.35). The results allow to conclude that the treatment for of the papilla deficiency using hyaluronic acid injection promotes improvement, similar to the results of the sub epithelial connective tissue graft treatment, but with significant esthetic improvement related specially to the color and texture characteristics of the adjacent soft tissues.

Orientador: Lauro Cardoso Villela / Banca: Maria Auxiliadora Junho de Araújo / Banca: Rolf Rode / Resumo: O objetivo deste estudo foi desenvolver em silicona, uma escala de tonalidades de pele humana. Foram confeccionados vinte e sete corpos de prova em silicona acética (Silastic 732 RTV), pigmentados com óxidos de ferro e dióxido de titânio. A quantidade da silicona acética manteve-se constante (duas gramas) em todos os corpos de prova, e os pigmentos foram misturados a ela, em várias proporções, até a obtenção das vinte e sete diferentes tonalidades. A partir da comparação dos corpos de prova, com a cor da pele de quarenta e um indivíduos, foram selecionados os cinco corpos de prova com as tonalidades que mais se igualavam à cor da pele dos mesmos, compondo assim, um guia de tonalidades. Variações nas quantidades dos pigmentos utilizados permitiram a obtenção de novas tonalidades. Com a metodologia empregada, foi possível desenvolver uma escala de tonalidades de pele que poderá facilitar a definição do tom da pele do paciente, quando da confecção de próteses faciais em silicona, permitindo economia de tempo e de material no momento da seleção da cor / Abstract: The objective of this paper was to develop one silicone guide for human skin shades. Twenty-seven samples were manufactured in acetic silicone rubber (Silastic 732 RTV) pigmented with iron oxides and titanium dioxide. The qua ntity of acetic silicone rubber used in each specimen was kept constant (two grams) and the pigments were mixed to it in several proportions until the obtention of twenty-seven different shades. Through the comparison of the color of each sample with the skin color of forty-one individuals were selected the five samples which shades best matched the individuals' skin colar, determining in this way, a shade guide. Variations in the quantity of pigments used permited the obtention of new shades. With the employed methodology it was possible to develop a shade guide that can facilitate the definition of the patient's skin color when making facial prostheses in silicone allowing economy of time and material at the moment of color selection / Mestre

Esta dissertação inicia-se com uma pesquisa sobre o conceito de modernidade, e suas denominações: Modernidade/Pós-modernidade; a seguir, recorremos à Arte Moderna, para depois adentrarmos a Estética literária no projeto da modernidade, foco da pesquisa e, para tanto, apresentamos valores literários de alguns escritores-críticos modernos. Assim, expostas as idéias em diálogo na modernidade, procedemos a formatação de um paradigma a que chamamos de paradigma Projeto da Modernidade. Discorremos sobre a crítica literária atual, e as autoras pesquisadas: a portuguesa Alice Vieira e a brasileira Lygia Bojunga Nunes. Selecionamos e realizamos um estudo paradigmático analíticocrítico em duas obras literárias para crianças e jovens, a saber: Flor de Mel de Alice Vieira e Corda bamba de Lygia Bojunga Nunes. Fizemos uma aproximação do paradigma PM formatado para este estudo ao final de cada análise, assim como uma aproximação entre Flor de Mel e Corda bamba. Dessa forma, pudemos constatar o quanto a qualidade estética do texto narrativo; desconsiderando se a obra pode ser endereçada ao receptor adulto ou criança, ou seja, se é chamada de literatura para crianças e jovens, ou não; comprova a estética literária da modernidade a que nos propusemos investigar neste estudo. / This thesis starts by researching the concept of Modernity and its denominations. Modernity/Post-modernity; then, we approach Modern Art, and, later, we enter the literary esthetics in the project of Modernity, which is the focus of the research and, for that purpose, we present literary values of some modern critic-writers. So, once the ideas in Modernity dialog have been exposed, we proceed to the formatting of a paradigm which we call Project of Modernity Paradigm. We go about the current literary criticism, and the researched writers: Portuguese Alice Vieira and Brazilian Lygia Bojunga Nunes. We selected and performed an analytical-critical paradigm study in two literary works for children and youngsters, namely: Flor de Mel, by Alice Vieira and Corda bamba, by Lygia Bojunga Nunes. We did an approximation of the PM paradigm, for this study, in the end of each analysis, as well as an approximation between Flor de Mel and Corda bamba, so that we could find how much the esthetic quality of the narrative text, disregarding whether the work can be addressed to the adult or children receptors, in other words, if the literature mentioned is for children and youngsters, or not, does evidence the literary esthetics of Modernity which we proposed to investigate in this study.

