This hypothesis proposes contact partly on the basis of perceived similarities between the flint tools of the Solutrean culture in modern-day France, Spain and Portugal (which thrived circa 20,000 to 15,000 BCE), and the Clovis culture of North America, which developed circa 9000 BCE.
When a hypothesis has survived a sufficient number of tests, it may be promoted to a scientific theory. A theory is a hypothesis that has survived many tests and seems to be consistent with other established scientific theories. Since a theory is a promoted hypothesis, it is of the same 'logical' species and shares the same logical limitations.
The theoretical foundations for what became known as the contrastive analysis hypothesis were formulated in Robert Lado's Linguistics Across Cultures (1957). In this book, Lado claimed that "those elements which are similar to [the learner's] native language will be simple for him, and those elements that are different will be difficult".
Proponents of horseshoe theory argue that the far-left and the far-right are closer to each other than either is to the political center. In popular discourse, the horseshoe theory asserts that advocates of the far-left and the far-right, rather than being at opposite and opposing ends of a linear continuum of the political spectrum, closely resemble each other, analogous to the way that the ...
In 1991 and again in 1996, Roy Miller defended the Altaic hypothesis and claimed that the criticisms of Clauson and Doerfer apply exclusively to the lexical correspondences, whereas the most pressing evidence for the theory is the similarities in verbal morphology. [44] [16]
The two-gospel hypothesis or Griesbach hypothesis is that the Gospel of Matthew was written before the Gospel of Luke, and that both were written earlier than the Gospel of Mark. [1] It is a proposed solution to the synoptic problem , which concerns the pattern of similarities and differences between the three Gospels of Matthew , Mark , and Luke .
In practice the politics and theology of the day determined the result of the dispute, but the nature of the controversy was a clear example of how different bundles of (usually implicit) auxiliary assumptions could support mutually inconsistent hypotheses concerning a single theory. In terms of either version of the Duhem–Quine thesis it ...
For Putnam, the working hypothesis represents a practical starting point in the design of an empirical research exploration. A contrasting example of this conception of the working hypothesis is illustrated by the brain-in-a-vat thought experiment. This experiment involves confronting the global skeptic position that we, in fact, are all just ...
