Famous quotes containing the words ring and/or current:
“Tell me where is fancy bred,
Or in the heart or in the head?
How begot, how nourished?
Reply, reply.
It is engendered in the eyes,
With gazing fed, and fancy dies
In the cradle where it lies.
Let us all ring fancy’s knell.
I’ll begin it. Ding, dong, bell.”
—William Shakespeare (1564–1616)
““I” is a militant social tendency, working to hold and enlarge its place in the general current of tendencies. So far as it can it waxes, as all life does. To think of it as apart from society is a palpable absurdity of which no one could be guilty who really saw it as a fact of life.”
—Charles Horton Cooley (1864–1929)
