Famous quotes containing the word rigid:
“Lets call something a rigid designator if in every possible world it designates the same object, a non-rigid or accidental designator if that is not the case. Of course we dont require that the objects exist in all possible worlds.... When we think of a property as essential to an object we usually mean that it is true of that object in any case where it would have existed. A rigid designator of a necessary existent can be called strongly rigid.”
—Saul Kripke (b. 1940)
“It is the custom of the Roman Church which I unworthily serve with the help of God, to tolerate some things, to turn a blind eye to some, following the spirit of discretion rather than the rigid letter of the law.”
—Pope Gregory VII (c. 10201085)
“The loosening, for some people, of rigid role definitions for men and women has shown that dads can be great at calming babiesif they take the time and make the effort to learn how. Its that time and effort that not only teaches the dad how to calm the babies, but also turns him into a parent, just as the time and effort the mother puts into the babies turns her into a parent.”
—Pamela Patrick Novotny (20th century)
