And dare we to this fancy give,
    That had the wild oat not been sown,
    The soil, left barren, scarce had grown
The grain by which a man may live?

Or, if we held the doctrine sound
    For life outliving heats of youth,
    Yet who would preach it as a truth
To those that eddy round and round?

Hold thou the good: define it well:
    For fear divine Philosophy
    Should push beyond her mark, and be
Procuress to the Lords of Hell.
