Seperti burung peralihan, naluri melayang jiwa petualang melampaui cakrawala hal-hal yang masuk akal, seolah-olah berniat konvoi ke negara induk dari mana ia telah terbang. Asli: Like birds of passage, the instincts drift the soul adventurously beyond the horizon of sensible things, as if intent on convoying it to the mother country from whence it had flown.

— Amos Bronson Alcott