H.-G. Gadamer prirovnáva skúsenosť umeleckého diela k hre, symbolu a slávnosti a v kontexte symbolu ďalej k náboženskému rituálu - Večeri Pánovej v poňatí Martina Luthera. Luther symbolické chápanie Kristovej prítomnosti vo Večeri Pánovej odmietal, a tak vyvstáva otázka, prečo Gadamer toto prirovnanie použil, v čom spočíva podobnosť jednotlivých skúseností a kde sú jej hranice. Táto práca sa snaží na otázku zodpovedať pomocou analýzy Gadamerovej filozofie umenia, Lutherovej sakramentologie a následného porovnania týchto problémov vo vybraných oblastiach. Dochádza k záverom, že podobnosť spočíva v štruktúre umeleckého diela a sviatosti. V oboch prípadoch sa nejedná o vzťah odkazovania, ale o sprítomňovanie významu v prvom prípade a Krista v druhom prípade. Rozdiely sa ukazujú za prvé v povahe sprítomňovaného - v umeleckom diele ide o duchovný význam, vo Večeri Pánovej podľa Luthera o skutočné, tj. zmyslové telo Krista. Za druhé význam umeleckého diela vzniká až s ním samým, kým obsah sviatosti je už vždy dopredu daný. Za tretie, v skúsenosti umeleckého diela je divácky subjekt jeho aktívnou súčasťou, kým v sviatosti prijíma dar.

Indiana University-Purdue University Indianapolis (IUPUI), Indiana University School of Dentistry / Background: With the emerging of digital dentistry, IPS e.max® CAD lithium disilicate (LD) glass-ceramic material has become one of the most popular esthetic restorative materials in digital assisted dental esthetic restoration. The mechanical and optical properties of this material have been investigated in several studies. However, there is a lack of information and consensus regarding the optical properties of IPS e.max® LD glass-ceramic materials. Objectives: 1) To investigate the optical properties as translucency parameters (TP), Contrast ratio (CR), light transmissions (Lt) and color changes (CC) between high-translucent (HT) and low-translucent (LT) IPS e.max® CAD LD glass-ceramic materials with different crystalline phases and thickness in different firing stages. 2) To investigate the optical properties as TP, CR, Lt and CC of each translucent (HT and LT) IPS e.max® CAD LD glass-ceramic materials with different crystalline phases and thickness in different firing stages. 3) To determine the mathematical relationships of thicknesses of IPS e.max® CAD LD glass-ceramics materials with TP and Lt. Materials and methods: The total of 120 of shade A2 IPS max CAD samples (HT and LT) were prepared into square shape (15.25 mm X 15.25 mm) and were divided into two main groups according to the material translucency (HT and LT) (n=60). Each main group was further divided into 5 sub-groups according to the thickness (1.00, 1.25, 1.5, 1.75, and 2.00 mm) (n=12). Each thickness group was assigned into three groups based on different crystallization (firing) temperatures (750, 820 °C in single stage heating schedule with 1 second and 10 second holding times, respectively, and 840 °C with two-stage heating schedule (RECOM) (820°C, 840 °C with 10 second and 7 min holding time, respectively) as recommended by manufacturer (n=4). CIEL*a*b*, TP, CR, and Lt were measured and calculated for all samples. Statistical analysis: The effects of the test results were evaluated using 3-way ANOVA with factors for Translucency (HT and LT), Firing Temperature (750, 850, and RECOM) and Thickness (1, 1.25, 1.5, 1.75, and 2), as well as all two-way and three-way interactions among the factors. Pair-wise comparisons were made using Least Significant Differences to control the overall significance level at 5%. Results: The mean irradiance and TP for both HT and LT decrease as the thickness of the samples increases from 1 to 2mm with significant difference between the thickness groups within each material translucency groups (HT and LT) and between both HT and LT. The coefficients of absorption (c) of the two materials were calculated. The effective incidence irradiance when material thickness approaches zero (Ie) was also calculated. There is an unexpected spectral peak shift as the thickness of the samples increases. There is no statistically significant difference in Ie at 750˚C and 820 ˚C between the HT and LT. However, there is a statistically significant higher Ie in HT at the recommended firing temperature as expected. Coefficients of translucency parameter (p) of the materials in various firing temperature were defined and the TP of the material as the thickness approaches zero were calculated (TP0). The TP of the materials is directly correlated to the mean irradiance passing through the samples. There is no statistically significant difference in the TP0 and Ie of the HT and LT groups at the recommended firing temperature. Conclusion: In this project we developed modified Beer-Lambert law to describe the parameters governing the effect of thickness on light transmission in dental ceramic material. We also applied the same equation to describe the translucency parameter. The parameters defined in these equations allow us to compare the optical property of dental ceramic material independent of the thickness of the samples.

