I'm guided only by reason. I was given no other guide. The light it shades in useless? I have no other light.

If the world's Creator
Had wanted me to be
Different from how I am,
He'd have made me differently.

He gave me eyes for seeing,
I look,
I see,
I believe.
How can I dare say:
"Blindness would be a blessing"?

Beside my gaze, God
Gave me reason, for going
Beyond what eyes can see---
The vision we call knowing.

If seeing is being deceived,
And thinking is going astray,
I don't know.
I received them
From Good as my truth and way.
