increased to fifty-eight; the Latin translation bears the title _Sermones
Fideles_. His great plan for a "restoration of the sciences" was intended
to be carried out in four, or rather, in six parts. But only the first two
parts of the _Instauratio Magna_ were developed: the _encyclopaedia_, or
division of all sciences[1], a chart of the _globus intellectualis_, on
which was depicted what each science had accomplished and what still
remained for each to do; and the development of the _new method_. Bacon
published his survey of the circle of the sciences in the English work, the
_Advancement of Learning_, 1605, a much enlarged revision of which, _De
Dignitate et Augmentis Scientiarum_, appeared in Latin in 1623. In 1612
he printed as a contribution to methodology the draft, _Cogitata et Visa_
(written 1607), later recast into the [first book of the] _Novum Organum_,
1620. This title, _Novum Organum_, of itself indicates opposition to
Aristotle, whose logical treatises had for ages been collected under the
title _Organon_. If in this work Bacon had given no connected exposition
of his reforming principles, but merely a series of aphorisms, and this
an incomplete one, the remaining parts are still more fragmentary, only
prefaces and scattered contributions having been reduced to writing. The
third part was to have been formed by a description of the world or natural
_history, Historia Naturalis_, and the last,--introduced by a _Scala
Intellectus_ (ladder of knowledge, illustrations of the method
by examples), and by _Prodromi_ (preliminary results of his own
inquiries),--by natural _science, Philosophia Secunda_. The best edition of
Bacon's works is the London one of Spedding, Ellis & Heath, 1857 _seq_., 7
vols., 2d ed., 1870; with 7 volumes additional of _The Letters and Life of
Francis Bacon, including His Occasional Works_, and a Commentary, by J.
Spedding, 1862-74. Spedding followed this further with a briefer _Account
of the Life and Times of Francis Bacon_, 2 vols., 1878[2].
