How to live brave, and how to still live free

How to live brave, and how to still live free
When death comes knocking round at every door,
Asking for me, when I don't know what's me:
These are the things I'm asking more and more.
Philosophers war with the scientists;
Are we cells, souls, synapses, or a joke?
Protesting, we raise ineffectual fists—
Meat-hearts, god-hearts, what matters is they broke.
How can I walk with courage toward the dark
That keeps its secrets still so perfectly?
What freedom can I claim beside the stark
Prerequisite of my mortality?
Questions have I, no answers on my part;
My hands lift skyward with my broken heart.
