circumstances. Using a situational sentence is doing something by means

of given circumstances which no longer is correct only relative to these circumstances” (69). I have trouble understanding these statements, since it is, in a sense, obviously true that a statement about, say, the mat that is lying two paces from me now, will receive its value of either “true” or “false” through the condition of the mat. If I say, for example, that the mat is green, yet the mat is actually blue, the statement “The mat is green” will have a false value in virtue of how the mat actually is. How the mat actually is, is a circumstance. The statement is true or false relative to the circumstance of the object which the statement picks out and offers a description of.

What do you think? Am I missing something here?

]]>(1) I would disagree that logic aims at truth. Indeed, I would say that logic aims only at the goal of establishing a linguistic-relative, conditional truth where a standard, textbook, classical-logic argument is taken to be valid if and only if it is impossible for the premises to be true while the conclusion is false. This is not the same as aiming for truth; this is ensuring that should truth occur, this truth does not lead to falsity.

(2) You write: “For it is not possible to say that ‘7 + 5 = 12′ was true in the past but is not true now, nor that such truth perishes as the present moment passes into the future. That is to say, there is no point anywhere in time at which ‘7 + 5 = 12′ is not true.”

You may be interested in a counter-example from Graham Priest where it is indeed mathematically coherent to assert that a number is both equal to some other and is not equal to that same other number. See his paper on Inconsistent Arithmetic here: http://www.math.helsinki.fi/logic/LC2003/presentations/priest.pdf
