"Invisible, Impalpable forces streaming around us and through us; per- 

 petual change and transformation on every hand; every day a day of crea- 

 tion, every night a revelation of unspeakable grandeur; suns and systems 

 forming in the cyclones of Stardust; the whole starry host of heaven flowing 

 like a meadow brook." — John Burroughs. 



"Progressive evolution is the universal plan. Everything which we meet 

 in the world around us, matter and mind, every individual and all con- 

 gregated masses, begin their course as germs and unfold in slow progres- 

 sion. . . . The faculties of all intelligent creation,, all that you call mind, 

 all that you call heart, are framed for an interminable series of evolu- 

 tions. ... It is not mainly the mould of this mighty frame of things which 

 establishes it, it is the fact that creation is eternally unfolding new resources 

 and presenting itself under successive and amazing combinations of which 

 no creature in the universe had imagined it capable." — James McCloud, a 

 Presbyterian Minister of Lexington, Kentucky, in 1818, when Darwin was a 

 small boy.
