We Never Know What We Are Talking

I Think That We Shall Have To Get Accustomed To The Idea That We Must Not Look Upon Science As A 'body Of Knowledge,' But Rather As A System Of Hypotheses; That Is To Say, As A System Of Guesses Or Anticipations Which In Principle Cannot Be Justified, But With Which We Work As Long As They Stand Up To Tests, And Of Which We Are Never Justified In Saying That We Know They Are 'true' Or 'more Or Less Certain' Or Even 'probable.'

There Is No History Of Mankind, There Are Only Many Histories Of All Kinds Of Aspects Of Human Life. And One Of These Is The History Of Political Power. This Is Elevated Into The History Of The World.

I May Be Wrong And You May Be Right, And By An Effort, We May Get Nearer To The Truth

The Fundamental Thing About Human Languages Is That They Can And Should Be Used To Describe Something; And This Something Is, Somehow, The World. To Be Constantly And Almost Exclusively Interested In The Medium - In Spectacle-cleaning - Is A Result Of A Philosophical Mistake.

What Really Makes Science Grow Is New Ideas, Including False Ideas.
