Famous quotes containing the words sufficient and/or explanation:
“They who do not understand that a man may be brought to hope that which of all things is the most grievous to him, have not observed with sufficient closeness the perversity of the human mind.”
—Anthony Trollope (1815–1882)
“Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind’s eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.”
—Richard Dawkins (b. 1941)
