Philosophers Of Science Have Repeatedly

We See The World In Terms Of Our Theories.

The Man Who Is Striving To Solve A Problem Defined By Existing Knowledge And Technique Is Not, However, Just Looking Around. He Knows What He Wants To Achieve, And He Designs His Instruments And Directs His Thoughts Accordingly. Unanticipated Novelty, The New Discovery, Can Emerge Only To The Extent That His Anticipations About Nature And His Instruments Prove Wrong... There Is No Other Effective Way In Which Discoveries Might Be Generated.

Probably, The Single Most Prevalent Claim Advanced By The Proponents Of A New Paradigm Is That They Can Solve The Problems That Led The Old One To A Crisis.

We May... Have To Relinquish The Notion, Explicit Or Implicit, That Changes Of Paradigm Carry Scientists And Those Who Learn From Them Closer And Closer To The Truth... The Developmental Process Described In This Essay Has Been A Process Of Evolution From Primitive Beginnings-a Process Whose Successive Stages Are Characterized By An Increasingly Detailed And Refined Understanding Of Nature. But Nothing That Has Been Or Will Be Said Makes It A Process Of Evolution Toward Anything.

Normal Science Does Not Aim At Novelties Of Fact Or Theory And, When Successful, Finds None.
