The Occurrence Of Successive Forms Of Life

Science ... Warns Me To Be Careful How I Adopt A View Which Jumps With My Preconceptions, And To Require Stronger Evidence For Such Belief Than For One To Which I Was Previously Hostile. My Business Is To Teach My Aspirations To Conform Themselves To Fact, Not To Try And Make Facts Harmonize With My Aspirations.

The Only Good That I Can See In The Demonstration Of The Truth Of "spiritualism" Is To Furnish An Additional Argument Against Suicide. Better Live A Crossing-sweeper Than Die And Be Made To Talk Twaddle By A "medium" Hired At A Guinea A Séance.

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.

Science Is Organized Common Sense Where Many A Beautiful Theory Was Killed By An Ugly Fact.

The Man Of Science Has Learned To Believe In Justification, Not By Faith, But By Verification.
