Available for the first time in 20 years, here are two important works from the 1920s by the best-known representative of the Vienna Circle. In The Logical Structure of the World, Carnap adopts the position of "methodological solipsism" and shows that it is possible to describe the world from the immediate data of experience. In his Pseudoproblems in Philosophy, he asserts that many philosophical problems are meaningless.

This book is about scientific theories of a particular kind - theories of mathematical physics. Examples of such theories are classical and relativis tic particle mechanics, classical electrodynamics, classical thermodynamics, statistical mechanics, hydrodynamics, and quantum mechanics. Roughly, these are theories in which a certain mathematical structure is employed to make statements about some fragment of the world. Most of the book is simply an elaboration of this rough characterization of theories of mathematical physics. It is argued that each theory of mathematical physics has associated with it a certain characteristic mathematical struc ture. This structure may be used in a variety of ways to make empirical claims about putative applications of the theory. Typically - though not necessarily - the way this structure is used in making such claims requires that certain elements in the structure play essentially different roles. Some playa "theoretical" role; others playa "non-theoretical" role. For example, in classical particle mechanics, mass and force playa theoretical role while position plays a non-theoretical role. Some attention is given to showing how this distinction can be drawn and describing precisely the way in which the theoretical and non-theoretical elements function in the claims of the theory. An attempt is made to say, rather precisely, what a theory of mathematical physics is and how you tell one such theory from anothe- what the identity conditions for these theories are.

There are few more important philosophers at work today than John Searle, a creative and contentious thinker who has shaped the way we think about mind and language. Now he offers a profound understanding of how we create a social reality--a reality of money, property, governments, marriages, stock markets and cocktail parties. The paradox he addresses in Making the Social World is that these facts only exist because we think they exist and yet they have an objective existence. Continuing a line of investigation begun in his earlier book The Construction of Social Reality, Searle identifies the precise role of language in the creation of all "institutional facts." His aim is to show how mind, language and civilization are natural products of the basic facts of the physical world described by physics, chemistry and biology. Searle explains how a single linguistic operation, repeated over and over, is used to create and maintain the elaborate structures of human social institutions. These institutions serve to create and distribute power relations that are pervasive and often invisible. These power relations motivate human actions in a way that provides the glue that holds human civilization together. Searle then applies the account to show how it relates to human rationality, the freedom of the will, the nature of political power and the existence of universal human rights. In the course of his explication, he asks whether robots can have institutions, why the threat of force so often lies behind institutions, and he denies that there can be such a thing as a "state of nature" for language-using human beings.

First published in 1999, this is an interesting and significantly valuable example of how Hegel’s Logic can be applied to his own interpretation of his time to produce a contemporary Hegelian view of our world and its problems. The authors show that by the logic of the family, as conceived by Hegal, contemporary views about same sec and single parent families can be justified and defunded. The male-dominance and heterosexual orientation taken for granted by Hegal’s own world is not mandated by the Logic. I find their argument completely convincing. They demonstrate beyond dispute that Hegel’s speculative philosophy remains relevant for us, a very fruitful in its applications.

The only book to investigate the parallel between what happens at other times and what happens in other possible worlds.
