The ‘Responsibility Clause’

In gettier, justificationism on 03/08/2011 at 12:03 am

Take the term ‘justified’ as one of the following:

  1. S adopts a belief in an epistemically responsible manner (call this the ‘responsibility clause’).
  2. A relationship between the proposition believed and the grounds on which it is believed by S (call this the ‘grounds clause’).

As I will show, both clauses are needed in a plausible account of knowledge. The justification clause in the traditional doctrine that knowledge equals justified true belief must have these two components (1, 2). Furthermore, if 1 and 2 are satisfied, then the belief and truth clauses are reducible to the grounds and responsibility clauses — they will be necessarily believed and be true. The first part of this two-parter will show that the responsibility clause is not sufficient for a justificationist account of knowledge.

I will draw three lessons from the debasing demon. The first lesson is that all knowledge is imperilled by sceptical doubt, even knowledge of the cogito. This clarifies the range of scepticism. The second and related lesson is that anti-sceptical strategies relying on a residue of knowledge immune from doubt cannot succeed. The debasing demon leaves no residuum. The third lesson is that deception and debasement do not exhaust the forms of sceptical doubt. In that sense, there are more demons in epistemic hell than are dreamt of in epistemology. (Schaffer, 228)
