Philosophy of science - underdetermination - the complexities of the notion of falsification, originally diagnosed by duhem, had considerable impact on contemporary philosophy of science through the work of the american philosopher wvo quine (1908–2000) quine proposed a general thesis of the underdetermination of theory by evidence, arguing that it is always possible to preserve any.

In the philosophy of science, underdetermination refers to situations where the evidence available is insufficient to identify which belief one should hold about that evidence for example, if all that was known was that exactly $10 was spent on apples and oranges, and that apples cost $1 and oranges $2, then one would know enough to eliminate some possibilities (eg, 6 oranges could not have. My idea is that the body of evidence that distinct theories hold in common, the phenomena that both theories save, may nonetheless provide differing support for the two theories, more reason to believe one than the other, more confirmation of. The underdetermination thesis poses a threat to rational choice of scientific theories we discuss two arguments for the thesis one draws its strength from deductivism together with the existence thesis, and the other is defended on the basis of the failure of a reliable inductive method. 2 donald gilles (1993) and larry laudan (1990) have each also suggested that multiple, distinct theses have been mistakenly conflated as “the” thesis of underdetermination, but each proceeds to divide up the terrain much differently than i have.
