The influence of gaslight or electric light on the growth of paraheliotropic trees

The feature of the heart–the inescapable feature of the heart that was known to our Ancient Precursors–known before we were even human–is that we can place our hand against it, and it feel it beating—

We do not know where it came from, or why it beats–but we know that for all those who live, it beats, and for all those who do not, it does not–

We know that when we fear, it beats faster–we know that when we calm, it beats slower.

Our hand against it, our hand against ourselves, and under that hand, warm to the touch, a drum we did not put there.
