medieval scholarly tradition, it is further interesting to note, was still
so strong that in order to insure their permanent preservation Bacon
translated them into Latin--he took for granted that the English in which
he first composed them and in which they will always be known was only a
temporary vulgar tongue.

But Bacon's most important work, as we have already implied, was not in the
field of pure literature but in the general advancement of knowledge,
particularly knowledge of natural science; and of this great service we
must speak briefly. His avowal to Burghley, made as early as 1592, is
famous: 'I have taken all knowledge to be my province.' Briefly stated, his
purposes, constituting an absorbing and noble ambition, were to survey all
the learning of his time, in all lines of thought, natural science, morals,
politics, and the rest, to overthrow the current method of _a priori_
deduction, deduction resting, moreover, on very insufficient and
long-antiquated bases of observation, and to substitute for it as the
method of the future, unlimited fresh observation and experiment and
inductive reasoning. This enormous task was to be mapped out and its
results summarized in a Latin work called 'Magna Instauratio Scientiarum'
(The Great Renewal of Knowledge); but parts of this survey were necessarily
to be left for posterity to formulate, and of the rest Bacon actually
composed only a fraction. What may be called the first part appeared
originally in English in 1605 and is known by the abbreviated title, 'The
Advancement of Learning'; the expanded Latin form has the title, 'De
Augmentis Scientiarum.' Its exhaustive enumeration of the branches of
thought and knowledge, what has been accomplished in each and what may be
hoped for it in the future, is thoroughly fascinating, though even here
Bacon was not capable of passionate enthusiasm. However, the second part of
the work, 'Novum Organum' (The New Method), written in Latin and published
in 1620, is the most important. Most interesting here, perhaps, is the
