Quote by Kuhn, Thomas
"Crisis alone is not enough; there must also be a basis, though it need not be rational, for choosing a new paradigm over an old one."
More from Kuhn, Thomas
"Discovery commences with the awareness of anomaly."
"The scientist who pauses to examine his own practice will discover equally unsuspected things about the nature of knowledge itself."
"A paradigm is what you think with, not what you think about."
"Truth emerges more readily from error than from confusion."
