5. Theory of Logic / F. Referring in Logic / 1. Naming / e. Empty names
Unreflectively, we all assume there are nonexistents, and we can refer to them [Reimer]
     Full Idea: As speakers of the language, we unreflectively assume that there are nonexistents, and that reference to them is possible.
     From: Marga Reimer (The Problem of Empty Names [2001], p.499), quoted by Sarah Sawyer - Empty Names 4
     A reaction: Sarah Swoyer quotes this as a good solution to the problem of empty names, and I like it. It introduces a two-tier picture of our understanding of the world, as 'unreflective' and 'reflective', but that seems good. We accept numbers 'unreflectively'.
11. Knowledge Aims / A. Knowledge / 1. Knowledge
Knowledge is a quality existing subjectively in the soul [William of Ockham]
     Full Idea: Knowledge is a certain quality which exists in the soul as its subject ('existens subiective in anima').
     From: William of Ockham (Expositio super viii libros [1340], Prologue)
     A reaction: One might say here that knowledge is a property, and so it might not be susceptible to further analysis. It invites the question of how you could know by introspection that you have got it, which would be an extreme internalist view.
Sometimes 'knowledge' just concerns the conclusion, sometimes the whole demonstration [William of Ockham]
     Full Idea: Sometimes 'knowledge' means evident cognition of the conclusion alone, sometimes of the demonstration as a whole.
     From: William of Ockham (Expositio super viii libros [1340], Prologue)
     A reaction: 'Demonstration' will be something like Greek 'logos' - full understanding, ability to explain and give reasons. William is certainly right about normal usage. I know the answer in a quiz, without any requirement for justifications.
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
Knowledge is certain cognition of something that is true [William of Ockham]
     Full Idea: Knowledge is certain cognition of something that is true.
     From: William of Ockham (Expositio super viii libros [1340], Prologue)
     A reaction: This view has problems. William is not facing up to the sceptical questions which can shake any degree of certainty, and also that someone who lacked self-confidence might know many things while always feeling uncertain about them. 'Cognition' must go!
27. Natural Reality / G. Biology / 3. Evolution
I don't see how mere moving matter can lead to the bodies of men and animals, and especially their seeds [Boyle]
     Full Idea: I confess I cannot well conceive how from matter, barely put into motion and left to itself, there could emerge such curious fabricks as the bodies of men and perfect animals, and more admirably contrived parcels of matter, as seeds of living creatures.
     From: Robert Boyle (The Sceptical Chemist [1661], p.569), quoted by Peter Alexander - Ideas, Qualities and Corpuscles
     A reaction: This is here to show that one of the most brilliant intellects of the seventeenth century thought carefully about this question and couldn't answer it. Natural selection really was a rather clever idea.
