Cohen's Induction Support

This article mainly elaborates Cohen's induction support theory, Cohen's induction support theory is to the Hume question one kind of reply and the solution。Cohen thought that his theory originates from Bacon, Mill and Keynes, He has developed the related quantity method from the Bacon three table's method foundations, Also Mill tested in five method foundations to sublimate the elimination induction, Finally also draws support from Keynes there:"reasonable faith" the concept has developed the induction support graduation thought。The second part is mainly elaborates Cohen to induce the support the theory system。Cohen famous honeybee experiment elaborates the induction support meaning with the aid of Feng Frisch's, Has established "the correlated variable" this important concept, And has introduced the induction graduation thought。Has developed with the Pascal probability different characteristic sentence:conjunction principle and negative principle, Has promoted Louise logic of modality system S4, Enabled the induction support the explanation to have more possible worlds。The third part mainly elaborated the Cohen logical system's non-monotonous characteristic, Differentiates Pascal and non-Pascal important different:conjunction principle, negative principle, The basic datum, Measure。The fourth part mainly proposed to Cohen logical system appropriate and inappropriate the appraisal。The inductive logic in the pursue experience appropriate aspect and the scientific epistemology's naturalizing tendency is consistent, Therefore the appraisal also proposes to appropriate from the naturalizing angle。Has analyzed the Cohen inductive logic system's characteristic, Inappropriate is mainly points out from Ju Shier the new ideal experiment, The new experiment pointed out that Cohen has not been able to reconstruct the elimination induction well.。Finally, Cohen's inductive logic system may also in widely the scope utilization.
