[3] Despite being greatly influenced by the logical positivists and critical of unempirical speculation, an aspect common to all of Kaila's work was in strive for a holistic, almost pantheistic understanding of things.
During the last years of his life he attempted to construct a theory of everything in Terminalkausalität Als Die Grundlage Eines Unitarischen Naturbegriffs, but this, what was meant to be the first installment in a more extensive study, was not met with much enthusiasm outside of Finland.
Though he withdrew his support of the National Socialists before the end of the Second World War, he wrote about the differences between "western" and "eastern" thought and claimed that the homogeneity of the people was a necessity for a functioning democracy.
[2] After the war his close friendships with Edwin Linkomies and Veikko Antero Koskenniemi put a political shadow even over Kaila.
[4] Kaila's most famous pupil was Georg Henrik von Wright, who was the successor of Ludwig Wittgenstein at the University of Cambridge.
