The Growth Of Knowledge Depends Entirely Upon Disagreement.

Science Is Not A System Of Certain, Or -established, Statements; Nor Is It A System Which Steadily Advances Towards A State Of Finality... And Our Guesses Are Guided By The Unscientific, The Metaphysical (though Biologically Explicable) Faith In Laws, In Regularities Which We Can Uncover-discover. Like Bacon, We Might Describe Our Own Contemporary Science-'the Method Of Reasoning Which Men Now Ordinarily Apply To Nature'-as Consisting Of 'anticipations, Rash And Premature' And As 'prejudices'.

We Hate The Very Idea That Our Own Ideas May Be Mistaken, So We Cling Dogmatically To Our Conjectures.

[the Aim Of Science Is] To Explain What So Far Has Taken To Be An Explicans, Such As A Law Of Nature. The Task Of Empirical Science Constantly Renews Itself. We May Go On Forever, Proceeding To Explanations Of A Higher And Higher Universality.

We Do Not Choose Political Freedom Because It Promises Us This Or That. We Choose It Because It Makes Possible The Only Dignified Form Of Human Coexistence, The Only Form In Which We Can Be Fully Responsible For Ourselves. Whether We Realize Its Possibilities Depends On All Kinds Of Things — And Above All On Ourselves.