The purpose of this study was to determine the influence of dentofacial appearance on perceived social attributes of college-aged adult males and females as judged by their peers. Specifically, the objective was to determine if ideal smile esthetics positively influenced this age group’s perception of opposite-sex peers based on ratings of the following psychosocial characteristics: attractiveness, desire to spend time with, desire to date, and desire for a long-term relationship. Evaluators were shown digital photographs of subjects with ideal and nonideal smiles and asked to rate those 4 attributes using a visual analogue scale (VAS). The subjects’ photographs with ideal smile esthetics were consistently rated higher on average than the same subjects’ photographs with nonideal smile esthetics. The differences in ratings between ideal and nonideal smile images were significant for all 4 psychosocial judgments (P <.0001). These differences ranged in magnitude depending on the sex and race of the evaluator and subject.

Apocryphal Theatre: Practising Philosophies is a practice-based research project that consists of examples of my theatre practice (as research) and a written thesis. In this thesis, I argue that theatre can be seen to be an act of philosophy, by tessellating Maurice Merleau-Ponty's definition of philosophy as consisting of relearning to look at the world and Gilles Deleuze and Felix Guattari's proposition that philosophy is the creation of concepts, and pointing to post-WWII theatre artists whose work both fulfill this definition of philosophy and have informed Apocryphal Theatre's work. Included is an analysis of interviews with three contemporary theatre artists, Richard Foreman, Chris Goode and Ivana Muller, which explore their relationship with philosophical ideas in their work and how that informs their ability to create acts of philosophy. In practice, the research questions that underpin Apocryphal Theatre's research in labs, rehearsals and performance, are philosophical and create the potential for collective acts of philosophy. Apocryphal's practice as research as manifest in its ongoing lab and in the two productions included as part of this thesis, The Jesus Guy and Besides, you lose your soul or The History of Western Civilisation, will be analysed for the historical and philosophical bases of the primary concepts we have created through our research and the tools with which we embody them. The concepts and tools, which are used to address the research questions, are the witness, the grid, cutting up, levels of address and levels of presence. This thesis concludes that theatre and philosophy whilst separate disciplines can overlap in such a way that acts of philosophy can occur in the theatre, and that Apocryphal's theatrical project, which is collaborative, polyvocal and in performance invites the audience to be active witness/participants in the creation of the event, can be viewed as a collective act of philosophy.
