The Growth Of Knowledge Depends Entirely Upon

Almost Everyone... Seems To Be Quite Sure That The Differences Between The Methodologies Of History And Of The Natural Sciences Are Vast. For, We Are Assured, It Is Well Known That In The Natural Sciences We Start From Observation And Proceed By Induction To Theory. And Is It Not Obvious That In History We Proceed Very Differently? Yes, I Agree That We Proceed Very Differently. But We Do So In The Natural Sciences As Well.

It Is Easy To Obtain Confirmations, Or Verifications, For Nearly Every Theory-if We Look For Confirmations. Confirmations Should Count Only If They Are The Result Of Risky Predictions... A Theory Which Is Not Refutable By Any Conceivable Event Is Non-scientific. Irrefutability Is Not A Virtue Of A Theory (as People Often Think) But A Vice. Every Genuine Test Of A Theory Is An Attempt To Falsify It, Or Refute It.

A Theory Is Just A Mathematical Model To Describe The Observations.

Reason Like Science, Grows By Way Of Mutual Criticism; The Only Possible Way Of Planning Its Growth Is To Develop Those Institutions That Safeguard. The Freedom Of Thought

Our Aim As Scientists Is Objective Truth; More Truth, More Interesting Truth, More Intelligible Truth. We Cannot Reasonably Aim At Certainty. Once We Realize That Human Knowledge Is Fallible, We Realize Also That We Can Never Be Completely Certain That We Have Not Made A Mistake.
