Tiedepolitiikkaa on hallinnut ajatus, että rahankäyttöä voidaan tehostaa ja tutkimuksen laatua parantaa kilpailuttamalla, arvioimalla ja keskittämällä rahoitus huippututkimukselle. Huippututkimuksen ajatellaan edellyttävän suuria tutkimusryhmiä. Lisäksi rahoitusta keskitetty yhä enemmän tieteidenvälisille hankkeille. Kirjoituksessa tarkastellaan näitä trendejä kriittisesti viimeaikaisen tieteentutkimuksen ja tieteenfilosofian parhaan tiedon valossa. Näyttää siltä, että suosittu politiikka ei johda toivottuihin lopputuloksiin.

The concept of truth and competing philosophical theories on what truth amounts to have an important place in contemporary philosophy. The aim of this chapter is to give a synopsis of different theories of truth and the particular philosophical issues related to the concept of truth. The literature on this topic is vast, and we must necessarily be rather selective and very brief about complex questions of interpretation of various philosophers. The focus of the chapter is mainly on selected systematic issues and the most influential and well-established philosophical theories and key concepts.

The new theory of reference has won popularity. However, a number of noted philosophers have also attempted to reply to the critical arguments of Kripke and others, and aimed to vindicate the description theory of reference. Such responses are often based on ingenious novel kinds of descriptions, such as rigidified descriptions, causal descriptions, and metalinguistic descriptions. This prolonged debate raises the doubt whether different parties really have any shared understanding of what the central question of the philosophical theory of reference is: what is the main question to which descriptivism and the causal-historical theory have presented competing answers. One aim of the paper is to clarify this issue. The most influential objections to the new theory of reference are critically reviewed. Special attention is also paid to certain important later advances in the new theory of reference, due to Devitt and others.

Yhteiskuntatieteiden ja humanististen tieteiden, tai lyhyemmin, ihmistieteiden, asema tieteiden joukossa on monien kiistojen kohteena. Ihmistieteiden ja luonnontieteiden välistä suhdetta koskevassa keskustelussa on perinteisesti ollut vastakkain kaksi kantaa: Toinen näkökanta on painottanut, että sama yleinen tieteellinen menetelmä soveltuu niin luontoon kuin ihmiseenkin ja että ollakseen tieteellisiä ihmistieteiden on täytettävä samat tieteellisyyden kriteerit kuin luonnontieteidenkin. Toinen on korostanut ihmistieteiden olemuksellista erilaisuutta luonnontieteisiin verrattuna, koska ne noudattavat erityistä ymmärtävää menetelmää.

Nykyaikaisen formaalisen logiikan kehityksen alkutaivalta leimasivat kunnianhimoiset tavoitteet ja vahva optimismi. Tavoitteena oli osoittaa koko matematiikalle ehdottoman varma perusta. Parhaimmillaan filosofian ongelmienkin uskottiin ratkeavan formaalisen logiikan avulla. Filosofisesti kuitenkin on mielenkiintoisinta, että nykyaikainen formaalinen logiikka on mahdollistanut formaalisen lähestymistavan rajoitusten kiistattoman ja matemaattisen täsmällisen osoittamisen. Tämäntyyppisillä tuloksilla on monia tärkeitä filosofisia seurauksia. Esittelen tässä artikkelissa tiettyjä keskeisiä tällaisia logiikan rajoittavia tuloksia.

Quine’s thesis of the indeterminacy of translation has puzzled the philosophical community for several decades. It is unquestionably among the best known and most disputed theses in contemporary philosophy. Quine’s classical argument for the indeterminacy thesis, in his seminal work Word and Object, has even been described by Putnam as “what may well be the most fascinating and the most discussed philosophical argument since Kant’s Transcendental Deduction of the Categories” (Putnam, 1975a: p. 159).

Here the relationship between understanding and knowledge of meaning is discussed from two different perspectives: that of Dummettian semantic anti-realism and that of the semantic externalism of Putnam and others. The question addressed is whether or not the truth of semantic externalism would undermine a central premise in one of Dummetts key arguments for anti-realism, insofar as Dummetts premise involves an assumption about the transparency of meaning and semantic externalism is often taken to undermine such transparency. Several notions of transparency and conveyability of meaning are distinguished and it is argued that, though the Dummettian argument for anti-realism presupposes only a weak connection between knowledge of meaning and understanding, even this much is not trivially true in light of semantic externalism, and that semantic externalism, if true, would thus represent a reason for rejecting the crucial assumption on which the Dummettian argument depends.

Gödel's two incompleteness theorems are among the most important results in modern logic, and have deep implications for various issues. They concern the limits of provability in formal axiomatic theories. The first incompleteness theorem states that in any consistent formal system F within which a certain amount of arithmetic can be carried out, there are statements of the language of F which can neither be proved nor disproved in F. According to the second incompleteness theorem, such a formal system cannot prove that the system itself is consistent (assuming it is indeed consistent). These results have had a great impact on the philosophy of mathematics and logic. There have been attempts to apply the results also in other areas of philosophy such as the philosophy of mind, but these attempted applications are more controversial. The present entry surveys the two incompleteness theorems and various issues surrounding them.

Three influential forms of realism are distinguished and interrelated: realism about the external world, construed as a metaphysical doctrine; scientific realism about non-observable entities postulated in science; and semantic realism as defined by Dummett. Metaphysical realism about everyday physical objects is contrasted with idealism and phenomenalism, and several potent arguments against these latter views are reviewed. Three forms of scientific realism are then distinguished: (i) scientific theories and their existence postulates should be taken literally; (ii) the existence of unobservable entities posited by our most successful scientific theories is justified scientifically; and (iii) our best current scientific theories are at least approximately true. It is argued that only some form of scientific realism can make proper sense of certain episodes in the history of science. Finally, Dummett’s influential formulation of semantic issues about realism considered. Dummett argued that in some cases, the fundamental issue is not about the existence of entities, but rather about whether statements of some specified class (such as mathematics) have an objective truth value, independently of our means of knowing it. Dummett famously argued against such semantic realism and in favor of anti-realism. The relation of semantic realism to the metaphysical construal of realism and Dummett’s main argument against semantic realism is examined.
