The wise man's eyes are in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth to them all. The wise man's eyes, etc. - Well expressed by Choheleth: -
"The wise are circumspect, maturely weigh
The consequence of what they undertake,
Good ends propose, and fittest means apply
To accomplish their designs."
But the fool walketh in darkness -
"But fools, deprived
Of reason's guidance, or in darkness grope,
Or, unreflecting like a frantic man,
Who on the brink of some steep precipice
Attempts to run a race with heedless steps,
Rush to their own perdition."
One event happeneth to them all -
"Though wide the difference, what has human pride
To boast? Even I myself too plainly saw,
That one event to both alike befalls;
To various accidents of life exposed,
Without distinction: nor can wisdom screen
From dangers, disappointments, grief, and pain."
