A Theory Is Just A Mathematical Model

Our Knowledge Can Only Be Finite, While Our Ignorance Must Necessarily Be Infinite.

A System Is Empirical Or Scientific Only If It Is Capable Of Being Tested By Experience. These Considerations Suggest That Not The Verifiability But The Falsifiability Of A System Is To Be Taken As A Criterion Of Demarcation... It Must Be Possible For An Empirical Or Scientific System To Be Refuted By Experience.

Our Belief In Any Particular Natural Law Cannot Have A Safer Basis Than Our Unsuccessful Critical Attempts To Refute It.
