Famous quotes related to ebb and flow:
“Thou shoreless flood, which in thy ebb and flow
Claspest the limits of mortality,
And sick of prey, yet howling on for more,
Vomitest thy wrecks on its inhospitable shore;”
—Percy Bysshe Shelley (1792–1822)
“For even satire is a form of sympathy. It is the way our sympathy flows and recoils that really determines our lives. And here lies the vast importance of the novel, properly handled. It can inform and lead into new places our sympathy away in recoil from things gone dead. Therefore the novel, properly handled, can reveal the most secret places of life: for it is the passional secret places of life, above all, that the tide of sensitive awareness needs to ebb and flow, cleansing and freshening.”
—D.H. (David Herbert)
“You are now
In London, that great sea, whose ebb and flow
At once is deaf and loud, and on the shore
Vomits its wrecks, and still howls on for more.
Yet in its depth what treasures!”
—Percy Bysshe Shelley (1792–1822)
