In this classic work, Herbert Marcuse takes as his starting point Freud's statement that civilization is based on the permanent subjugation of the human instincts, his reconstruction of the prehistory of mankind - to an interpretation of the basic trends of western civilization, stressing the philosophical and sociological implications.

New computer systems of discovery create a research program for logic and philosophy of science. These systems consist of inference rules and control knowledge that guide the discovery process. Their paths of discovery are influenced by the available data and the discovery steps coincide with the justification of results. The discovery process can be described in terms of fundamental concepts of artificial intelligence such as heuristic search, and can also be interpreted in terms of logic. The traditional distinction that places (...) studies of scientific discovery outside the philosophy of science, in psychology, sociology, or history, is no longer valid in view of the existence of computer systems of discovery. It becomes both reasonable and attractive to study the schemes of discovery in the same way as the criteria of justification were studied: empirically as facts, and logically as norms. (shrink)

F. P. Ramsey pointed out in Theories that the observational content of a theory expressed partly in non-observational terms is retained in the sentence resulting from existentially generalizing the conjunction of all sentences of the theory with respect to all nonobservational terms. Such terms are thus avoidable in principle, but only at the cost of forming a single "monolithic" sentence. This paper suggests that communication may be thought of as occurring not only by sentence but by clause, a sentential formula (...) closed except for a special kind of variable. Understanding such clauses requires incorporating them within the scope of one's own Ramsey sentence. Many concepts of deductive and inductive logic carry over without great change. But the concepts of truth and designation are extendible to clauses only in the sense that assertions involving them must, to be understood, in turn be construed as clauses and incorporated into the Ramsey sentence. The behavior of these extended concepts of truth and designation suggests an explication of coherence truth within a correspondence-truth framework. (shrink)

The commonly accepted interpretations ofFermat's method of extreme values tell us that this is a curious method, based on an approximate equality and burdened with several contradictions withinFermat's writings. In this article, both a philological approach taking into account that there is only one manuscript written inFermat's own handwriting and a mathematical approach taking into account that brilliant mathematicians usually are not so very confused when talking about their own central mathematical ideas are combined. A new hypothesis is put forward (...) which renders the mathematics clear and coherent and which does not need the assumption thatFermat was confused. Probably a number of words have been added byCarcavy in two ofFermat's papers. (shrink)

Over the past decade numerous philosophers have devoted considerable effort to explicating and defending the claim that narrative can be a satisfactory form of explanation. Much of this interest in narrative has taken the form of a reaction against the covering-law model of explanation-particularly against the claim that that model is applicable to history and to what W. B. Gallie has called “the genetic sciences.” What has been lacking from most of this discussion of narrative is any very clear indication (...) of just what narrative is or any extended attempt to delineate its logical features. The philosophical yield of introducing the concept “narrative” into discussions of explanation has frequently appeared to be very small.In a recent paper Michael Ruse has argued that the logical structure of explanations relating to the theory of evolution can be examined more helpfully by using the covering-law model than by using a narrative model of explanation.

Der Psychoanalytiker Herbert Stein nimmt die Herausgabe der Heraklit-Vorlesungen Heideggers zum Anlaß und Ausgangspunkt, die Stellung Freuds und der Psychoanalyse im Rahmen der Geschichte abendländisch-europäischen Denkens neu zu untersuchen. Freud steht mit seinem "Glauben" an "unseren Gott Logos" unwissentlich in der Nachfolge Heraklits. Hinsichtlich dieses seines damit ausgedrückten, wenn auch gemäßigten Wissenschaftsglaubens ist unsere Zeit eher pessimistischer als Freud. Unsere Logik der Wissenschaft und Technik scheint mit "Notwendigkeit" in ihre Krise zu geraten . Für künftige Lösungen der Krise muß (...) das Denken sich seinen Ursprüngen zuwenden. (shrink)

In connection with the special theory of relativity, Einstein made use of a now familiar thought experiment1 involving two lightning flashes, a railway train, and an embankment. Whether he used it merely to help explain the theory to others or whether it played a role in the theory's very generation as well is perhaps a matter of conjecture. However, physicist Richard Feynman, for one, believes that Einstein first conceived his theories in the visualizations of thought experiments and developed their mathematical (...) formulations afterwards. According to a recent magazine essay, ‘Einstein came to an understanding about relativity by imagining people going up in elevators and beaming light back and forth between rocket ships. (shrink)

The VI. International Leibniz Congress was held at the University of Hannover, 18-23 July 1994. There were more than 300 participants from 26 countries. About 160 papers were given to the Congress. The opening lecture was given by Professor Nicholas Rescher. The Congress offered the opportunity of meeting Leibniz scholars from all over the world. The participants received the first volume of the papers. A second volume will appear soon. There are plans to give this second volume as a “Mitgliedsgabe” (...) to the members of the Leibniz-Gesellschaft. (shrink)
