A caution to the presumptuous and overly confident...

Then the Guide sang:

'Nearly they stood who fall;
Themselves as they look back
See always in the track
The one false step, where all
Even yet, by lightest swerve
Of foot not yet enslaved,
By smallest tremor of the smallest nerve,
Might have been saved.

'Nearly they fell who stand,
And with cold after fear
Look back to mark how near
They grazed the Sirens' land,
Wondering that subtle fate,
By threads so spidery fine,
The choice of ways so small, the event so great,
Should thus entwine.

'Therefore oh, man, have fear
Lest oldest fears be true,
Lest thou too far pursue
The road that seems so clear,
And step, secure, a hair's
Breadth past the hair-breadth bourne,
Which, being once crossed forever unawares,
Denies return.'
