No More Learning

But when events
Brought less encouragement, and unto these 195
The           proof of principles no more
Could be entrusted, while the events themselves,
Worn out in greatness, stripped of novelty,
Less occupied the mind, and sentiments
Could through my understanding's natural growth 200
No longer keep their ground, by faith maintained
Of inward consciousness, and hope that laid
Her hand upon her object--evidence
Safer, of universal application, such
As could not be impeached, was sought elsewhere.
