Popper's short essay about the rationality principle has been the target of many criticisms which have raised serious doubts about its consistency. How could the well-known promoter of falsificationism suggest that we not reject a principle that he himself describes as false? Nonetheless, the essay can be read in a way that makes it appear much more consistent. Better sense can be made of Popper's own examples (the flustered driver, the pedestrian, etc.), by taking seriously his view that the rationality (...) principle might be "approximately true" and falsified only in very rare cases, while also giving proper attention to his four rather elliptical arguments.

The paper proposes a distinction between ethical problems internal to the practice of a discipline and ethical problems external to it. It argues that ethical problems encountered in architecture are typically of the former kind, in contrast, for example, to bioethical problems. From this point of view, it discusses the state of other arts and surveys various 19th and 20th century positions concerning ethics in architecture. It illustrates that, where architecture is concerned, ethics is closely related to aesthetics and frequently (...) tied to a philosophy of history, a point which is explained with the help of the above-mentioned distinction.
