Famous quotes containing the word cities:
“1st Murderer. Where’s thy conscience now?...
2nd Murderer. I’ll not meddle with it. It makes a man a coward.... It fills a man full of obstacles. It made me once restore a purse of gold that by chance I found. It beggars any man that keeps it. It is turned out of towns and cities for a dangerous thing, and every man that means to live well endeavors to trust to himself and live without it.”
—William Shakespeare (1564–1616)
“This is not only a war of soldiers in uniform. It is a war of the people, of all the people, and it must be fought not only on the battlefield but in the cities and the villages, in the factories and on the farms, in the home and in the heart of every man, woman and child who loves freedom.”
—Arthur Wimperis (1874–1953)
“Again and again I am brought up against it, and again and again I resist it: I don’t want to believe it, even though it is almost palpable: the vast majority lack an intellectual conscience; indeed, it often seems to me that to demand such a thing is to be in the most populous cities as solitary as in the desert.”
—Friedrich Nietzsche (1844–1900)
