A Fact In Itself Is

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.

Ardent Desire For Knowledge, In Fact, Is The One Motive Attracting And Supporting Investigators In Their Efforts; And Just This Knowledge, Really Grasped And Yet Always Flying Before Them, Becomes At Once Their Sole Torment And Their Sole Happiness. Those Who Do Not Know The Torment Of The Unknown Cannot Have The Joy Of Discovery Which Is Certainly The Liveliest That The Mind Of Man Can Ever Feel.

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

Well-observed Facts, Though Brought To Light By Passing Theories, Will Never Die; They Are The Material On Which Alone The House Of Science Will At Last Be Built.

First Causes Are Outside The Realm Of Science.
