Thinkers for Architects – serie

Bruno Latour is one of the leading figures in Social Sciences today, but his contributions are also widely recognised in the arts. His theories ‘flourished’ in the 1980s in the aftermath of the structuralism wave and generated new concepts and methodologies for the understanding of the social. In the past decade, Latour and his Actor-Network Theory (ANT) have gained popularity among researchers in the field of architecture.Latour for Architects is the first introduction to the key concepts and ideas of Bruno Latour that are relevant to architects. First, the book discusses critically how specific methods and insights from his philosophy can inspire new thinking in architecture and design pedagogy. Second, it explores examples from architectural practice and urban design, and reviews recent attempts to extend the methods of ANT into the fields of architectural and urban studies. Third, the book advocates an ANT-inspired approach to architecture, and examines how its methodological insights can trace new research avenues in the field, reflecting meticulously on its epistemological offerings.Drawing on many lively examples from the world of architectural practice, the book makes a compelling argument about the agency of architectural design and the role architects can play in re-ordering the world we live in. Following Latour’s philosophy offers a new way to handle all the objects of human and nonhuman collective life, to re-examine the role of matter in design practice, and to redefine the forms of social, political and ethical associations that bind us together in cities.

The work of Gilles Deleuze and Felix Guattari has been inspirational for architects and architectural theorists in recent years. It has influenced the design work of architects as diverse as Greg Lynn and David Chipperfield, and is regularly cited by avant-gardist architects and by students, but usually without being well understood. The first collaboration between Deleuze and Guattari was Anti-Oedipus: Capitalism and Schizophrenia, which was taken up as a manifesto for the post-structuralist life, and was associated with the spirit of the student revolts of 1968. Their ideas promote creativity and innovation, and their work is wide-ranging, complex and endlessly stimulating. They range across politics, psychoanalysis, physics, art and literature, changing preconceptions along the way. Deleuze & Guattari for Architects is a perfect introduction for students of architecture in design studio at all levels, students of architecture pursuing undergraduate and postgraduate courses in architectural theory, academics and interested architectural practitioners.

Specifically for architects, the third title in the Thinkers for Architects series examines the relevance of Luce Irigaray’s work for architecture. Eight thematic chapters explore the bodily, spatio-temporal, political and cultural value of her ideas for making, discussing and experiencing architecture. In particular, each chapter makes accessible Irigaray’s ideas about feminine and masculine spaces with reference to her key texts. Irigaray’s theory of ‘sexed subjects’ is explained in order to show how sexuality informs the different ways in which men and women construct and inhabit architecture. In addition, her ideas about architectural forms of organization between people, exterior and interior spaces, touch and vision, philosophy and psychoanalysis are explored. The book also suggests ways in which these strategies can enable architectural designers and theorists to create ethical architectures for the user and his or her physical and psychological needs.Concisely written, this book introduces Irigaray’s work to practitioners, academics, undergraduate and postgraduate students in architectural design and architectural history and theory, helping them to understand the value of cross- and inter-disciplinary modes of architectural practice.

The work of Homi K. Bhabha has permeated into numerous publications which use postcolonial discourse as a means to analyze architectural practices in previously colonized contexts, particularly in Africa, Asia, the Middle-East, South-East Asia and, Latin America. Bhabha's use of the concept of ‘space’ has made his work highly appealing to architects and architectural theorists. This introductory book, specifically for architects, focuses on Bhabha’s seminal book The Location of Culture and reveals how his work contributes to architectural theory and the study of contemporary architectures in general, not only in colonial and postcolonial contexts.

The philosophy of Maurice Merleau-Ponty (1908–1961) has influenced the design work of architects as diverse as Steven Holl and Peter Zumthor, as well as informing renowned schools of architectural theory, notably those around Dalibor Vesely at Cambridge, Kenneth Frampton, David Leatherbarrow and Alberto Pérez-Gómez in North America and Juhani Pallasmaa in Finland. Merleau-Ponty suggested that the value of people’s experience of the world gained through their immediate bodily engagement with it remains greater than the value of understanding gleaned through abstract mathematical, scientific or technological systems. This book summarizes what Merleau-Ponty’s philosophy has to offer specifically for architects. It locates architectural thinking in the context of his work, placing it in relation to themes such as space, movement, materiality and creativity, introduces key texts, helps decode difficult terms and provides quick reference for further reading.

