### Famous quotes containing the word number:

A considerable percentage of the people we meet on the street are people who are empty inside, that is, they are actually already dead. It is fortunate for us that we do not see and do not know it. If we knew what a number of people are actually dead and what a number of these dead people govern our lives, we should go mad with horror.
George Gurdjieff (c. 1877–1949)

After a certain number of years our faces become our biographies. We get to be responsible for our faces.
Cynthia Ozick (b. 1928)

In a number of other cultures, fathers are not relegated to babysitter status, nor is their ability to be primary nurturers so readily dismissed.... We have evidence that in our own society men can rear and nurture their children competently and that men’s methods, although different from those of women, are imaginative and constructive.
Kyle D. Pruett (20th century)
