that Uneasiness, which People naturally have, when they perceive themselves to be Vitious. It would be unjust to finish this Preface, without saying something of _Aristotle's_ Life, that those who read his Work, may know something of him. He was the Son of _Nicomachus_, Physician of[22] _Amyntas_, and descended from _Esculapius_. His Mother was the Daughter of one of the Descendants of those, who Transplanted a Colony, from _Chalcis_ to _Stagira_, in _Macedonia_; that is to say, she was of Noble Extraction, on both sides. He was born at _Stagira_, about four Hundred Years, before our Saviour. At Eighteen Years of Age, he went to _Athens_, and abode with _Plato_, he pass'd twenty Years in his School, and when his Master was dead, he went to _Hermeas_ the Tyrant of _Atarna_, a City of _Mysia_; he went from thence to _Mytelene_, from whence he was call'd by _Philip_, to be his Son _Alexander's_ Tutor; he was eight Years, with that Young Prince, and after _Philip's_ Death, returned to _Athens_, where he Taught, in the _Lyceum_ twelve Years, till the Death of _Alexander_. For _Antipater_ having carried the War into _Greece, Aristotle_, who fancied, the _Athenians_ suspected him, by reason of the strict Friendship, which was between him, and the Viceroy of _Macedonia_, retir'd to _Calchis_, where he died soon after, by a Fit of Sickness in the sixty third Year of his Age. He left one Son, and one Daughter, both Young, and made _Antipater_ Executor of his Will, and Administrator of all his Goods, which were very considerable, if we may judge of them by _Alexander's_ Liberality, who gave him eight Hundred Talents, for his History of Animals, that is according to the lesser Talent, one hundred and forty Thousand Pounds Sterling, or according to the greater, one Hundred eighty six Thousand, six Hundred, sixty five Pounds, thirteen Shillings and four Pence. The most precious of his Moveables was his Library, which was afterwards Sold to _Ptolomy Philadelphus_, and which he had Enrich'd with four Hundred Volumes, of his own making. In those of his Writings which now remain, and are happily a considerable Number, we find a very discerning Spirit, a solid Judgment, a wonderful Method, prodigious Knowledge, and an Eloquence both strong and sweet. He himself found out more, than the most Knowing now, learn with a great deal of Labour and Pains, and as for those things which depended on the Vivacity of the Spirit, no Man ever carried his Knowledge further, or Establish'd more sure, or extensive Principles. In Dialecticks, Logick, Rhetorick, Politicks, and Morality, we have little but what he taught us.