Pierre Bourdieu is arguably one of the twentieth century’s greatest socio-philosophical thinkers and his writings have much to offer anyone interested in the ways that people value, consume and produce architecture. Bourdieu spent much of his life attempting to understand cultural consumption and production through detailed empirical research that included studies of dwellings, art, museums, photography and aesthetics. This book introduces the architectural reader to Bourdieu’s key writings on culture and outlines the ways in which they offer powerful practical tools and novel conceptual frameworks for understanding architectural value, taste, and practice.

Marginalized due to the deployment of both a highly specialized jargon and a novel stylistic approach meant to upset established norms and conventions, Baudrillard's thought has suffered from the lack of an accessible, consistent and comprehensive exposition able to make it relevant to diverse contemporary disciplines. As a result, its impact on architecture has always been confined to academia. By presenting an introductory but in-depth formalization of Baudrillard's interest in architecture and related fields, this book makes intelligible his philosophical premises thus showing, through the prism of architecture, their relevance and persuasiveness today. Key concepts such as the object system, the code, simulation, hyperreality and precession, to name a few, are addressed in the light of the specially reconceptualized key construct of ambience, thus emphasizing how the mutual concerns of architecture, urban studies and cultural studies provide a fertile ground for debate.Such an approach, which focuses on the contradictions inherent in contemporary society from the vantage point of Baudrillard's original involvement in architectural analysis, philosophy and criticism, is one which students, practitioners and scholars alike from as diverse disciplines as architecture, interior design and urban studies – but also fine art, anthropology, sociology, economics, human geography, social psychology and cultural studies to start with – will benefit from immensely.

Providing a concise and accessible introduction to the work of the celebrated twentieth century German philosopher, Hans-Georg Gadamer, this book focuses on the aspects of Gadamer’s philosophy that have been the most influential among architects, educators in architecture, and architectural theorists. Gadamer’s philosophy of art gives a special place to the activity of "play" as it occurs in artistic creation. His reflections on meaning and symbolism in art draw upon his teacher, Martin Heidegger, while moving Heidegger’s thought in new directions. His theory of interpretation, or "philosophical hermeneutics," offers profound ways to understand the influence of the past upon the present and to appropriate cultural history in ever new forms. For architects, architectural theorists, architectural historians, and students in these fields, Gadamer’s thought opens a world of possibilities for understanding how building today can be rich with human meaning, relating to architecture’s history in ways that do not merely repeat nor repudiate that history.In addition, Gadamer’s sensitivity to the importance of practical thinking – to the way that theory arises out of practice – gives his thought a remarkable usefulness in the everyday work of professional life.

Looking afresh at the implications of Jacques Derrida’s thinking for architecture, this book simplifies his ideas in a clear, concise way. Derrida‘s treatment of key philosophical texts has been labelled as "deconstruction," a term that resonates with architecture. Although his main focus is language, his thinking has been applied by architectural theorists widely.As well as a review of Derrida’s interaction with architecture, this book is also a careful consideration of the implications of his thinking, particularly on the way architecture is practiced.

American philosopher Nelson Goodman (1906-1998) was one of the foremost analytical thinkers of the twentieth century, with groundbreaking contributions in the fields of logic, philosophy of science, epistemology, and aesthetics. This book is an introduction to the aspects of Goodman’s philosophy which have been the most influential among architects and architectural theorists.Goodman specifically discussed architecture in his major work on aesthetics, The Languages of Art: An Approach to a Theory of Symbols (1968), and in two essays "How Buildings Mean" (1985), and "On Capturing Cities" (1991). His main philosophical notions in Ways of Worldmaking (1978) also apply well to architecture. Goodman’s thought is particularly attractive because of its constructive aspect: there is not a given and immutable world, but both knowledge and reality are constantly built and rebuilt. Whereas other theories, such as deconstruction, implicitly entail an undoing of modern precepts, Goodman’s conception of world-making offers a positive, constructive way to understand how a plural reality is made and remade.Goodman’s approach to architecture is not only relevant thinking in providing new insights to understanding the built environment, but serves also as an illustration of analytical thinking in architecture. This book shows that the methods, concepts, and ways of arguing characteristic of analytical philosophy are helpful tools to examine buildings in a novel and fruitful way and they will certainly enhance the architect’s critical skills when designing and thinking about architecture.

