I Need Scarcely Say That The Beginning And Maintenance Of Life On Earth Is Absolutely And Infinitely Beyond The Range Of All Sound Speculation In Dynamical Science. The Only Contribution Of Dynamics To Theoretical Biology Is Absolute Negation Of Automatic Commencement Or Automatic Maintenance Of Life.

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.
