When I offered this title, I was engaging myself to investigate an apparent difference between two kinds of intentionality, in the hope that I should be able to find some firm logical criterion to distinguish them. I was less successful in this than I had hoped. I think I have gained a certain amount of insight into the logic and semantics of one kind of intentional context, largely due to the work I was doing while visiting the University of Pennsylvania (...) on Frege and on Michael Dummett’s monumental commentary on Frege. But as regards the other variety of intentionality I am still very much in the dark; so I am giving you thus far merely a progress report on that. (shrink)

The Euthyphro might well be given to undergraduates to read early in their philosophical training. The arguments are apparently simple, but some of them, as I shall show, lead naturally on to thorny problems of modern philosophy. Another benefit that could be gained from reading the Euthyphro is that the reader may learn to be forewarned against some common fallacies and debating tricks in moral disputes.

Această lucrare oferă o expunere a unor trăsături ale unei teorii semantice a logicilor modale. Pentru o anumită extensiune cuantificată a S5, această teorie a fost prezentată în ‘A Completeness Theorem in Modal Logic’ şi a fost rezumată în ‘Semantical Analysis of Modal Logic’ . Lucrarea de faţă se va concentra asupra unui aspect particular al teoriei – introducerea cuantificatorilor – şi se va restrînge în principal la o metodă particulară de a atinge acest scop. Accentul lucrării va fi pur (...) semantic şi în consecinţă se va omite folosirea tablourilor semantice, care este esenţială pentru o prezentare completă a teoriei . De asemenea, se va renunţa în mare parte la demonstraţii. (shrink)
