Famous quotes containing the words counterfeit and/or pen:
“I can counterfeit the deep tragedian,
Speak, and look back, and pry on every side,
Tremble and start at wagging of a straw,
Intending deep suspicion. Ghastly looks
Are at my service like enforced smiles,
And both are ready in their offices
At any time to grace my stratagems.”
—William Shakespeare (1564–1616)
“It was a fatal day when the public discovered that the pen is mightier than the paving-stone, and can be made as offensive as the brickbat. They at once sought for the journalist, found him, developed him, and made him their industrious and well-paid servant. It is greatly to be regretted, for both their sakes.”
—Oscar Wilde (1854–1900)
