Closed Unbounded Class

Famous quotes containing the words closed and/or class:

    Because you live, O Christ,
    the spirit bird of hope is freed for flying,
    our cages of despair no longer keep us closed and life-denying.
    The stone has rolled away and death cannot imprison!
    O sing this Easter Day, for Jesus Christ has risen!
    Shirley Erena Murray (20th century)

    It is the mark of an educated man to look for precision in each class of things just so far as the nature of the subject admits; it is evidently equally foolish to accept probable reasoning from a mathematician and to demand from a rhetorician demonstrative proofs.
    Aristotle (384–323 B.C.)
