Magicians are no very good authority with me. But we experimentally see that women impart the marks of their fancy to the children they carry in the womb; witness her that was brought to bed of a Moor; and there was presented to Charles the Emperor and King of Bohemia, a girl from about Pisa, all over rough and covered with hair, whom her mother said to be so conceived by reason of a picture of St. John the Baptist, that hung within the curtains of her bed.
It is the same with beasts; witness Jacob's sheep, and the hares and partridges that the snow turns white upon the mountains. There was at my house, a little while ago, a cat seen watching a bird upon the top of a tree: these, for some time, mutually fixing their eyes one upon another, the bird at last let herself fall dead into the cat's claws, either dazzled by the force of its own imagination, or drawn by some attractive power of the cat. Such as are addicted to the pleasures of the field, have, I make no question, heard the story of the falconer, who having earnestly fixed his eyes upon a kite in the air; laid a wager that he would bring her down with the sole power of his sight, and did so, as it was said; for the tales I borrow I charge upon the consciences of those from whom I have them. The discourses are my own, and found themselves upon the proofs of reason, not of experience; to which every one has liberty to add his own examples; and who has none, let him not forbear, the number and varieties of accidents considered, to believe that there are plenty of them; if I do not apply them well, let some other do it for me. And, also, in the subject of which I treat, our manners and motions, testimonies and instances; how fabulous soever, provided they are possible, serve as well as the true; whether they have really happened or no, at Rome or Paris, to John or Peter, 'tis still within the verge of human capacity, which serves me to good use. I see, and make my advantage of it, as well in shadow as in substance; and amongst the various readings thereof in history, I cull out the most rare and memorable to fit my own turn. There are authors whose only end and design it is to give an account of things that have happened; mine, if I could arrive unto it, should be to deliver of what may happen. There is a just liberty allowed in the schools, of supposing similitudes, when they have none at hand. I do not, however, make any use of that privilege, and as to that matter, in superstitious religion, surpass all historical authority. In the examples which I here bring in, of what I have heard, read, done, or said, I have forbidden myself to dare to alter even the most light and indifferent circumstances; my conscience does not falsify one tittle; what my ignorance may do, I cannot say.
And this it is that makes me sometimes doubt in my own mind, whether a divine, or a philosopher, and such men of exact and tender prudence and conscience, are fit to write history: for how can they stake their reputation upon a popular faith? how be responsible for the opinions of men they do not know? and with what assurance deliver their conjectures for current pay? Of actions performed before their own eyes, wherein several persons were actors, they would be unwilling to give evidence upon oath before a judge; and there is no man, so familiarly known to them, for whose intentions they would become absolute caution. For my part, I think it less hazardous to write of things past, than present, by how much the writer is only to give an account of things every one knows he must of necessity borrow upon trust.
I am solicited to write the affairs of my own time by some, who fancy I look upon them with an eye less blinded with passion than another, and have a clearer insight into them by reason of the free access fortune has given me to the heads of various factions; but they do not consider, that to purchase the glory of Sallust, I would not give myself the trouble, sworn enemy as I am to obligation, assiduity, or perseverance: that there is nothing so contrary to my style, as a continued narrative, I so often interrupt and cut myself short in my writing for want of breath; I have neither composition nor explanation worth anything, and am ignorant, beyond a child, of the phrases and even the very words proper to express the most common things; and for that reason it is, that I have undertaken to say only what I can say, and have accommodated my subject to my strength. Should I take one to be my guide, peradventure I should not be able to keep pace with him; and in the ******* of my liberty might deliver judgments, which upon better thoughts, and according to reason, would be illegitimate and punishable. Plutarch would say of what he has delivered to us, that it is the work of others: that his examples are all and everywhere exactly true: that they are useful to posterity, and are presented with a lustre that will light us the way to virtue, is his own work. It is not of so dangerous consequence, as in a medicinal drug, whether an old story be so or so.
