A Discourse of a Method of the Well Guiding of Reason and the Discovery of Truth in the Sciences by René Descartes (diy ebook reader .TXT) 📖

To the Understanding READER.

The Great DESCARTES (who may justly challenge the first place amongst the Philosophers of this Age) is the Author of this Discourse; which in the Originall was so well known, That it could be no mans but his own, that his Name was not affix'd to it: I need say no more either of Him or It; He is best made known by Himself, and his Writings want nothing but thy reading to commend them. But as those who cannot compasse the Originals of _Titian_ and _Van-Dyke_, are glad to adorne their Cabinets with the Copies of them; So be pleased favourably to receive his Picture from my hand, copied after his own Designe: You may therein observe the lines of a well form'd Minde, The hightnings of Truth, The sweetnings and shadowings of Probabilities, The falls and depths of Falshood; all which serve to perfect this Masterpiece. Now although my after-draught be rude and unpolished, and that perhaps I have touch'd it too boldly, The thoughts of so clear a Minde, being so extremely fine, That as the choisest words are too grosse, and fall short fully to expresse such sublime Notions; So it cannot be, but being transvested, it must necessarily lose very much of its native Lustre: Nay, although I am conscious (notwithstanding the care I have taken neither to wrong the Authours Sense, nor offend the Readers Ear) of many escapes which I have made; yet I so little doubt of being excused, That I am confident, my endeavour cannot but be gratefull to all Lovers of Learning; for whose benefit I have Englished, and to whom I addresse this Essay, which contains a Method, by the Rules whereof we may Shape our better part, Rectifie our Reason, Form our Manners and Square our Actions, Adorn our Mindes, and making a diligent Enquiry into Nature, wee may attain to the Knowledge of the Truth, which is the most desirable union in the World.

Our Authour also invites all letterd men to his assistance in the prosecution of this Search; That for the good of Mankinde, They would practise and communicate Experiments, for the use of all those who labour for the perfection of Arts and Sciences: Every man now being obliged to the furtherance of so beneficiall an Undertaking, I could not but lend my hand to open the Curtain, and discover this New Model of Philosophy; which I now publish, neither to humour the present, nor disgust former times; but rather that it may serve for an innocent Divertisement to those, who would rather Reform themselves, then the rest of the world; and who, having the same seeds and grounds, and knowing That there is nothing New under the Sun; That Novelty is but Oblivion, and that Knowledge is but Remembrance, will study to finde out in themselves, and restore to Posterity those lost Arts, which render Antiquity so venerable; and strive (if it be possible) to go beyond them in other things, as well as Time: Who minde not those things which are above, beyond, or without them; but would rather limit their desires by their power, then change the Course of Nature; Who seek the knowledge, and labour for the Conquest of themselves; Who have Vertue enough to make their own Fortune; And who prefer the Culture of the Minde before the Adorning of the Body; To such as these I present this Discourse (whose pardon I beg, for having so long detain'd them from so desirable a Conversation;) and conclude with this Advice of the Divine _Plato_:


Cogita in te, praeter Animum, nihil esse mirabile.



A DISCOURSE OF A METHOD, For the wel-guiding of Reason; AND The discovery of Truth in the SCIENCES.

If this Discourse seem too long to be read at once, it may be divided into six parts. In the first, are divers Considerations touching the Sciences. In the second, the principall Rules of that Method which the Author hath studyed. In the third, some of those in morality, which he hath drawn from this Method. In the fourth, the reasons whereby the existence of God and of the humane Soul is proved; which are the grounds of his Metaphysicks. In the fift, the order of these Physicall questions, which he hath examined, and particularly the explication of the hearts motion; with some other difficulties relating to Physick; as also the difference between our Souls and those of beasts. In the last, what he conceives requisit to make a further inquiry into Nature, then hath hitherto been made. And what reasons induc'd him to write.


PART. I.

Right understanding is the most equally divided thing in the World; for every one beleevs himself so well stor'd with it, that even those who in all other things are the hardest to be pleas'd, seldom desire more of it then they have; wherein it is not likely that all Men are deceived: But it rather witnesseth, That the faculty of right-judging and distinguishing truth from falshood (which is properly call'd, Understanding or Reason) is naturally equal in all Men. And as the diversity of our Opinions, is not, because some are more reasonable then others; but only that we direct our thoughts several ways, neither do we consider the same things. For 'tis not enough to have good faculties, but the principal is, to apply them well. The greatest Souls are as capable of the greatest Vices, as of the most eminent Vertues: And those who move but very slowly, may advance much farther, if they always follow the right way; then those who run and straggle from it.

