A Theory Is Just A Mathematical Model

Philosophy Is A Necessary Activity Because We, All Of Us, Take A Great Number Of Things For Granted, And Many Of These Assumptions Are Of A Philosophical Character; We Act On Them In Private Life, In Politics, In Our Work, And In Every Other Sphere Of Our Lives -- But While Some Of These Assumptions Are No Doubt True, It Is Likely, That More Are False And Some Are Harmful. So The Critical Examination Of Our Presuppositions -- Which Is A Philosophical Activity -- Is Morally As Well As Intellectually Important.

Historically Speaking All - Or Very Nearly All - Scientific Theories Originate From Myths.

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.

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.

Genuine Philosophical Problems Are Always Rooted Outside Philosophy And They Die If These Roots Decay.
