Pis-Aller

"Man is blind because of sin,
Revelation makes him sure;
Without that, who looks within,
Looks in vain, for all's obscure."

Nay, look closer into man!
Tell me, can you find indeed
Nothing sure, no moral plan
Clear prescribed, without your creed?

"No, I nothing can perceive!
Without that, all's dark for men.
That, or nothing, I believe."--
For God's sake, believe it then!