For my part, I never presum'd that my Minde was more perfect in any thing then an ordinary Mans; nay, I have often wish'd to have had my thoughts as quick, my imagination as clear and distinct, and my memory as large and as ready as some other Men have had. And I know no Qualities which serve more then those to the perfection of the Minde; for as for Reason or Understanding, forasmuch as it is the only thing which makes us Men, and distinguisheth us from beasts, I will beleeve it to be entire in every One, and follow herein the common opinion of the Philosophers, who say, That there is only more or less among the Accidents, and not amongst the Forms or nature of the Individuals of one species.

But I shall not stick to say, That I beleeve my self very happy, in having encountred from my youth with certain ways which have led me to considerations and Maximes, from which I have found a Method; whereby methinks, I have the means by degrees to augment my knowledg, and by little and little to raise it up to the highest pitch, whereto the meaness of my capacity, & the short course of my life can permit it to attain. For I have already reaped such fruits from it, that although in the judgment I make of my self, I endevour always rather to incline to mistrust, then to presumption. And looking on the divers actions and undertakings of all Men, with the eye of a Philosopher, there is almost none which to me seems not vain and useless. Yet I am extremely satisfied with the Progress, which (as it seems to me) I have already made in the search of Truth, and do conceive such hopes for the future, That if among the employments of Men, purely Men, there is any solidly good, and of importance, I dare beleeve it is that which I have chosen: Yet it may be that I deceive my self, and perhaps it is but a little Copper and Glass which I take for Gold and Diamonds. I know how subject we are to mistake in those things which concern us, and how jealous we ought to be of the judgment of our friends, when it is in our favor. But I should willingly in this Discourse, trace out unto you the ways which I have followed, and represent therein my life, as in a Picture, to the end, that every one may judge thereof; and that learning from common Fame, what mens opinions are of it, I may finde a new means of instructing my self; which I shall add to those which I customarily make use of.

Neither is it my design to teach a Method which every Man ought to follow, for the good conduct of his reason; but only to shew after what manner I have endevoured to order mine own. Those who undertake to give precepts, ought to esteem themselves more able, then those to whom they give them, and are blame-worthy, if they fail in the least. But proposing this but as a History, or if you will have it so, but as a Fable; wherein amongst other examples, which may be imitated, we may perhaps find divers others which we may have reason to decline: I hope it will be profitable to some, without being hurtfull to any; and that the liberty I take will be gratefull to all.

I have been bred up to Letters from mine infancy; & because I was perswaded, that by their means a man might acquire a clear and certain knowledg of all that's usefull for this life, I was extremely desirous to learn them: But as soon as I had finish'd all the course of my Studies, at the end whereof Men are usually receiv'd amongst the rank of the learned. I wholly changed my opinion, for I found my self intangled in so many doubts and errors, that me thought I had made no other profit in seeking to instruct my self, but that I had the more discovered mine own ignorance. Yet I was in one of the most famous Schools in _Europe_; where I thought, if there were any on earth, there ought to have been learned Men. I had learnt all what others had learnt; even unsatisfied with the Sciences which were taught us, I had read over all Books (which I could possibly procure) treating of such as are held to be the rarest and the most curious. Withall, I knew the judgment others made of me; and I perceiv'd that I was no less esteem'd then my fellow Students, although there were some amongst them that were destin'd to fill our Masters rooms. And in fine, our age seem'd to me as flourishing and as fertile of good Wits, as any of the preceding, which made me take the liberty to judg of all other men by my self, and to think, That there was no such learning in the world, as formerly I had been made beleeve.

Yet did I continue the esteem I had of those exercises which are the employments of the Schools: I knew that Languages which are there learnt, are necessary for the understanding of ancient Writers, That the quaintness of Fables awakens the Minde; That the memorable actions in History raise it up, and that being read with discretion, they help to form the judgment. That the reading of good books, is like the conversation with the honestest persons of the past age, who were the Authors of them, and even a studyed conversation, wherein they discover to us the best only of their thoughts. That eloquence hath forces & beauties which are incomparable. That Poetry hath delicacies and sweets extremly ravishing; That the Mathematicks hath most subtile inventions, which very much conduce aswel to content the curious, as to facilitate all arts, and to lessen the labour of Men: That those
