_As to the Readers, ’tis, I suppose, so evident that candour of mind, and freedome from prejudice is requisite to all that desire to advantage themselves by reading other mens notions, that it need not be here insisted on with much earnestness; yet considering the Antiquity of this subject, and the novelty of the Arguments here produced, it seems to be more than ordinarily requisite for an impartial perusal of the ensuing Tract. Neither are the following Meditations to be slightly passed over, but with diligence and attention to be read; for as in mathematical demonstration, the careless missing of any one single Position may render the Conclusion obscure and sometimes inconsequent, so in these metaphysical Demonstrations, which (as, before has been noted from the illustrious Author thereof) for certainty do equal, if not excel Geometrical Propositions, the slight attention to any one particular Argument may frustrate the design of the whole discourse._ _The Reasoning therefore here being close and solid, and (as in Mathematicks) the knowledge of the latter depending on the knowledge of what went before, ’tis the duty of every Reader seriously to attend the Particulars, as also the connexion of the whole. Let him weigh the Arguments and perpend the Conclusions, and after a clear and distinct Knowledge, lett him pass his judgement._ _And to this end I shall make it my request to every Reader, that he would not be content with a single perusal of the following Discourses, but that he would often repeat his reading them over; for by this means the force of those Arguments, which at first may by chance escape the most diligent and attentive Peruser, by a second or third Essay may offer themselves more fully to his Consideration. This was the desire of our Author in an other of his pieces, I mean his ~Principles of Philosophy~, which I am sure do not require so strict an attention of mind, as these abstracted speculations; and therefore if it were his Request in that case, we may Reasonably think that ’twas no less his desire in this._ _When we come to speak of the Incomparable Author of these Meditations, we have reason to lament our own Ignorance, and to blame the Ingratitude of the Age wherein he lived, for not transmitting to Posterity more certain and ample Records of the Life and Conversation of this Excellent Philosopher, all that has been Written in this kind gives us only so much light into the Life of this Prodigious Man, as may make us wish for more; imparting which, I shall recommend the Readers to a further enquiry into the inward Thoughts, (largly discover’d in the Writings) of our Famous Author, of whose outward actions and condition we have so small knowledge._
