We'Re All Now Used To Thinking

We're all now used to thinking that we've been set apart Entirely as ourselves; that none other like us breathes: That to be a sovereign self, is like any other art; And our living shell is only by our own soul sheathed. But things are seldom simple, precise as you've been taught In school; things alive must share a common linkage, true: On the substance they depend; and scientists have sought To show the widely held and most palatable view: Little macroscopic worlds there would orbit on their own And scarcely would disturb their close neighbor's solo path. Each set of lungs; each entity is surely grown alone- And to say they are dependent is to risk our nature's wrath. But above there is a firmament of air and water, too This air moves as a whole, and it fills it sea to sea: Breathe in, and some fragment of my soul goes into you; Breathe out, and a little bit of you comes into me.
