Scientific Recommendations Criterion

The major aim of the present article is to reason on the minimum criterion for science; the possibility of mistaking and also presenting a criterion (standard) to penmen (test and experience). The method of the research is criticizing different approaches about scientific method and required standards (criterion) for scientific knowledge in three views: logical positivism, popper falsifiable theory and structures theory and also little validity teachings of dakosta and fereng. The authors of the survey conclude although there have been a variety of criterion and standards to accept the scientific suggestions over the history; but the possibility of mistake in scientific views is considered as a pre criterion which is an accepted factor in both logical positivism and popper falsifiable theory. If we omit the mentioned pre criterion then we will not be able to distinguish experimental and scientific knowledge from other human knowledge.
