Even Mistaken Hypotheses And Theories Are Of

We Achieve More Than We Know. We Know More Than We Understand. We Understand More Than We Can Explain.

It Is What We Know Already That Often Prevents Us From Learning.

Mediocre Men Often Have The Most Acquired Knowledge

To Be Worthy Of The Name, An Experimenter Must Be At Once Theorist And Practitioner. While He Must Completely Master The Art Of Establishing Experimental Facts, Which Are The Materials Of Science, He Must Also Clearly Understand The Scientific Principles Which Guide His Reasoning Through The Varied Experimental Study Of Natural Phenomena. We Cannot Separate These Two Things: Head And Hand. An Able Hand, Without A Head To Direct It, Is A Blind Tool; The Head Is Powerless Without Its Executive Hand.

Men Who Have Excessive Faith In Their Theories Or Ideas Are Not Only Ill Prepared For Making Discoveries; They Also Make Very Poor Observations. Of Necessity, They Observe With A Preconceived Idea, And When They Devise An Experiment, They Can See, In Its Results,only A Confirmation Of Their Theory. In This Way They Distort Observation And Often Neglect Very Important Facts Because They Do Not Further Their Aim.
