The old problem of induction is the problem of justifying inductive inferences. What is traditionally required from such a justification is an argument that establishes that using inductive inferences does not lead us astray. Although it seems to be a meaningful question whether there is such a justification for our inductive practices, David Hume argues that there can be no such justification (Hume [1739–40] 2000; see the discussion of Hume in the entry on  the problem of induction). It is important to understand that Hume’s argument is general. It is not just an argument against a particular attempt to justify induction in the sense above, but a general argument that there can be no such justification at all.
