The truth functional account of conditional statements ‘if A then B’ is not only inadequate; it eliminates the very conditionality expressed by ‘if’. Focusing only on the truth-values of the statements ‘A’ and ‘B’ and different combinations of these, one is bound to miss out on the conditional relation expressed between them. All approaches that treat conditionals as functions of their antecedents and consequents will end up in some sort of logical atomism where causal matters simply are reduced to the joint occurrence of A and B.

Evidence based medicine (EBM) is under critical debate, and person centered healthcare (PCH) has been proposed as an improvement. But is PCH offered as a supplement or as a replacement of EBM? Prima facie PCH only concerns the practice of medicine, while the contended features of EBM also include methods and medical model. I here argue that there are good philosophical reasons to see PCH as a radical alternative to the existing medical paradigm of EBM, since the two seem committed to conflicting ontologies. This paper aims to make explicit some of the most fundamental assumptions that motivate EBM and PCH, respectively, in order to show that the choice between them ultimately comes down to ontological preference. While EBM has a solid foundation in positivism, or what I here call Humeanism, PCH is more consistent with causal dispositionalism. I conclude that if there is a paradigmatic revolution on the way in medicine, it is first of all one of ontology.

In this paper I present some of Robert N. McLaughlin's critique of a truth functional approach to conditionals as it appears in his book On the Logic of Ordinary Conditionals. Based on his criticism I argue that the basic principles of logic together amount to epistemological and metaphysical implications that can only be accepted from a logical atomist perspective. Attempts to account for conditional relations within this philosophical framework will necessarily fail. I thus argue that it is not truth functionality as such that is the problem, but the philosophical foundation of modern logic.

Free will is a problem of modality, hampered by a commitment to modal dualism: the view that there is only necessity and pure contingency. If we have necessity, then things couldn't have been otherwise, against the Principle of Alternate Possibilities (AP). If there is complete contingency, then the agent seems to have no control over her actions, against the principle of Ultimate Authorship (UA). There is a third modality in natural causal processes, however. AP and UA can be reconciled if we allow both causation and agency to involve the dispositional modality.

Grice argues that indicative conditionals ‘if p then q’ have conventional, truth conditional meaning according to the material conditional ‘p  q’. In order to explain away the known paradoxes with this interpretation, he distinguishes between truth conditions and assertion conditions, attempting to demonstrate that the assumed connection between ‘p’ and ‘q’ (the Indirectness Condition) is a conversational implicature; hence a matter only relevant for the assertion conditions of a conditional. This paper argues that Grice fails to demonstrate i) that the Indirectness Condition is cancellable, hence a conversational implicature, ii) that the Indirectness Condition is not part of the conventional, truth-relevant meaning of ‘if’, and accordingly, iii) semantic or logical equivalence between indicative and material conditionals.

In an explanation ‘y because x’, because can be used to express an explanatory relation between an explanandum ‘y’ and an explanans ‘x’. But because can also be used to express the speaker’s reason for uttering ‘y’. This difference will be elucidated by connecting it with the distinction between the at-issue dimension and the speaker dimension of meaning. There are also internal relations between if and because that can help us find and analyse different uses of because, and thus also different types of explanatory relations.

If one’s solution to the free will problem is in terms of real causal powers of agents then one ought to be an incompatibilist. Some premises are contentious but the following new argument for incompatibilism is advanced: 1. If causal determinism is true, all events are necessitated2. If all events are necessitated, then there are no powers3. Free will consists in the exercise of an agent’s powersTherefore, if causal determinism is true, there is no free will; which is to say that free will is incompatible with determinism, so compatibilism is false

Språket vårt utgjør en stor del av vår identitet. Det er et redskap for kommunikasjon med andre mennesker, men også med oss selv. Vi uttrykker oss gjennom språket, og vi tenker ved hjelp av språket. Men hva er egentlig språk? Gjennom å ta for meg to vesensforskjellige tilnærminger til dette spørsmålet ønsker jeg å vise at det synet vi har på språk, har stor filosofiske betydning. Dette er fordi et språksyn nødvendigvis vil få konsekvenser for hvordan vi tenker om beslektede filosofiske spørsmål, som blant annet: – Hva er forholdet mellom språk og verden? – Hva er sannhet? – Hvordan får vi kunnskap om verden? – Hva gjør vi når vi bruker språk? – Hva er vår rolle som språkbrukere? – Hvordan lærer vi språk? Det er to ting som er viktig å avklare om vinklingen av denne artikkelen: Det første er at når jeg her velger å skissere to ulike filosofiske syn på språk, er det for å belyse de spørsmålene jeg har satt opp ovenfor, snarere enn å angripe eller fremme konkrete filosofiske teorier. Det andre er at når jeg her skriver om forholdet mellom språk og verden, og vår rolle som språkbrukere, vil jeg ta for gitt at dette omfatter alle naturlige språksystemer. Poengene mine er derfor ment å ha overføringsverdi til tegnspråk i sin alminnelighet, og selvfølgelig også til norsk tegnspråk. Dette innebærer at det jeg sier om ord, like gjerne kan sies om tegn. Målet med artikkelen er først og fremst å vise at språket må forstås som et gjennomgripende erkjennelsesmiddel i vårt møte med verden.

We claim that if a complete philosophy of evidence-based practice is intended, then attention to the nature of causation in health science is necessary. We identify how health science currently conceptualises causation by the way it prioritises some research methods over others. We then show how the current understanding of what causation is serves to constrain scientific progress. An alternative account of causation is offered. This is one of dispositionalism. We claim that by understanding causation from a dispositionalist stance, many of the processes within an evidence-based practice framework are better accounted for. Further, some of the problems associated with the health research, e.g. external validity of causal findings, dissolve.
