[pg/etext93/dcart10.txt]This work is one of the most influential in history. The famousphrase, "COGITO ERGO SUM" (I think, therefore I am) is a centraltheme. Descartes' beliefs on that dual nature of mind and body,and his emphasis on the role of doubt in all inquiry, formed thebasis for centuries of science and social thought.This etext was created by Ilana and Greg Newby.

And inthis it is not likely that all are mistaken the conviction is rather to beheld as testifying that the power of judging aright and of distinguishingtruth from error, which is properly what is called good sense or reason,is by nature equal in all men; and that the diversity of our opinions,consequently, does not arise from some being endowed with a larger shareof reason than others, but solely from this, that we conduct our thoughtsalong different ways, and do not fix our attention on the same objects.For to be possessed of a vigorous mind is not enough; the prime requisiteis rightly to apply it. The greatest minds, as they are capable of thehighest excellences, are open likewise to the greatest aberrations; andthose who travel very slowly may yet make far greater progress, providedthey keep always to the straight road, than those who, while they run,forsake it.For myself, I have never fancied my mind to be in any respect more perfectthan those of the generality; on the contrary, I have often wished that Iwere equal to some others in promptitude of thought, or in clearness anddistinctness of imagination, or in fullness and readiness of memory. Andbesides these, I know of no other qualities that contribute to theperfection of the mind; for as to the reason or sense, inasmuch as it isthat alone which constitutes us men, and distinguishes us from the brutes,I am disposed to believe that it is to be found complete in eachindividual; and on this point to adopt the common opinion of philosophers,who say that the difference of greater and less holds only among theaccidents, and not among the forms or natures of individuals of the samespecies.I will not hesitate, however, to avow my belief that it has been mysingular good fortune to have very early in life fallen in with certaintracks which have conducted me to considerations and maxims, of which Ihave formed a method that gives me the means, as I think, of graduallyaugmenting my knowledge, and of raising it by little and little to thehighest point which the mediocrity of my talents and the brief duration ofmy life will permit me to reach. For I have already reaped from it suchfruits that, although I have been accustomed to think lowly enough ofmyself, and although when I look with the eye of a philosopher at thevaried courses and pursuits of mankind at large, I find scarcely one whichdoes not appear in vain and useless, I nevertheless derive the highestsatisfaction from the progress I conceive myself to have already made inthe search after truth, and cannot help entertaining such expectations ofthe future as to believe that if, among the occupations of men as men, thereis any one really excellent and important, it is that which I have chosen.After all, it is possible I may be mistaken; and it is but a littlecopper and glass, perhaps, that I take for gold and diamonds. I know howvery liable we are to delusion in what relates to ourselves, and also howmuch the judgments of our friends are to be suspected when given in ourfavor. But I shall endeavor in this discourse to describe the paths Ihave followed, and to delineate my life as in a picture, in order thateach one may also be able to judge of them for himself, and that in thegeneral opinion entertained of them, as gathered from current report, Imyself may have a new help towards instruction to be added to those I havebeen in the habit of employing.My present design, then, is not to teach the method which each ought tofollow for the right conduct of his reason, but solely to describe the wayin which I have endeavored to conduct my own. They who set themselves togive precepts must of course regard themselves as possessed of greater skillthan those to whom they prescribe; and if they err in the slightest particular,they subject themselves to censure. But as this tract is put forth merelyas a history, or, if you will, as a tale, in which, amid some examples worthyof imitation, there will be found, perhaps, as many more which it wereadvisable not to follow, I hope it will prove useful to some without beinghurtful to any, and that my openness will find some favor with all.From my childhood, I have been familiar with letters; and as I was givento believe that by their help a clear and certain knowledge of all that isuseful in life might be acquired, I was ardently desirous of instruction.But as soon as I had finished the entire course of study, at the close ofwhich it is customary to be admitted into the order of the learned, Icompletely changed my opinion. For I found myself involved in so manydoubts and errors, that I was convinced I had advanced no farther in allmy attempts at learning, than the discovery at every turn of my ownignorance. And yet I was studying in one of the most celebrated schools inEurope, in which I thought there must be learned men, if such wereanywhere to be found. I had been taught all that others learned there;and not contented with the sciences actually taught us, I had, inaddition, read all the books that had fallen into my hands, treating ofsuch branches as are esteemed the most curious and rare. I knew thejudgment which others had formed of me; and I did not find that I wasconsidered inferior to my fellows, although there were among them some whowere already marked out to fill the places of our instructors. And, infine, our age appeared to me as flourishing, and as fertile in powerfulminds as any preceding one. I was thus led to take the liberty of judgingof all other men by myself, and of concluding that there was no science inexistence that was of such a nature as I had previously been given to believe.I still continued, however, to hold in esteem the studies of the schools.I was aware that the languages taught in them are necessary to theunderstanding of the writings of the ancients; that the grace of fablestirs the mind; that the memorable deeds of history elevate it; and, ifread with discretion, aid in forming the judgment; that the perusal of allexcellent books is, as it were, to interview with the noblest men of pastages, who have written them, and even a studied interview, in which arediscovered to us only their choicest thoughts; that eloquence hasincomparable force and beauty; that poesy has its ravishing graces anddelights; that in the mathematics there are many refined discoverieseminently suited to gratify the inquisitive, as well as further all thearts an lessen the labour of man; that numerous highly useful precepts andexhortations to virtue are contained in treatises on morals; that theologypoints out the path to heaven; that philosophy affords the means ofdiscoursing with an appearance of truth on all matters, and commands theadmiration of the more simple; that jurisprudence, medicine, and the othersciences, secure for their cultivators honors and riches; and, in fine,that it is useful to bestow some attention upon all, even upon thoseabounding the most in superstition and error, that we may be in a positionto determine their real value, and guard against being deceived.But I believed that I had already given sufficient time to languages, andlikewise to the reading of the writings of the ancients, to theirhistories and fables. For to hold converse with those of other ages andto travel, are almost the same thing. It is useful to know something ofthe manners of different nations, that we may be enabled to form a morecorrect judgment ...
