Design Science? A Debate
There is a debate about the rationale of design: is design a science or not, in other words does it produce knowledge of its own that can be justified and how?
Why is it a Necessary Question?
It is a tricky question primarily because in the history of philosophy, there has been very little interest about the conceptive activities within science. However, science is not only about justifying observations, it is also about changing paradigms, finding new questions, building new tools and concepts. In a word, sciences have to be conceptive too.
Contemporary Sciences
Today some philosophers such as Anne-Françoise Schmid, look at contemporary sciences and demonstrate that they not only look at natural (or social) phenomena and build some knowledge about these phenomena, they also build artificial things and produce knowledge about these artificial things: engineering sciences are at the heart of this question but also more broadly design. Therefore, we need an epistemology of these conceptive sciences.
Definition of Epistemology
Epistemology is at the crossroad between sciences and philosophy: it considers how different sciences build their object of research.
“Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one’s own mind? Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry”.
