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 don’t see America as a mainland, but as a sea, a big ocean. Sometimes a storm arises, a formidable current develops, and it seems it will engulf everything. Wait a moment, another current will appear and bring the first one to naught.”
—Jacques Maritain (1882–1973)
