13. Knowledge Criteria / D. Scepticism / 3. Illusion Scepticism
A false object might give the same presentation as a true one [Arcesilaus, by Cicero]
     Full Idea: Arcesilaus said that no presentation proceeding from a true object is such that a presentation proceeding from a false one might not also be of the same form. This is the one argument that has held the field down to the present day.
     From: report of Arcesilaus (fragments/reports [c.275 BCE]) by M. Tullius Cicero - Academica II.24.77
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
An explanation is a causal graph [Woodward,J, by Strevens]
     Full Idea: On Woodward's manipulationist view, an explanation would take the form of a causal graph.
     From: report of James Woodward (Making Things Happen [2003]) by Michael Strevens - No Understanding without Explanation 1
     A reaction: The idea is that causation is all to do with how nature responds when you try to manipulate it. I'm certainly in favour of tying explanation closely to causation.
15. Nature of Minds / C. Capacities of Minds / 3. Abstraction by mind
Leaves are unequal, but we form the concept 'leaf' by discarding their individual differences [Nietzsche]
     Full Idea: Every concept arises through the setting equal of the unequal. Just as it is certain that one leaf is never wholly equal to another, so it is certain that the concept leaf is formed by arbitrarily discarding these individual differences.
     From: Friedrich Nietzsche (On Truth and Lies in a Nonmoral Sense [1872]), quoted by John Richardson - Nietzsche's System 2.1.1 n28
     A reaction: Nietzsche adds an interesting aspect to psychological abstraction, of abstracting away the differences between things, which we might label as the (further) capacity for Equalisation. If two cars differ only in a blemish, we abstract away the blemish.
