Famous quotes containing the words magic and/or number:
“Mistress, there are portents abroad of magic and might,
And things that are yet to be done. Open the door!”
—Elizabeth Jane Coatsworth (b. 1893)
“Even in ordinary speech we call a person unreasonable whose outlook is narrow, who is conscious of one thing only at a time, and who is consequently the prey of his own caprice, whilst we describe a person as reasonable whose outlook is comprehensive, who is capable of looking at more than one side of a question and of grasping a number of details as parts of a whole.”
—G. Dawes Hicks (18621941)
