Famous quotes containing the word progress:
“You can hardly convince a man of an error in a life-time, but must content yourself with the reflection that the progress of science is slow. If he is not convinced, his grandchildren may be. The geologists tell us that it took one hundred years to prove that fossils are organic, and one hundred and fifty more to prove that they are not to be referred to the Noachian deluge.”
—Henry David Thoreau (1817–1862)
“For all the injustices in our past and our present, we have to believe that in the free exchange of ideas, justice will prevail over injustice, tolerance over intolerance and progress over reaction.”
—Hillary Rodham Clinton (b. 1947)
“Discontent is the first step in the progress of a man or a nation.”
—Oscar Wilde (1854–1900)
