Is knowing half the battle?

A poem on whether knowing is half the battle

I understand
The cracks and the thorns within
in this ivory tower
of my humble abode

I understand
The rot that festers within
seeping upwards in tendrils
from stone to the sky

I understand
The darkness that looms within
crowded with monsters
untold and unheard of

But why
does it still ache
to be powerless
with all the tools
near my fingertips
to banish asunder
the cracks
the thorns
the rot
the darkness

Perhaps
Knowing is not half the battle
For what man
would march in
over others who failed
to win a battle
that they know fully well.
