Ten brilliant essays on logic appear in this collection, the work of one of the world’s best-known authorities on logic. In these thought-provoking arguments and meditations, Nobel Prize winner Bertrand Russell challenges the romantic mysticism of the 19th century, positing instead his theory of logical atomism. These essays are categorized by Russell as "entirely popular" and "somewhat more technical." The former include the well-known title essay plus "A Free Man’s Worship" and "The Place of Science in a Liberal Education"; the (...) latter comprise "On the Notion of Cause" and "Knowledge by Acquaintance and Knowledge by Description," along with other essays written in the cogent and witty style for which their author is justly renowned.

This paper is both a slice of history, a warning and a congratulation. The history is about how the Russell papers found their way to a steel-town in Canada and how it came about that they have gradually been published. The warning is that it is extremely difficult to conduct such an enterprise on a co-operative basis, which may help to explain why so many enterprises of this kind have issued in failure. The congratulations are for those who have edited (...) volumes of very different kinds, as a result of Russell's versatility, in a manner which throws new light on his intellectual history. All of this had to be described in a very schematic way. But it will, I hope, lead readers to the volumes themselves. Only there will they find the answer to the exercise I set towards the end of the article. (shrink)

It is shown how frege's problematic connection between truth-Value and "bedeutung" (of a sentence) becomes more plausible when set against the background of german language and philosophy, Especially by comparing frege's position with the value-Theoretical school of neo-Kantianism (w windelband).

Many historians of analytic philosophy consider the early philosophy of Moore, Russell and Wittgenstein as much more neo-Hegelian as once believed. At the same time, the authors who closely investigate Green, Bradley and Bosanquet find out that these have little in common with Hegel. The thesis advanced in this chapter is that what the British (ill-named) neo-Hegelians brought to the early analytic philosophers were, above all, some ideas of Lotze, not of Hegel. This is true regarding: (i) Lotze’s logical approach (...) to practically all philosophical problems; (ii) his treating of the concepts relation, structure (constructions) and order; (iii) the discussion of the concepts of states of affairs, multiple theory of judgment, general logical form; (iv) some common themes like panpsychism and contemplating the world sub specie aeternitatis.

State of affairs (Sachverhalt) is one of the few terms in philosophy, which only came into use for the first time in the twentieth century, mainly via the works of Husserl and Wittgenstein. This makes the task of finding out who introduced this concept into philosophy, and in exactly what sense, of considerable interest. Our thesis is that Lotze introduced the term in 1874 in the sense of the objective content of judgments, which is ipso facto the minimal structured ontological (...) unit. We would argue against authors such as Michael Dummett and Barry Smith, who have tried to prove that Lotze's theory of judgment, and so of states of affairs, was ad-vanced in the wake of psychologism.

Lotze’s "Microcosm" was published in three volumes, in 1856, 1858 and 1864, respectively. It was soon one of the most widely read philosophy books of the time. It was translated into French and Russian immediately, into English in 1885/87, and into Italian in 1911/16. The book saw six editions in Germany alone by 1923.

Russell’s second philosophy of time (1899–1913), which will be the subject of this paper, is of special interest for two reasons. (1) It was basic to his New Philosophy, later called the “philosophy of logical atomism”. In fact, this philosophy didn’t initially emerge in the period of 1914– 1919, as many interpreters (e.g. A. J. Ayer) suggest, but with the introduction of Russell’s second philosophy of time (and space). The importance of Russell’s second philosophy of time for his early and (...) middle philosophy can be seen from the fact that it survived the dramatic changes in his philosophy of August–December 1900, and of July 1905. There is of course no surprise about this point: it served as their fundament. (2) Russell’s second philosophy of time is a locus classicus of all so called B-theories of time which define it in terms of the relations of before, after and simultaneous between events or moments. 20th century philosophy; absolute theory of time; theory of time; order; relation; relationist theory of time; B-series.

Two concepts of utmost importance for the analytic philosophy of the twentieth century, “sense-data” and “knowledge by acquaintance”, were introduced by Bertrand Russell under the influence of two idealist philosophers: F. H. Bradley and Alexius Meinong. This paper traces the exact history of their introduction. We shall see that between 1896 and 1898, Russell had a fully-elaborated theory of “sense-data”, which he abandoned after his analytic turn of the summer of 1898. Furthermore, following a subsequent turn of August 1900—-after he (...) became acquainted with the works of Peano and later of Frege—-Russell gradually developed another theory of sense-data. With the collaboration of G. E. Moore, Russell reintroduced the term “sense-data” in 1911. Concomitantly with this move, Russell introduced the epistemological term “knowledge by acquaintance”, which came to designate the grasping of sense-data and universals. (shrink)
