Taking into account the real historical development of Wittgenstein's writings, the author studies the development of his thought and investigates his view concerning the possible existence of a genuine machine intelligence. Topics include the logicist research program, Wittgenstein on inference, the limit of mathematical language, intuitionism and philosophy, Brouwer's impact on Wittgenstein, calculation and experiment, and the foundations of mathematics.
