Study is like the heaven's glorious sun,
That will not be deep-search'd with saucy looks; Small have continual plodders ever won,
Save base authority from others' books.
These earthly godfathers of heaven's lights That give a name to every fixed star,
Have no more profit of their shining nights Than those that walk and wot not what they are.
Love's Labour's Lost [1594—1595], I, i, 84
