This is a comprehensive guide to the basic movements we can observe in the sky.

Included are the sun's pattern of the day and of the year, the moon's various periods, nodes and eclipses, as well as the planets' apparent movement and loops, conjunctions and transits. The appendix contains tables of periods and rhythms, and a guide to important occurrences to the year 2010.

Joachim Schulte's introduction provides a distinctive and masterful account of the full range of Wittgenstein's thought. It is concise but not compressed, substantive but not overloaded with developmental or technical detail, informed by the latest scholarship but not pedantic.

In this book, translated from the German by the author, Joachim Schulte uses the discussions of psychological concepts in Wittgenstein's late manuscripts as a basis of reconstructing the central arguments and ideas developed by Wittgenstein during that period. This reconstruction yields valuable insights not only in the philosophy of psychology, but also in aesthetics and the theory of meaning.

Wittgenstein's last work, On Certainty, is widely regarded as his third masterpiece of philosophy and one of his most enigmatic writings. On Certainty explores the ways in which claims of indisputable knowledge are expressed, and how language forms the basis of such claims. On Certainty has largely been read as representing a break with Wittgenstein's previous thinking, but this study places these ideas firmly in the development of his thought since the 1930s. Wittgenstein on Certainty and Doubt illuminates Wittgenstein's examination of the logical features of epistemic terms-such as 'know', 'believe' and 'doubt'-and his interrogation of the foundations of human knowledge, the extent to which our knowledge is immune from doubt, and the conflicts between different articulations of knowledge.
