3. Truth / B. Truthmakers / 3. Truthmaker Maximalism
The truth-maker principle is that every truth has a sufficient truth-maker [Forrest]
     Full Idea: Item x is said to be a sufficient truth-maker for truth-bearer p just in case necessarily if x exists then p is true. ...Every truth has a sufficient truth-maker. Hence, I take it, the sum of all sufficient truth-makers is a universal truth-maker.
     From: Peter Forrest (General Facts,Phys Necessity, and Metaph of Time [2006], 1)
     A reaction: Note that it is not 'necessary', because something else might make p true instead.
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
An 'abstraction principle' says two things are identical if they are 'equivalent' in some respect [Boolos]
     Full Idea: Hume's Principle has a structure Boolos calls an 'abstraction principle'. Within the scope of two universal quantifiers, a biconditional connects an identity between two things and an equivalence relation. It says we don't care about other differences.
     From: George Boolos (Is Hume's Principle analytic? [1997]), quoted by Michèle Friend - Introducing the Philosophy of Mathematics 3.7
     A reaction: This seems to be the traditional principle of abstraction by ignoring some properties, but dressed up in the clothes of formal logic. Frege tries to eliminate psychology, but Boolos implies that what we 'care about' is relevant.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
We don't condemn people for being bad at reasoning [Finlayson]
     Full Idea: We do not morally disapprove of people who are incompetent reasoners.
     From: James Gordon Finlayson (Habermas [2005], Ch.6:83)
     A reaction: Well, we don't morally disapprove simply of their lack of reasoning ability, but we may morally disapprove of their actions, which have arisen entirely from the disability.
23. Ethics / D. Deontological Ethics / 3. Universalisability
One can universalise good advice, but that doesn't make it an obligation [Finlayson]
     Full Idea: 'Early to bed and early to rise' is a universalizable maxim, but, though it might be good advice, there is obviously no such obligation.
     From: James Gordon Finlayson (Habermas [2005], Ch.6:83)
     A reaction: I take it that Kant's rule won't distinguish moral guidance from prudential guidance. Unfair, I think. I may be a lark, but when I universalise this maxim I see that it can't be willed as a universal rule, because we should tolerate the owls.
24. Political Theory / B. Nature of a State / 5. Culture
The 'culture industry' is an advertisement for the way things are [Finlayson]
     Full Idea: Critical theory said that culture unwittingly played the role of an advertisement for the way things are. Horkheimer and Adorno referred to this phenomenon as the 'culture industry'.
     From: James Gordon Finlayson (Habermas [2005], Ch.1:04)
     A reaction: An interesting perspective. However, absolutely everything is an advertisement for what it offers. I think this is especially true of moral (and immoral) actions.
