The essays are scarcely less notable for style than for ideas. With characteristic intellectual independence Bacon strikes out for himself an extremely terse and clear manner of expression, doubtless influenced by such Latin authors as Tacitus, which stands in marked contrast to the formless diffuseness or artificial elaborateness of most Elizabethan and Jacobean prose. His unit of structure is always a short clause. The sentences are sometimes short, sometimes consist of a number of connected clauses; but they are always essentially loose rather than periodic; so that the thought is perfectly simple and its movement clear and systematic. The very numerous allusions to classical history and life are not the result of affectation, but merely indicate the natural furnishing of the mind of the educated Renaissance gentleman. The essays, it should be added, were evidently suggested and more or less influenced by those of the great French thinker, Montaigne, an earlier contemporary of Bacon. The hold of 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
