Ole Thyssen (born November 3, 1944) is a Danish philosopher and sociologist, and Professor at the Copenhagen Business School.
He started out as a marxist philosopher, writing about psychoanalysis, Karl Marx and Wilhelm Reich.
Beginning in the mid-1980s, however, his focus has gradually shifted towards the sociological systems theory of Niklas Luhmann, and much less political themes.
In the mid-1990s he was appointed Professor at the Copenhagen Business School, where he was also one of the initiators of the combination MA degree in Business Administration and Philosophy in 1995.
Most are based on Luhmann's systems theory.
