 Hume is usually read as delivering a negative verdict on the possibility of justifying inference I, via a premise such as  P8,  though as we have seen in section  section 2,  some have questioned whether Hume is best interpreted as drawing a conclusion about justification of inference I at all. In this section we examine approaches which question in different ways whether  premise P8  really does give a valid necessary condition for justification of inference I and propose various alternative conceptions of justification.
