Because we leave all these discourses to the confused trust of our memory; because they be not tied to the tenour of a question: as Philosophers use sometimes, places; the Divine, in telling his opinion and reasons in religion; sometimes the Lawyer, in showing the causes and benefits of laws; sometimes a Natural Philosopher, in setting down the causes of any strange thing which the Story binds him to speak of; but most commonly a Moral Philosopher, either in the ethic part, where he sets forth virtues or vices and the natures of passions; or in the politic, when he doth (as often he doth) meddle sententiously with matters of Estate. Again, sometimes he gives precept of war, both offensive and defensive. And so, lastly, not professing any art as his matter leads him, he deals with all arts; which--because it carrieth the life of a lively example--it is wonderful what light it gives to the arts themselves; so as the great Civilians help themselves with the discourses of the Historians. So do Soldiers; and even Philosophers and Astronomers. But that I wish herein is this, that when you read any such thing, you straight bring it to his head, not only of what art; but by your logical subdivisions to the next member and parcel of the art. And so--as in a table--be it witty words, of which TACITUS is full; sentences, of which LIVY; or similitudes, whereof PLUTARCH: straight to lay it up in the right place of his storehouse--as either military, or more specially defensive military, or more particularly, defensive by fortification--and so lay it up. So likewise in politic matters. And such a little table you may easily make wherewith I would have you ever join the historical part; which is only the example of some stratagem, or good counsel, or such like. This write I to you, in great haste, of method, without method: but, with more leisure and study--if I do not find some book that satisfies--I will venture to write more largely of it unto you. Master SAVELL will, with ease, help you to set down such a table of remembrance to yourself; and for your sake I perceive he will do much; and if ever I be able, I will deserve it of him. One only thing, as it comes into my mind, let me remember you of, that you consider wherein the Historian excelleth, and that to note: as DION NICAEUS in the searching the secrets of government; TACITUS, in the pithy opening of the venom of wickedness; and so of the rest. My time--exceedingly short--will suffer me to write no more leisurely. STEPHEN can tell you who stands with me, while I am writing. Now, dear brother! take delight likewise in the mathematicals. Master SAVELL is excellent in them. I think you understand the sphere. If you do, I care little for any more astronomy in you. Arithmetic and Geometry, I would wish you well seen in: so as both in matter of number and measure, you might have a feeling and active judgment, I would you did bear the mechanical instruments, wherein the Dutch excel.
