Astronomy, that micography of heaven, is the most magnificent of the sciences. ... Astronomy has its clear side and its luminous side; on its clear side it is tinctured with algebra, on its luminous side with poetry.
Without stirring abroad, One can know the whole world; Without looking out of the window One can see the way of heaven. The further one goes The less one knows.
Study is like the heaven's glorious sun, That will not be deep-searched with saucy looks: Small have continual plodders ever won, Save base authority from others' books.
