6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / b. Greek arithmetic
A number is not a multitude, but a unified ratio between quantities [Newton]
     Full Idea: By a Number we understand not so much a Multitude of Unities, as the abstracted Ratio of any Quantity to another Quantity of the same Kind, which we take for unity.
     From: Isaac Newton (Universal Arithmetick [1669]), quoted by John Mayberry - What Required for Foundation for Maths? p.407-2
     A reaction: This needs a metaphysics of 'kinds' (since lines can't have ratios with solids). Presumably Newton wants the real numbers to be more basic than the natural numbers. This is the transition from Greek to modern.
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
The Identity of Indiscernibles is really the same as the verification principle [Jolley]
     Full Idea: Various writers have noted that the Identity of Indiscernibles is really tantamount to the verification principle.
     From: Nicholas Jolley (Leibniz [2005], Ch.3)
     A reaction: Both principles are false, because they are the classic confusion of epistemology and ontology. The fact that you cannot 'discern' a difference between two things doesn't mean that there is no difference. Things beyond verification can still be discussed.
21. Aesthetics / C. Artistic Issues / 6. Value of Art
All art is quite useless [Wilde]
     Full Idea: All art is quite useless.
     From: Oscar Wilde (Preface to 'Dorian Gray' [1891])
     A reaction: Echoes Kant's thought that art is 'purposive without purpose'. Although I find Wilde's claims that morality has nothing to do with art to be naïve, I find this remark sympathetic. Art may play with moral feelings, but is unlikely to affect actions.
21. Aesthetics / C. Artistic Issues / 7. Art and Morality
Books are only well or badly written, not moral or immoral [Wilde]
     Full Idea: There is no such thing as a moral or an immoral book. Books are well written, or badly written. That is all.
     From: Oscar Wilde (Preface to 'Dorian Gray' [1891])
     A reaction: This is simply false. Novels that are viciously (or subtly) racist, sexist, homophobic, or egotistical can obviously be immoral. I could write a nasty story about Oscar Wilde. It might, though, be very well written. If life is moral, so are novels.
Having ethical sympathies is a bad mannerism of style in an artist [Wilde]
     Full Idea: No artist has ethical sympathies. An ethical sympathy in an artist is an unpardonable mannerism of style.
     From: Oscar Wilde (Preface to 'Dorian Gray' [1891])
     A reaction: This has a Nietzschean suggestion that the artist is 'beyond good and evil', and operates on some higher level of values, which in Wilde's case seem to be purely aesthetic. You can't justify a callous murder by executing it beautifully.
