What Is Faith?

Would that I might say "Faith" and understand it.
My faith is as a tenuous web-
Ensnaring yet elusive;
I may enmesh the day within it.
I see it burst its bonds, fleeing as
A butterfly out from its prison;
And doubt I then the strength
Of the web of my faith?
Would that I might say "Faith" and understand it.
Faith! The wise man who retains
His learning in a script, and learns
From the stars, kens weel he may not swing
A thing upon his faith,
Nor enmesh substance within its web.
Faith is the pulse of wisdom!
Ye may not have wisdom without faith,
And a wisdom which is not ended by surety-
Contains no faith.-Then what is "Faith"?