While the work of Henri Lefebvre has become better known in the English-speaking world since the 1991 translation of his 1974 masterpiece, The Production of Space, his influence on the actual production of architecture and the city has been less pronounced. Although now widely read in schools of architecture, planning and urban design, Lefebvre’s message for practice remains elusive; inevitably so because the entry of his work into the Anglosphere has come with repression of the two most challenging aspects of his thinking: romanticism and Utopia, which simultaneously confront modernity while being progressive.Contemporary discomfort with romanticism and Utopia arguably obstructs the shift of Lefebvre’s thinking from being objects of theoretical interest into positions of actually influencing practices. Attempting to understand and act upon architecture and the city with Lefebvre but without Utopia and romanticism risks muting the impact of his ideas. Although Utopia may seem to have no place in the present, Lefebvre reveals this as little more than a self-serving affirmation that ‘there is no alternative’ to social and political detachment. Demanding the impossible may end in failure but as Lefebvre shows us, doing so is the first step towards other possibilities. To think with Lefebvre is to think about Utopia, doing so makes contact with what is most enduring about his project for the city and its inhabitants, and with what is most radical about it as well. Lefebvre for Architects offers a concise account of the relevance of Henri Lefebvre’s writing for the theory and practice of architecture, planning and urban design. This book is accessible for students and practitioners who wish to fully engage with the design possibilities offered by Lefebvre’s philosophy.

From the mid-1960s onwards Michel Foucault has had a significant impact on diverse aspects of culture, knowledge and arts including architecture and its critical discourse. The implications for architecture have been wide-ranging. His archaeological and genealogical approaches to knowledge have transformed architectural history and theory, while his attitude to arts and aesthetics led to a renewed focus on the avant-garde.Prepared by an architect, this book offers an excellent entry point into the remarkable work of Michel Foucault, and provides a focused introduction suitable for architects, urban designers, and students of architecture. Foucault’s crucial juxtaposition of space, knowledge and power has unlocked novel spatial possibilities for thinking about design in architecture and urbanism. While the philosopher's ultimate attention on the issues of body and sexuality has defined our understanding of the possibilities and limits of human condition and its relation to architecture.The book concentrates on a number of historical and theoretical issues often addressed by Foucault that have been grouped under the themes of archaeology, enclosure, bodies, spatiality and aesthetics in order to examine and demonstrate their relevancy for architectural knowledge, its history and its practice.

This book introduces architects to a philosopher, Immanuel Kant, whose work was constantly informed by a concern for the world as an evolving whole. According to Kant, in this interconnected and dynamic world, humans should act as mutually dependent and responsible subjects. Given his future-oriented and ethico-politically concerned thinking, Kant is a thinker who clearly speaks to architects. This introduction demonstrates how his ideas bear pertinently and creatively upon the world in which we live now and for which we should care thoughtfully. Kant grounded his enlightened vision of philosophy’s mission using an architectural metaphor: of the modest 'dwelling-house'. Far from constructing speculative 'castles in the sky' or vertiginous 'towers which reach to the heavens', he tells us that his humble aim is rather to build a 'secure home for ourselves', one which appropriately corresponds at once to the limited material resources available on our planet, and to our need for firm and solid principles to live by. This book also explores Kant's notions of cosmopolitics, which attempts to think politics from a global perspective by taking into account the geographical fact that the earth is a sphere with limited land mass and natural resources. Given the urgent topicality of sustainable development, these Kantian texts are of particular interest for architects of today.Students of architecture, who are necessarily trained in negotiating between theory and practice, gain much from considering Kant, whose critical project also consisted of testing and exploring the viability of ideas, so as to ascertain to what extent, and crucially, how ideas can have a constructive effect on the whole world, and on us as active agents therein.
