Wherewith amidst a jostling throng
Of deeds, that each and all were wrong,
The doubting soul, from day to day,
Uneasy paralytic lay.
Come back again, my olden heart!
I said, Perceptions contradict,
Convictions come, anon depart,
And but themselves as false convict.
Assumptions, hasty, crude and vain,
Full oft to use will Science deign;
