I feel that my bosom is big with a sigh.

Oh! why do I see that all knowledge is vain;

That Science finds Error still keep in her train;

That Imposture or Darkness, with Doubt and Surmise,

Will mislead, will perplex, and then baffle the wise,

Who often, when labours have shorten'd their span,

Declare—not to know—is the province of man?

In life, as in learning, our views are confin'd,

Our discernment too weak to discover the mind,

Which, subdued and irresolute, keeps out of sight;
