In fact, it is propinquity that usually gives the facer to the logic
La Fontaine, however, was declared conqueror, on account of his profound erudition and his irrefragable logic
. Conrart obtained the compensation due to an unsuccessful combatant; he was praised for the loyalty of his intentions, and the purity of his conscience.
"I suppose you are always interfering with your own feelings,and those of other people, and dogmatizing about the irrationality of this, that, and the other sentiment, and then ordering it to be suppressed because you imagine it to be inconsistent with logic."
"No; though I have neither logic nor wealth of words, yet in a case where my opinion really differed from yours, I would adhere to it when I had not another word to say in its defence; you should be baffled by dumb determination.
"The best sword arm in all Christendom needs no other logic
than the sword, I should think," said Brus, returning to his work.
When at long intervals we turn over their abstruse pages, wonderful seems the calm and grand air of these few, these great spiritual lords who have walked in the world,--these of the old religion,--dwelling in a worship which makes the sanctities of Christianity look parvenues and popular; for "persuasion is in soul, but necessity is in intellect." This band of grandees, Hermes, Heraclitus, Empedocles, Plato, Plotinus, Olympiodorus, Proclus, Synesius and the rest, have somewhat so vast in their logic
, so primary in their thinking, that it seems antecedent to all the ordinary distinctions of rhetoric and literature, and to be at once poetry and music and dancing and astronomy and mathematics.
This is true for the Boolean logic
where one deals with 100% truths, but in modern logics
we work with partial truths.
To patch the logics
of the modified circuit, we prepare available spare cell list.
Wolenski comes up with a supposed reductio of the claim that (T)-equivalences are analytic (234-236); but the argument presupposes that one can push the analyticity claim into the object-language and that derivability distributes over equivalences, which need not hold in non-standard logics
. Wolenski also comes up with a (new) paradox directed at theories like verificationism, which pose conditions on a sentence being meaningful (318); but the argument assumes that a sentence which is meaningful and wrongly says of itself that it isn't thereby (i.e., by being false) says that it is false.
Conditional and preferential logics
; proof methods and theorem proving.
134.) (2) Since some nonclassical consequence relations do not require necessary truth preservation (for example, the consequence relation of Priest's LP), Hanna's characterization of nonclassical logics
"Logica Universalis" will be produced twice a year to carry research papers related to universal features of logics
. Topics covered include general tools and techniques for studying already existing logics
and building new ones, the study of classes of logics
, the scope of validity, and the philosophical and historical aspects of general concepts of logic
