Johannes Rehmke (1 February 1848 – 23 December 1930) was a German philosopher and since 1885 professor at Universität Greifswald, later also provost of this university.
He offered sharp criticisms of Kant's approach to epistemology.
In his article The Conquest of Subjectivism, Paul Linke pointed out that it was Rehmke who first banned the words, 'subjective,' 'objective,' 'immanent,' and 'transcendent,' from his philosophical vocabulary.
He made a courageous break from subjectivism, which was the pervasive philosophical paradigm of the times, and also criticized phenomenalism.
