“And the pleasure of discovery differs from
other pleasures in this [...] Other desires perish
in their gratification, but the desire of knowledge
never: the eye is not satisfied with seeing nor
the ear filled with hearing. Other desires
become the occasion of pain through dearth of
the material to gratify them, but not the desire
of knowledge: the sum of things to be known is
inexhaustible, and however long we read we
shall never come to the end of our story-book.”

A.E. Housman, 1892
