converted to critique the present and propose alternative futures. Just as inequality, injustice and exploitation are all too often established and perpetuated by means of design, there is also an ongoing claim to critically uncover, dismantle and reconfigure these conditions through or with design: through or with critical design practices, methods, histories, manifestos or attitudes. Critical practice, in the words of design researcher Ramia Mazé, is often regarded as «a kind of ‹criticism from within› design -that is based on and carried out by design means, by designers and by means of their own practical and operational modes» (Mazé 2016: para. 1). Cause, criticism and measures appear to be closely linked here. However, it remains a virulent question as to how the language, logics and materialities of design, the epistemological baggage of the discipline, and the methods, approaches and strategies within design practice itself can be thought of and implemented as a mode and vehicle of critique. The answers and positions in this regard are constantly shifting and require disentangling and rethinking. In this process, design is, more or less obviously, also changing its roles, scope and influence in ever more comprehensive social, cultural, political and professional contexts, practices, systems and discourses. «Critical by Design?» is a question to which there is no unambiguous answer, but many different, even contradictory suggestions.This anthology brings together interdisciplinary perspectives and new impulses for the discussion and advancement of criticality in design. The contributions offer investigations into design as a mode of critique from various backgrounds and positionings towards the discipline, from design studies and history to design practice and education as well as philosophy, art history and theory, and informatics. The interrogative notion of the title «Critical by Design?» carries throughout the book. It is a genuine questioning, neither neglecting nor readily affirmative of the critical potentials of design. It is a careful, but by no means exhaustive attempt to consider in more detail from which positionalities and framings notions of criticality in design can be legitimately and productively conceptualized, how specifically critique has to be fashioned and articulated under the conditions and modes of operation of design, and how our understandings and vocabularies of critique and critical practices can be diversified and expanded. As such, the contributions in this volume are not primarily trying to provide best practices of critical design approaches, but are sharing this questioning and interrogative attitude, each in their own way trying to open up new spaces, vocabularies or frames of reference to think about critique and criticality in design.Therefore, in the very beginning, it is necessary to turn the gaze of critique inward, as self-critique. Although we have striven to create or in front of oneself), design's promise to open up futures is very aptly expressed. In the act of ...
