This interesting essay argues that there is only one Wittgenstein, not two: one Wittgenstein who used two alternative modes of expression, two alternative languages for one framework; moreover, these two options are not sequential, but co-exist and are complementary. The very possibility of two such complementary modes of expression is itself a significant metaphilosophical matter.
