his learned contemporary Peter Heylyn termed "a chymical brain," a brain
that was forever busy with new theories; and the leading theory was that
some lucky man would discover a key or philosopher's stone or magic
_sesame_ that must straightway unlock all the secrets of nature.

Meanwhile the real scientists of his age were discovering secrets in the
only sure way, of hard, self-denying work. Gilbert was studying magnetism,
Harvey discovering the circulation of the blood, Kepler determining the
laws that govern the planets' motions, Napier inventing logarithms, and
Galileo standing in ecstasy beneath the first telescope ever pointed at the
stars of heaven.

[Sidenote: HIS VAST PLANS]

Of the work of these scientific heroes Bacon had little knowledge, and for
their plodding methods he had no sympathy. He was Viscount, Lord
Chancellor, "high-browed Verulam," and his heaven-scaling
_Instauratio_ which, as he said, was "for the glory of the Creator and
for the relief of man's estate" must have something stupendous,
Elizabethan, about it, like the victory over the Armada. In his plans there
was always an impression of vastness; his miscellaneous works were like the
strange maps that geographers made when the wonders of a new world opened
upon their vision. Though he never made an important discovery, his
conviction that knowledge is power and that there are no metes or bounds to
knowledge, his belief that the mighty forces of nature are waiting to do
man's bidding, his thought of ships that navigate the air as easily as the
sea,--all this Baconian dream of mental empire inspired the scientific
world for three centuries. It was as thoroughly Elizabethan in its way as
the voyage of Drake or the plays of Shakespeare.
