We actively perceive silence
Simon and Garfunkel’s chorus roils through my mind;
Silence must truly have a sound.
Ears must signal the brain when there is no sound
So I know that I hear nothing
We actively perceive darkness.
Lack of light is not completely the opposite
Of having light strike you retinas.
Eyes must signal the brain when there is no light
So I know that I see nothing.
If my brain must create silence,
How can I trust that I truly hear nothing?
If my brain must interpret darkness,
How can I know what darkness truly is?
If even the absences must be created by my brain
How can I know that they truly exist?
