Such, however, was the continuing spell cast by the texts of the classics and by the strictly rationalistic, overwhelmingly deductive procedures of the Cartesians that, down until the beginning of the 19th century, these and other empirical materials were used, if at all, solely for illustrative purposes in the writings of the social philosophers.
Data were analyzed using a thematic content analysis approach incorporating both inductive and deductive procedures [ 34].
The interplay between inductive and deductive procedures in IPA means that as the analysis progresses existing theory can be endorsed, modified, and/or challenged.
An adaptive theory approach combines inductive and deductive procedures, meaning data were analyzed to confirm, refute and explore the previous identified theoretical concepts and links, but also to explore new theoretical concepts and links between concepts [ 9, 10].
Whereas Droysen speaks of the method of the historian as "understanding by investigation" (forschendes Verstehen), Humboldt sets off historical understanding from mere deductive rational procedures by calling it an assimilation of the investigative capability (forschende Kraft) and the object under investigation (GS Vol 4, 39).
Parallel to these in silico modeling, the data supplied from high throughput technologies has triggered the development of deductive top-down procedures, in order to complement and verify biological predictions obtained from constraints-based models [10], [11].
The motivation for categorial information theory is to model the cognitive procedures constituting deductive reasoning.
On the other hand, top-down procedures require deductive methods, whose main interest is to identify causal interactions between the individual genes measured by high-throughput technologies (Wagner, 2001; de la Fuente et al., 2002).
Unlike those fictional detectives who rely on their immense deductive powers or on police procedure, Maigret solves murders using mainly his psychological intuition and a patiently sought, compassionate understanding of the perpetrator's motives and emotional composition.
The motivation for categorial information theory is to provide a logical framework for modelling the properties of the very cognitive procedures that underpin deductive reasoning.
