6 Primitive notions Situations
- Ontology
- A situation is an entity which unfolds
- some object.
- A situation is an entity which reveals
- the ontic structure of an object which
- occurs in it.
- Semantics
- A situation with respect to a language
- L is an ontic representation of an
- atomic sentence ? from L.
7Primitive notions Situations
- To nominalise situations or not to nominalise?
- Nominalise, but be careful!
8Primitive notions Situations
George W. Bush is a wise president of the USA.
- LANGUAGE
-
- INTENTIONAL
- WORLD
- REALITY
That George W. Bush is a wise president of the
USA.
That George W. Bush is a wise president of the
USA.
9Primitive notions Situations
- INTENTIONAL SITUATIONS
- They are heteronomous.
- Every sentence creates an intentional situation.
- There are no ontological regularities among
intentional situations.
- REAL SITUATIONS
- They are autonomous.
- Some sentences do not represent any real
situation. - There are some ontological regularities among
real situations.
10Axioms
- ASSERTED PRINCIPLES
- REJECTED PRINCIPLES
- ??? PRINCIPLES
11AxiomsAsserted
- (2.1) Every (real) situation is possible.
- (2.2) If a sentence ? represents a situation x
and a situation y, then xy. - (2.8) If a situation x obtains in a situation y,
then every object occurring in x occurs in y as
well. - (2.10) If X is the set of all situations in which
only o1, o2, , on occur, then there is a
situation which is the least upper bound of X
with respect to the relation of obtain in.
12AxiomsRejected
- (2.3) If a sentence ? represents the situation
x, then there is a situation represented by the
sentence It is not the case that ?.
13Axioms???
- (2.7?) If a sentence ? represents a situation x
and a sentence ? represents a - situation y, then there is a situation
represented by the sentence ? and ?.
14AxiomsWhy are negations not (genuine)
representational sentences?
George W. Bush is not Polish.
George W. Bush is American.
George W. Bush is German.
George W. Bush is Russian.
15AxiomsAre conjunctions representational
sentences?
- A possible world is a maximal ideal of situations
in the set of all situations. - A set X of situations is an ideal of situations
iff - (i) every part of every situation from X belongs
to X, - (ii) for every pair x, y of situations from X,
the join of x and y belongs to X.
16AxiomsWhat is relation?
- George Bush George W. Bush
- Geroge Bush is 70 years old. George W. Bush is
50 years old. - George Bush is 6 feet tall. George W. Bush is
7 feet tall. - George Bush knows English, George W. Bush
knows English. - German, and Russian.
- ... ...
- ... ...
The relation between George Bush and George W.
Bush
17AxiomsWhat is relation?
- (2.10) If X is the set of all situations in which
only o1, o2, , on occur, then there is a
situation which is the least upper bound of X
with respect to the relation of obtain in.
18Formalism
- ltS, O, ?, Ogt
- (i) S?O?,
- (ii) ??S?S,
- (iii) lt ?\,
- (iv) O S ? ?(O).
Set of objects
Set of situations
Situation parthood
Object(s) in situation
19FormalismAuxiliary definitions
- X?Y ? ?x?X ?y?Y x?y.
- At(S) x?S ??y?S yltx.
- S(o) x?S o?O(x).
- IS(o1, o2, , on, W) x?W O(x)o1, o2, ,
on.
20Formalism ltS, O, ?, Ogt
- (C1) The relation ? is a partial order.
- (C2) W??,
- where W is the set of all maximal ideals in
ltS, ?gt - (C3) S?W.
- (C4) If x?y, then O(x)?O(y).
- (C5) ?x?S O(x)??.
- (C6) ?o?O S(o)??.
- (C7) If IS(o1,, on, W)??, then ?y?W ysup?
IS(o1,, on, W).
- ?
- ? 2.1 and 2.7
- 2.1
- 2.8
- definition of situation
- definition of situation
- 2.10
21FormalismHow expressive is it?
- structure of object in world
- range of object in world
- intrinsic structure of object in world
- intrinsic range of object in world
- existence of object
- essence of object
- ltS(o)?W, ?(S(o) ?W) gt
- sup S(o)?W
- ltIS(o, W), ?IS(o, W)gt
- sup IS(o, W)
- W(o) W?W S(o)?W??.
- x?Ess(o) ? ?W?W(o) x?IS(o, W).
22FormalismDependence
- An object o1 strongly depends on an object o2 in
a possible world W iff - o1 exists in W and S(o1)?W?S(o2)?W.
- An object o1 partially depends on an object o2 in
a possible world W iff - o1 exists in W and (S(o1)?W)?(S(o2)?W)??.
- An object o1 weakly depends on an object o2 in a
possible world W iff - o1 exists in W and S(o1)?W?S(o2)?W.
- An object o1 strongly (partially, weakly) depends
on an object o2 iff o1 strongly - (partially, weakly) depends on o2 in every
W?W(o1). - An object is strongly (weakly) independent in O
iff it does not weakly (strongly) - depend on any other object from O.
23FormalismExtensionalist NIOSO
- (C9) If x?At(S) or y?At(S), then xy ? ?z (zltx ?
zlty).
24FormalismLeibnizian NIOSO
- (C9) If ?W?W (S(o1)?WS(o2)?W), then o1o2.
- (C10) If S(o1)?WS(o2)?W??, then o1o2.
25ComparisonsRepresenting and truthmaking
- REPRESENTATION
- One sentence represents at most one
- situation.
- Tautologies do represent.
- Existential generalisations do not represent.
- TRUTH MAKING
- One sentence is made true by more than one truth
maker. - There are no truth-makers for tautologies.
- (Some) existential generalisations have
truth-makers.
26ComparisonsWhy do existential generalisations
not represent?
John runs quickly.
Someone runs quickly.
Someone does something quickly.
Someone does something somehow.
27ComparisonsNIOS and mereology
- SSP
- (i) that John runs quickly
- (ii) that John runs
- Not iii.
- There is no situation iii such that
- iii?i
- and
- iii and ii do not overlap.
