Thabo Mbeki, of South Africa, still seems reluctant to accept the otherwise universal hypothesis that AIDS is caused by the human immunodeficiency virus with all the dire medical consequences that flow from his refusal to take the right actions.Still, Mr Mbeki will not remain in office for ever, and it is his comparatively rich country that is leading the charge.
Assume that H is a universal hypothesis.
In the spirit of Boyle, though, Newton tends to treat his matter theory as instrumentally useful rather than as a universal hypothesis in search of further instances.
In Hempel's view, the key valid message of Nicod's statement is that the observation report that an object \(a\) displays properties \(F\) and \(G\) (e.g., that \(a\) is a swan and is white) confirms the universal hypothesis that all \(F\ -objects are \(G\)-objects (namely, that all swans are white).
We have chosen not to do this because Bonferroni-type corrections test the universal null hypotheses (i.e. that all hypotheses are simultaneously non-significant).
The key to rationality is the outward sign itself, i.e., elements of language, being made the object of attention (PD 206).[9] It is worth noting that, in a letter of 1869, Wright used the term consilience to explain the advantages of positivism over the "older philosophy".[10] Positivism, he said, is a system of "universal methods, hypotheses, and principles" founded on the sciences.
P-values are based on the assumption of the universal null hypothesis being correct, whereas a priori knowledge motivated several of the hypotheses we examined, specifically those related to different congener classes; in this situation, multiple comparisons can be justifiable as part of a careful and thorough evaluation of patterns of associations [ 98].
The results supported the hyperthermophilic universal ancestor hypothesis.
Cf. Wiltschko's Universal Spine hypothesis where layers such as CP (linking), IP (anchoring), AspP (point of view), and vP (classification) are distinguished.
No adjustments for multiple comparisons were done because the study was exploratory and we wanted to avoid excessive type II errors and to avoid inappropriately testing of a less relevant universal null-hypothesis [36].
