Hi Bruno Marchal Semantic truth I think is 1p (personal, private) truth,

Truth is always semantical, and it can be 3p (it usually is).

`Subjective truth, like with feeling, sensations, ... is 1p, but it is`

`only a personal relative view on something bigger. You might be`

`conflating God and the inner God, somehow.`

`Semantic is a sub-branch of mathematical logic, usually known as model`

`theory.`

`Note that logician use "model" in the sense of the painters. the model`

`is the reality, not the theory used to describe the reality. Logicians`

`studied explicitly the relation between theories and their models.`

`The 1p comes when *some* representable beliefs are true. A bit like`

`when you plunge a map in the territory described by the map: there`

`will be a fixed point which is the same in the territory and in`

`reality (the famous: "you are here" point).`

which mnakes it contingent, while logical truth is necessary

`Even logical truth can be said contingent on the logic chosen. There`

`are many logics. Now for a platonist, classical logic is single out,`

`but not as the most true one, but as the one which is the simpler to`

`make sense on ... the other logics.`

as well as public or 3p truth. I think comnputers have problems with 1p truth because for one thing the coding is done by someone outside.

`The 1p truth of the machine is not coded in the machine. Some actual`

`machines knows already that, and can justified that If there are`

`machine (and from outside we can know this to correct) then the 1p-`

`truth is not codable. The 1p truth are more related to the relation`

`between belief and reality (not necessarily physical reality, except`

`for observation and sensation).`

Even the simple, and apparently formal Bp & p is NOT codable.

`Most truth about machine, including some that they can know, are not`

`codable.`

Many things true about us is not codable either. Bruno

You confuse the propositional constant T, withthe semantical notion of truth. The first is expressible/definableformally (indeed by T, or by "0 = 0" in arithmetic), the second isnot (Tarski theorem). When we say that truth is preserved by therules of inference, we are concerned with the second notion.In applications it is interpreted as if it were the correspondencemeaning of 'true'.Like in arithmetic. Truth of "ExP(x)" means that it exists a n suchthat P(n), at the "metalevel", which is the bare level in logic(that explains many confusion).But like all applications of mathematics, it may be onlyapproximate.Yes, but for arithmetic it is pretty clear, as we share ourintuition on the so-called standard finite numbers.Bruno http://iridia.ulb.ac.be/~marchal/ --You received this message because you are subscribed to the GoogleGroups "Everything List" group.To post to this group, send email to everything-list@googlegroups.com.To unsubscribe from this group, send email to everything-list+unsubscr...@googlegroups.com.For more options, visit this group at http://groups.google.com/group/everything-list?hl=en.
