We Must Never Make Experiments To Confirm

The Investigator Should Have A Robust Faith - And Yet Not Believe.

A Discovery Is Generally An Unforeseen Relation Not Included In Theory.

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.

Theories Are Like A Stairway; By Climbing, Science Widens Its Horizon More And More, Because Theories Embody And Necessarily Include Proportionately More Facts As They Advance.

Real Science Exists, Then, Only From The Moment When A Phenomenon Is Accurately Defined As To Its Nature And Rigorously Determined In Relation To Its Material Conditions, That Is, When Its Law Is Known. Before That, We Have Only Groping And Empiricism.
