We can define true_belief(S,t,R,a,b,c)
As simply S believes(R,a,b,c) at time t & R(a,b,c)
And false_belief(S,t,R,a,b,c)
As S believes(R,a,b,c) at
time t & ~R(a,b,c)
We can define true_proposition(R,a,b,c)
As proposition(R,a,b,c) & R(a,b,c)
And define false_proposition(R,a,b,c)
As proposition(R,a,b,c) & ~R(a,b,c)
From the definition of proposition(R,a,b,c) and S believes R(a,b,c ) at time t
see http://dennisdarland.com/philosophy/proposition.html
and http://dennisdarland.com/philosophy/naming.html
It follows from S believes R(a,b,c) at t that
S understands R(a,b,c) at t thus
Proposition(R,a,b,c)
And from that it follows
True_proposition(R,a,b,c ) or false_proposition(R,a,b,c)
Which answers, I think, Wittgenstein’s objection which paralyzed Russell.
See The Collected Papers of Bertrand Russell (vol 7), Theory of Knowledge, The 1913 Manuscript pp. xxvii-xxviii.
Question: Isn’t it likely that Russell's paralysis involvesthe tension between 1) his need to have a relation occur as such, i.e.as relating entities ,in order to have a meaningful proposition and not amere list and 2) his need to explain false belief without introducingobjective false propositions? For consider (loves, Amy, Bob): if the relationloves actually relates the entities Amy and Bob, then what the beliefasserts –that Amy loves Bob—is true, but if the relation does not relate theentities—i.e. Amy doesn't love Bob—then there is nothing relating theterms (which might as well be loves, loves, loves; or Bob, Bob, Bob),hence no proposition the believer may be said to believe, i.e. eitherthere is no content or there is no false belief. To be paralyzed over the status of the relation andover the account of false belief is not to imply the instant rejectionof the (multiple relation) theory of belief, which Russell clings to,admitting its weaknesses, until 1918. Answer: I will explain what is a little different about myanalysis (my answer is a bit different than what Russell could have said,because my analysis is a bit different!), which you may not have noticed. The proposition R(a,b,c) will exist when ($S)($w)($x)($y)($z)($t) such that
· & symbol_1r(S,t,w,R)
· & symbol_0r(S,t,x,a)
· & symbol_0r(S,t,y,b)
· & symbol_0r(S,t,z,c)
·
·
Or on plain symbols: (ES)(Ew)(Ex)(Ey)(Ez)(Et) such that· & symbol_1r(S,t,w,R)
· & symbol+0r(S,t,x,a)
· & symbol_0r(S,t,y,b)
· & symbol_0r(S,t,z,c)
(this is implied by S believes R(a,b,c) at time t).
and also, if S believes it you will have thatbelief_r(S,w,x,y,z,t). This belief_r relates the
symbols w,x,y & z in a way to indicate what fact wouldhold if R(a,b,c). So the fact, though it may notexist, is indicated by the relations between thesymbols. Also, if there are propositions, which arenever believed, which seems likely, then we must saythe belief-R is not needed, but that the logical-form& symbol-R relations are then sufficient, themselves tomake such a proposition exist. These existing wouldimply a practice of using w,x,y & z to represent R,a,b& c, and the logical form rf of relating them.
Symbolic relations can hold between tokens andobjects. (actually via a norm for tokens). There canbe many utterances of tokens of "cat" but one wordcat. The relations of the tokens to the word areresemblance. The relation of the word to the objectis a practice.There are really (at least) two types of symbolicrelations. One for relations (between symbols andrelations) and another between symbols and objects. The when the symbols for a relation R and symbols forobjects a and b exist for Speaker S at Time t there isa proposition R(a,b). We speak of a corresponding factif a stands in the relation R to b.
