Social science — a plaidoyer One of the most important tasks of social sciences is to explain the events, processes, and structures that take place and act in society. But the researcher cannot stop at this. As a consequence of the relations and connections that the researcher finds, a will and demand arise for critical reflection on the findings. To show that unemployment depends on rigid social institutions or adaptations to European economic aspirations...

With a few notable exceptions, such as the planetary systems, our most beautiful and exact applications of the laws of physics are all within the entirely artificial and precisely constrained environment of the modern laboratory … Haavelmo remarks that physicists are very clever. They confine their predictions to the outcomes of their experiments. They do not try to predict the course of a rock in the mountains and trace the development of the avalanche. It is only the crazy...

The relationship between logic and truth  [embedded content] To be ‘analytical’ and ‘logical’ is something most people find recommendable. These words have a positive connotation. Scientists think deeper than most other people because they use ‘logical’ and ‘analytical’ methods. In dictionaries, logic is often defined as “reasoning conducted or assessed according to strict principles of validity” and ‘analysis’ as having to do with “breaking something...

Why we need Big Theories  [embedded content]

Judea Pearl and interventionist causal models (wonkish) As X’s effect on some other variable in the system S depends on there being a possible intervention on X, and the possibility of an intervention in turn depends on the modularity of S, it is a necessary condition for something to be a cause that the system in which it is a cause is modular with respect to that factor. The requirement that all systems are modular with respect to their causes can, in a...

What properties do societies possess that might make them possible objects of knowledge for us? My strategy in developing an answer to this question will be effectively based on a pincer movement. But in deploying the pincer I shall concentrate first on the ontological question of the properties that societies possess, before shifting to the epistemological question of how these properties make them possible objects of knowledge for us. This is not an arbitrary order of...

The logic of scientific discovery It is because we are material things, possessed of the senses of sight and touch, that we accord priority in verifying existential claims to changes in material things. But scientists posit for these changes both continuants and causes, some of which are necessarily unperceivable. It is true that ‘that a flash or a bang occurs does not entail that anything flashes or bangs. “Let there be light” does not mean “let something...

Fyra viktiga drag är gemensamma för de olika rörelserna: Centrala idéer förklaras inte. Grunderna för en övertygelse anges inte. Framställningen av läran har en språklig stereotypi … När det gäller åberopandet av lärofäder råder samma stereotypi — ett begränsat antal namn återkommer. Heidegger, Foucault, och Derrida kommer tillbaka, åter och åter … Till de fyra punkterna vill jag emellertid … lägga till en femte: 5. Vederbörande har inte något väsentligen nytt att...
