Feeling Alone Guides The Mind.

True Science Teaches Us To Doubt And, In Ignorance, To Refrain.

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.

Man Can Learn Nothing Unless He Proceeds From The Known To The Unknown.

Priestley [said] That Each Discovery We Make Shows Us Many Others That Should Be Made.

The Better Educated We Are And The More Acquired Information We Have, The Better Prepared Shall We Find Our Minds For Making Great And Fruitful Discoveries.
