Letter to Rachel Gleason Brooks, May 5, 1930 
1930s
                                    
“The sixth pre-Christian century—the miraculous century of Buddha, Confucius and Lâo-Tse, of the Ionian philosophers and Pythagoras—was a turning point for the human species. A March breeze seemed to blow across the planet from China to Samos, stirring man into awareness, like the breath of Adam's nostrils. In the Ionian school of philosophy, rational thought was emerging from the mythological dream-world. …which, within the next two thousand years, would transform the species more radically than the previous two hundred thousand had done.”

                                        Lo que más interesante es en la naturaleza existen dos especies, unicamente dos especies que son expansionistas: el hombre y los insectos. Las demás especies son territoriales. El insecto es devorador, expansionista, hasta que se siegue expandiendo y no le importa. Y el hombre es así... las dos especies que van a acabar peleándose por el mundo van a ser insectos y hombres.
