At the end of his career he is also known for his critical opposition to the theory of relativity. He published several papers in which he tried to argue against the theory of relativity mostly from a philosophical standpoint. In his private life he was known as an outspoken fennoman, that is, a proponent of adopting the Finnish language as language of state and culture instead of the Swedish one that had been mainly used up to that point in the young republic of Finland.
