Quote by Kuhn, Thomas
"An accepted theory is not overturned simply because an anomaly appears; the commitment to the existing framework is too strong."
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."
