Drawing on a range of philosophical texts, Andrej Radman brings together a collection of his essays, published over the last decade, to show that when a society manipulates its matter it is not a reflection of culture, it is culture. To speak of ecologies of architecture is to break with judgement for experience. As Gilles Deleuze put it in his book on Nietzsche, it is not about justification, 'but a different way of feeling: another sensibility'. If to think differently we have to feel differently, then the design of the built environment has no other purpose but to transform us. While engineering is solution-oriented, architecture stays with the problem so as to tease out a creative potential.
