core77 on Tools of Design Representation
The inherent characteristics of the tool-in-hand (the TDR in use) can and does have an influence upon reflective practice. However, this tool-focused approach overlooks one important factor. As the German philosopher Martin Heidegger once said, 'A tool is only a tool insofar as it is used as such to achieve an expected goal'. That is, the designer brings his or her expertise, skills, knowledge and judgment to TDR choice and use (or lack thereof); their understanding of a tool's strengths and limitations, in terms of the requirements of design practice (or lack thereof), has clear implications for the extent to which the design tool influences the design practice.
I haven't come across that "A tool is only a tool..." quote before. The only link in Google is the blog post.
