Handling satisfactorily ICT ethics issues in the design as well as in the use of systems, demands continuous adjustment to relevant values. In privacy, robotics and sustainability, this can be achieved through the development of personal thinking skills and the establishment and running of suitable group processes. In ethical decision making it is important to make a distinction between thinking as a process, and value-content as the result of this process. By focusing on the process, i.e. philosophizing, the philosophical method of deliberative thinking, we can construct and apply tools to support ethical decision making during the development and the use of ICT systems.
