Engineering deals with different problem situations than science, and theories in engineering are different to theories in science. So, the growth of knowledge in engineering is also different to that in science. Nonetheless, methodological issues in engineering epistemology can be explored by adapting frameworks already established in the philosophy of science. In this paper I use critical rationalism and Popper’s three worlds framework to investigate error elimination and the growth of knowledge in engineering. I discuss engineering failure arising from the (...) falsification of engineering theories, and present taxonomies of the sources of falsification and responses to falsification in engineering. From this I discuss contexts of research and design in engineering, ad hoc rescue of engineering theories, and engineering assurance. (shrink)

We examine the intentional processes that correspond to conceptualizations of activities performed by subjects with the intention of achieving an objective. Taking as its basis a general framework of intentional processes, two types of such process are considered: epistemic ones, aimed at acquiring knowledge about something, and poietic ones, aimed at bringing about something. The “something” is understood as anything that the processes can pertain to: a physical, mental or abstract object, a phenomenon, a state of affairs, etc. The generic (...) features of such processes are discussed, with focus on: features that are common for epistemic and poietic intentional processes as well as on features that differentiate them, the dynamic and static features of the processes, and on issues involved in controlling the progression of the processes towards intended objectives. The latter issue is the essential part of our considerations, the two former establish the necessary conceptual framework. The presented analysis aims at shedding light on these aspects of human intentional activities which can be considered virtually independent of any specific area of human intentional activity, be it natural sciences, humanities or technology.
