Recently Professor Lee has suggested the analysis of the indicative conditional based on Sellars-Brandom's inferentialism. In this paper, I raise three questions. First, Professor Lee seems to misunderstand Sellars-Brandom in that he considers only the analytically valid arguments as materially valid inferences. Second, Professor Lee seems to misunderstand Sellars-Brandom in that whereas Sellars-Brandom talks about the common features of all kinds of conditionals including counterfactual conditionals, Professor Lee takes it as the analysis of the indicative conditional only. Third, either Professor Lee's analysis is incompatible with Sellars-Brandom inferentialism or his analysis is too general.

In my article published in 2008, I offered an inferentialist account of indicative conditionals. In her recent paper, Professor Seawha Kim raises three objections. First, I misunderstand Sellars-Brandom in that I take only concept-constitutive inferences as materially valid inferences. Second, Sellars and Brandom talk about the common features of all kinds of conditionals including counterfactual conditionals, but I construe their view as the analysis of the indicative conditionals only. Third, either my analysis is incompatible with Sellars-Brandom inferentialism or my analysis is too general. In this paper I argue that Seawha Kim's objections are all based on insufficient understandings of Sellars's and Brandom's views. First, it is Sellars's view that materially valid inferences are restricted within concept-constitutive inferences. Second, neither Sellars nor Brandom proposes a specific theory about the indicative conditional. Instead, they argue for the expressive role of the conditional. What I accept from their views is this expressive role of the conditional. The detailed proposals about the indicative conditional in my aforementioned article are my own. Third, the differences among conditionals have no direct bearing on Sellars-Brandom inferentialism. In addition, the meaning and role of the conditional expression 'if-then' do not require more than what I have argued for it.

According to David Hume, a deductive demonstration for inductive inference is not possible, because inductive inference is not deductive; and an inductive demonstration for inductive inference is not possible either, because such a demonstration is circular. Thus, on his view, there is no way of justifying inductive inference. Ever since Hume raised this problem of induction, a fair number of philosophers have tried to solve it. Nevertheless there is still no solution which is plausible enough to receive wide endorsement. According to Wilfrid Sellars, we cannot justify inductive inference by any theoretical reasoning; we can vindicate it only by a certain sort of practical reasoning. In this paper, I defend this Sellarsian proposal by developing and explaining it.
