If You Can Not Measure It, You

We All Confidently Believe That There Are At Present, And Have Been From Time Immemorial, Many Worlds Of Life Besides Our Own. . . . [this] May Seem Wild, And Visionary; All I Maintain Is That It Is Not Unscientific.

Questions Of Personal Priority, However Interesting They May Be To The Persons Concerned, Sink Into Insignificance In The Prospect Of Any Gain Of Deeper Insight Into The Secrets Of Nature.

Science Is Bound, By The Everlasting Vow Of Honour, To Face Fearlessly Every Problem Which Can Be Fairly Presented To It.

We Only Know God In His Works, But We Are Forced By Science To Admit And To Believe With Absolute Confidence In A Directive Power-in An Influence Other Than Physical, Or Dynamical, Or Electrical Forces.

In Physical Science A First Essential Step In The Direction Of Learning Any Subject Is To Find Principles Of Numerical Reckoning And Practicable Methods For Measuring Some Quality Connected With It. I Often Say That When You Can Measure What You Are Speaking About, And Express It In Numbers, You Know Something About It; But When You Cannot Measure It, When You Cannot Express It In Numbers, Your Knowledge Is Of A Meagre And Unsatisfactory Kind; It May Be The Beginning Of Knowledge, But You Have Scarcely In Your Thoughts Advanced To The Stage Of Science, Whatever The Matter May Be.
