Quote by Kuhn, Thomas
"The presence of crises, the recourse to extraordinary measures, all these changes of gear performed by the community, are characteristically associated with periods in which paradigm shift occurs."
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."
