Every Important Idea In Science Sounds Strange

Concerned To Reconstruct Past Ideas, Historians Must Approach The Generation That Held Them As The Anthropologist Approaches An Alien Culture. They Must, That Is, Be Prepared At The Start To Find That Natives Speak A Different Language And Map Experience Into Different Categories From Those They Themselves Bring From Home. And They Must Take As Their Object The Discovery Of Those Categories And The Assimilation Of The Corresponding Language.

The Historian Of Science May Be Tempted To Exclaim That When Paradigms Change, The World Itself Changes With Them.

Though The World Does Not Change With A Change Of Paradigm, The Scientist Afterward Works In A Different World... I Am Convinced That We Must Learn To Make Sense Of Statements That At Least Resemble These. What Occurs During A Scientific Revolution Is Not Fully Reducible To A Re-interpretation Of Individual And Stable Data. In The First Place, The Data Are Not Unequivocally Stable.

Research Under A Paradigm Must Be A Particularly Effective Way Of Inducing Paradigm Change.

What A Man Sees Depends Both Upon What He Looks At And Also Upon What His Previous Visual-conceptual Experience Has Taught Him To See.
