13. Knowledge Criteria / A. Justification Problems / 1. Justification / a. Justification issues
Must all justification be inferential? [Ginet]
     Full Idea: The infinitist view of justification holds that every justification must be inferential: no other kind of justification is possible.
     From: Carl Ginet (Infinitism not solution to regress problem [2005], p.141)
     A reaction: This is the key question in discussing whether justification is foundational. I'm not sure whether 'inference' is the best word when something is evidence for something else. I am inclined to think that only propositions can be reasons.
Inference cannot originate justification, it can only transfer it from premises to conclusion [Ginet]
     Full Idea: Inference cannot originate justification, it can only transfer it from premises to conclusion. And so it cannot be that, if there actually occurs justification, it is all inferential.
     From: Carl Ginet (Infinitism not solution to regress problem [2005], p.148)
     A reaction: The idea that justification must have an 'origin' seems to beg the question. I take Klein's inifinitism to be a version of coherence, where the accumulation of good reasons adds up to justification. It is not purely inferential.
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Without confidence in our beliefs, how should we actually live? [Tuck]
     Full Idea: The central question for sceptics is if we lose confidence in the truth of most existing beliefs, then how do we actually live?
     From: Richard Tuck (Hobbes [1989], Ch.4)
     A reaction: Scepticism is not, of course, all or nothing. You can lead a 'normal' life in a virtual reality machine. I find it much more of a struggle to live if I lose faith in values, than if I lose faith in tables.
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / b. Prime matter
Prime matter is nothing when it is at rest [Leibniz]
     Full Idea: Primary matter is nothing if considered at rest.
     From: Gottfried Leibniz (Aristotle and Descartes on Matter [1671], p.90)
     A reaction: This goes with Leibniz's Idea 13393, that activity is the hallmark of existence. No one seems to have been able to make good sense of prime matter, and it plays little role in Aristotle's writings.
