Download E-books A Philosophy of Technology: From Technical Artefacts to Sociotechnical Systems (Synthesis Lectures on Engineers, Technology, and Society) PDF

By Maarten Franssen

In A Philosophy of know-how: From Technical Artefacts to Sociotechnical structures, know-how is analysed from a sequence of other views. The research begins through focussing at the so much tangible items of know-how, known as technical artefacts, after which builds step-wise in the direction of contemplating these artefacts inside their context of use, and finally as embedded in encompassing sociotechnical structures that still comprise people as operators and social ideas like laws. Philosophical characterisations are given of technical artefacts, their context of use and of sociotechnical structures. Analyses are provided of the way technical artefacts are designed in engineering and what different types of technological wisdom is thinking about engineering. And the difficulty is taken into account how engineers and others can or can't effect the improvement of expertise. those characterisations are complemented by way of moral analyses of the ethical prestige of technical artefacts and the probabilities and impossibilities for engineers to steer this prestige whilst designing artefacts and the sociotechnical platforms within which artefacts are embedded. The working instance within the booklet is aviation, the place aeroplanes are examples of technical artefacts and the area aviation process is an instance of a sociotechnical process. concerns relating to the layout of quiet aeroplane engines and the reasons of aviation injuries are analysed for illustrating the ethical prestige of designing, and the function of engineers therein. desk of Contents: Technical Artefacts / Technical Designing / Ethics and Designing / Technological wisdom / Sociotechnical platforms / The function of Social elements in Technological improvement / Ethics and accidental effects of expertise
