In Regard To The Amount Of Difference

Whenever I Have Found That I Have Blundered, Or That My Work Has Been Imperfected, And When I Have Been Contemptuously Criticised, And Even When I Have Been Overpraised, So That I Have Felt Mortified, It Has Been My Greatest Comfort To Say Hundreds Of Times To Myself That 'i Have Worked As Hard As I Could, And No Man Can Do More Than This.'

Natural Selection Acts Solely By Accumulating Slight Successive Favorable Variations, It Can Produce No Great Or Sudden Modification; It Can Act Only By Very Short Steps.

A Bad Earthquake At Once Destroys The Oldest Associations: The World, The Very Emblem Of All That Is Solid, Has Moved Beneath Our Feet Like A Crust Over A Fluid; One Second Of Time Has Conveyed To The Mind A Strange Idea Of Insecurity, Which Hours Of Reflection Would Never Have Created.

It May Be Said That Natural Selection Is Daily And Hourly Scrutinizing, Throughout The World, Every Variation, Even The Slightest; Rejecting That Which Is Bad, Preserving And Adding Up All That Is Good; Silently And Insensibly Working, Wherever And Whenever Opportunity Offers, At The Improvement Of Each Organic Being In Relation To Its Organic And Inorganic Conditions Of Life.
