The domain of informatics, was initially development of computer-based information systems based on mathematical/logical perspective. In mid-1970s, some doctoral students stated that use of these systems should also be studied. Hence work content, work environment and power relations at the workplace should be studied. This cannot be done solely with mathematical/logical methods. Based on Ludwik Fleck's concepts of thought style and thought-collective, Kuhn's paradigm theory and Berger & Luckmann's knowledge sociology, some events taking place during the decade 1975-85 are analyzed and the concept of though tstruggle is introduced. My problem statement is:

1. How can the conceptual idea within the informatics in Sweden during the period 1970-1985 be understood?

2. Why did this happen just then?

3. How does it fit into the other changes in society?

The result is a description of the thought struggle, what triggered it and what it led to, and where the events have been placed within dimensions of time, positivism and philosophy.
