3. Truth / B. Truthmakers / 5. What Makes Truths / a. What makes truths

18901	Truthmakers are facts 'of' a domain, not something 'in' the domain [Sommers]
	Full Idea: A fact is an existential characteristic 'of' the domain; it is not something 'in' the domain. To search for truth-making facts in the world is indeed futile.
	From: Fred Sommers (Intellectual Autobiography [2005], 'Existence')
	A reaction: Attacking Austin on truth. Helpful. It is hard to see how a physical object has a mysterious power to 'make' a truth. No energy-transfer seems involved in the making. Animals think true thoughts; I suspect that concerns their mental maps of the world.

4. Formal Logic / A. Syllogistic Logic / 3. Term Logic

18904	'Predicable' terms come in charged pairs, with one the negation of the other [Sommers, by Engelbretsen]
	Full Idea: Sommers took the 'predicable' terms of any language to come in logically charged pairs. Examples might be red/nonred, massive/massless, tied/untied, in the house/not in the house. The idea that terms can be negated was essential for such pairing.
	From: report of Fred Sommers (Intellectual Autobiography [2005]) by George Engelbretsen - Trees, Terms and Truth 2
	A reaction: If, as Rumfitt says, we learn affirmation and negation as a single linguistic operation, this would fit well with it, though Rumfitt doubtless (as a fan of classical logic) prefers to negation sentences.

18895	Logic which maps ordinary reasoning must be transparent, and free of variables [Sommers]
	Full Idea: What would a 'laws of thought' logic that cast light on natural language deductive thinking be like? Such a logic must be variable-free, conforming to normal syntax, and its modes of reasoning must be transparent, to make them virtually instantaneous.
	From: Fred Sommers (Intellectual Autobiography [2005], 'How We')
	A reaction: This is the main motivation for Fred Sommers's creation of modern term logic. Even if you are up to your neck in modern symbolic logic (which I'm not), you have to find this idea appealing. You can't leave it to the psychologists.

5. Theory of Logic / D. Assumptions for Logic / 4. Identity in Logic

18897	Predicate logic has to spell out that its identity relation '=' is an equivalent relation [Sommers]
	Full Idea: Because predicate logic contrues identities dyadically, its account of inferences involving identity propositions needs laws or axioms of identity, explicitly asserting that the dyadic realtion in 'x=y' possesses symmetry, reflexivity and transitivity.
	From: Fred Sommers (Intellectual Autobiography [2005], 'Syllogistic')

5. Theory of Logic / E. Structures of Logic / 1. Logical Form

18893	Translating into quantificational idiom offers no clues as to how ordinary thinkers reason [Sommers]
	Full Idea: Modern predicate logic's methods of justification, which involve translation into an artificial quantificational idiom, offer no clues to how the average person, knowing no logic and adhering to the vernacular, is so logically adept.
	From: Fred Sommers (Intellectual Autobiography [2005], Intro)
	A reaction: Of course, people are very logically adept when the argument is simple (because, I guess, they can test it against the world), but not at all good when the reasoning becomes more complex. We do, though, reason in ordinary natural language.

5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / c. not

18903	Sommers promotes the old idea that negation basically refers to terms [Sommers, by Engelbretsen]
	Full Idea: If there is one idea that is the keystone of the edifice that constitutes Sommers's united philosophy it is that terms are the linguistic entities subject to negation in the most basic sense. It is a very old idea, tending to be rejected in modern times.
	From: report of Fred Sommers (Intellectual Autobiography [2005]) by George Engelbretsen - Trees, Terms and Truth 2
	A reaction: Negation in modern logic is an operator applied to sentences, typically writing '¬Fa', which denies that F is predicated of a, with Fa being an atomic sentence. Do we say 'not(Stan is happy)', or 'not-Stan is happy', or 'Stan is not-happy'? Third one?

5. Theory of Logic / E. Structures of Logic / 7. Predicates in Logic

18894	Predicates form a hierarchy, from the most general, down to names at the bottom [Sommers]
	Full Idea: We organise our concepts of predicability on a hierarchical tree. At the top are terms like 'interesting', 'exists', 'talked about', which are predicable of anything. At the bottom are names, and in between are predicables of some things and not others.
	From: Fred Sommers (Intellectual Autobiography [2005], 'Category')
	A reaction: The heirarchy seem be arranged simply by the scope of the predicate. 'Tallest' is predicable of anything in principle, but only of a few things in practice. Is 'John Doe' a name? What is 'cosmic' predicable of? Challenging!

7. Existence / D. Theories of Reality / 2. Realism

18900	Unfortunately for realists, modern logic cannot say that some fact exists [Sommers]
	Full Idea: Unfortunately for the fate of realist philosophy, modern logic's treatment of 'exists' is resolutely inhospitable to facts as referents of phrases of the form 'the existence or non-existence of φ'.
	From: Fred Sommers (Intellectual Autobiography [2005], 'Realism')
	A reaction: Predicate logic has to talk about objects, and then attribute predicates to them. It tends to treat a fact as 'Fa' - this object has this predicate, but that's not really how we understand facts.

15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality

8130	Qualities of experience are just representational aspects of experience ('Representationalism') [Harman, by Burge]
	Full Idea: Harman defended what came to be known as 'representationalism' - the view that qualitative aspects of experience are nothing other than representational aspects.
	From: report of Gilbert Harman (The Intrinsic Quality of Experience [1990]) by Tyler Burge - Philosophy of Mind: 1950-2000 p.459
	A reaction: Functionalists like Harman have a fairly intractable problem with the qualities of experience, and this may be clutching at straws. What does 'represent' mean? How is the representation achieved? Why that particular quale?

19. Language / B. Reference / 1. Reference theories

18898	In standard logic, names are the only way to refer [Sommers]
	Full Idea: In modern predicate logic, definite reference by proper names is the primary and sole form of reference.
	From: Fred Sommers (Intellectual Autobiography [2005], 'Reference')
	A reaction: Hence we have to translate definite descriptions into (logical) names, or else paraphrase them out of existence. The domain only contains 'objects', so only names can uniquely pick them out.

24. Political Theory / D. Ideologies / 3. Conservatism

23829	National leaders want to preserve necessary order - but always the existing order [Weil]
	Full Idea: Those in command see their duty as defending order, without which no social life can survive; and the only order they conceive is the existing one.
	From: Simone Weil (The Power of Words [1934], p.249)
	A reaction: She sympathises with them, because a new order is such an unknown. But it always struck me as weird that traditions are preserved because they are traditions, and not because they are good. (My old school, for example!).

24. Political Theory / D. Ideologies / 14. Nationalism

23828	National prestige consists of behaving as if you could beat the others in a war [Weil]
	Full Idea: What is called national prestige consists in behaving always in such a way as to demoralise other nations by giving them the impression that, if it comes to war, one would certainly defeat them.
	From: Simone Weil (The Power of Words [1934], p.244)
	A reaction: It's true. No nation gains prestige because of the happy lives of its citizens, or the creativity of its culture.

25. Social Practice / E. Policies / 1. War / a. Just wars

23827	Modern wars are fought in the name of empty words which are given capital letters [Weil]
	Full Idea: For our contemporaries the role of Helen in the Trojan War is is played by words with capital letters. …When empty words are given capital letters, then, on the slightest pretext, men will begin shedding blood for them and piling up ruin in their name.
	From: Simone Weil (The Power of Words [1934], p.241)
	A reaction: This seems particularly true of the 1930s, where specific dogmatic ideologies seemed to grip and divide people. Simple aggressive nationalism seems to be the cause of current wars, now the fear of Communism has diminished.
