The Great Tragedy Of Science

From The Dawn Of Exact Knowledge To The Present Day, Observation, Experiment, And Speculation Have Gone Hand In Hand; And, Whenever Science Has Halted Or Strayed From The Right Path, It Has Been, Either Because Its Votaries Have Been Content With Mere Unverified Or Unverifiable Speculation (and This Is The Commonest Case, Because Observation And Experiment Are Hard Work, While Speculation Is Amusing); Or It Has Been, Because The Accumulation Of Details Of Observation Has For A Time Excluded Speculation.

The Improver Of Natural Knowledge Absolutely Refuses To Acknowledge Authority, As Such. For Him, Skepticism Is The Highest Of Duties; Blind Faith The One Unpardonable Sin.

Learn What Is True In Order To Do What Is Right.

Life Is Too Short To Occupy Oneself With The Slaying Of The Slain More Than Once.

As To Sagacity, I Should Say That His Judgement Respecting The Warmest Place And The Softest Cushion In A Room Is Infallible, His Punctuality At Meal Times Is Admirable, And His Pertinacity In Jumping On People's Shoulders Till They Give Him Some Of The Best Of What Is Going, Indicates Great Firmness.
