Famous quotes containing the words guessing and/or stone:
“We shall do better to abandon the whole attempt to learn the truth ... unless we can trust to the human mind’s having such a power of guessing right that before very many hypotheses shall have been tried, intelligent guessing may be expected to lead us to one which will support all tests, leaving the vast majority of possible hypotheses unexamined.”
—Charles S. Pierce (1839–1914)
“Too long a sacrifice
Can make a stone of the heart.
O when may it suffice?”
—William Butler Yeats (1865–1939)
