[Dedicatory letter to the Sorbonne]
To those most learned and distinguished men, the Dean and Doctors of the sacred Faculty of Theology at Paris, from René Descartes.
I have a very good reason for offering this book to you, and I am confident that you will have an equally good reason for giving it your protection once you understand the principle behind my undertaking; so much so, that my best way of commending it to you will be to tell you briefly of the goal which I shall be aiming at in the book.
I have always thought that two topics – namely God and the soul – are prime examples of subjects where demonstrative proofs ought to be given with the aid of philosophy rather than theology. For us who are believers, it is enough to accept on faith that the human soul does not die with the body, and that God exists; but in the case of unbelievers, it seems that there is no religion, and practically no moral virtue, that they can be persuaded to adopt until these two truths are proved to them by natural reason. And since in this life the rewards offered to vice are often greater than the rewards of virtue, few people would prefer what is right to what is expedient if they did not fear God or have the expectation of an after-life. It is of course quite true that we must believe in the existence of God because it is a doctrine of Holy Scripture, and conversely, that we must believe Holy Scripture because it comes from God; for since faith is the gift of God, he who gives us grace to believe other things can also give us grace to believe that he exists. But this argument cannot be put to unbelievers because they would judge it to be circular. Moreover, I have noticed both that you and all other theologians a**ert that the existence of God is capable of proof by natural reason, and also that the inference from Holy Scripture is that the knowledge of God is easier to acquire than the knowledge we have of many created things – so easy, indeed, that those who do not acquire it are at fault. This is clear from the pa**age in the Book of Wisdom, Chapter 13: ‘Howbeit they are not to be excused for if their knowledge was so great that they could value this world, why did they not rather find out the Lord thereof?' And in Romans, Chapter 1 it is said that they are ‘without excuse'. And in the same place, in the pa**age ‘that which is known of God is manifest in them', we seem to be told that everything that may be known of God can be demonstrated by reasoning which has no other source but our own mind. Hence I thought it was quite proper for me to inquire how this may be, and how God may be more easily and more certainly known than the things of this world.
As regards the soul, many people have considered that it is not easy to discover its nature, and some have even had the audacity to a**ert that, as far as human reasoning goes, there are persuasive grounds for holding that the soul dies along with the body and that the opposite view is based on faith alone. But in its eighth session the Lateran Council held under Leo X condemned those who take this position, and expressly enjoined Christian philosophers to refute their arguments and use all their powers to establish the truth; so I have not hesitated to attempt this task as well.
In addition, I know that the only reason why many irreligious people are unwilling to believe that God exists and that the human mind is distinct from the body is the alleged fact that no one has hitherto been able to demonstrate these points. Now I completely disagree with this: I think that when properly understood almost all the arguments that have been put forward on these issues by the great men have the force of demonstrations, and I am convinced that it is scarcely possible to provide any arguments which have not already been produced by someone else. Nevertheless, I think there can be no more useful service to be rendered in philosophy than to conduct a careful search, once and for all, for the best of these arguments, and to set them out so precisely and clearly as to produce for the future a general agreement that they amount to demonstrative proofs. And finally, I was strongly pressed to undertake this task by several people who knew that I had developed a method for resolving certain difficulties in the sciences – not a new method (for nothing is older than the truth), but one which they had seen me use with some success in other areas; and I therefore thought it my duty to make some attempt to apply it to the matter in hand.
The present treatise contains everything that I have been able to accomplish in this area. Not that I have attempted to collect here all the different arguments that could be put forward to establish the same results, for this does not seem worthwhile except in cases where no single argument is regarded as sufficiently reliable. What I have done is to take merely the principal and most important arguments and develop them in such a way that I would now venture to put them forward as very certain and evident demonstrations. I will add that these proofs are of such a kind that I reckon they leave no room for the possibility that the human mind will ever discover better ones. The vital importance of the cause and the glory of God, to which the entire undertaking is directed, here compel me to speak somewhat more freely about my own achievements than is my custom. But although I regard the proofs as quite certain and evident, I cannot therefore persuade myself that they are suitable to be grasped by everyone. In geometry there are many writings left by Archimedes, Apollonius, Pappus, and others which are accepted by everyone as evident and certain because they contain absolutely nothing that is not very easy to understand when considered on its own, and each step fits in precisely with what has gone before; yet because they are somewhat long, and demand a very attentive reader, it is only comparatively few people who understand them. In the same way, although the proofs I employ here are in my view as certain and evident as the proofs of geometry, if not more so, it will, I fear, be impossible for many people to achieve an adequate perceptions of them, both because they are rather long and some depend on others, and also, above all, because they require a mind which is completely free from preconceived opinions and which can easily detach itself from involvement with the senses. Moreover, people who have an aptitude for metaphysical studies are certainly not to be found in the world in any greater numbers than those who have an aptitude for geometry. What is more, there is the difference that in geometry everyone has been taught to accept that as a rule no proposition is put forward in a book without there being a conclusive demonstrations available; so inexperienced students make the mistake of accepting what is false, in their desire to appear to understand it, more often than they make the mistake of rejecting what is true. In philosophy, by contrast, the belief is that everything can be argued either way; so few people pursue the truth, while the great majority build up their reputation for ingenuity by boldly attacking whatever is most sound.
Hence, whatever the quality of my arguments may be, because they have to do with philosophy I do not expect they will enable me to achieve any very worthwhile results unless you come to my aid by granting me your patronage. The reputation of your Faculty is so firmly fixed in the minds of all, and the name of the Sorbonne has such authority that, with the exception of the Sacred Councils, no institution carries more weight than yours in matters of faith; while as regards human philosophy, you are thought of as second to none, both for insight and soundness and also for integrity and wisdom of your pronouncements. Because of this, the results of your careful attention to this book, if you deigned to give it, would be threefold. First, the errors in it would be corrected – for when I remember not only that I am a human being, but above all that I am an ignorant one, I cannot claim it is free of mistakes. Secondly, any pa**ages which are defective, or insufficiently developed or requiring further explanation, would be supplemented, completed and clarified, either by yourselves or by me after you have given me your advice. And lastly, once the arguments in the book proving that God exists and that the mind is distinct from the body have been brought, as I am sure they can be, to such a pitch of clarity that they are fit to be regarded as very exact demonstrations, you may be willing to declare as much, and make a public statement to that effect. If all this were to happen, I do not doubt that all the errors which have every existed on these subjects would soon be eradicated from the minds of men. In the case of all those who share your intelligence and learning, the truth itself will readily ensure that they subscribe to your opinion. As for the atheists, who are generally poses rather than people of real intelligence or learning, your authority will induce them to lay aside the spirit of the contradiction; and, since they know that the arguments are regarded as demonstrations by all who are intellectually gifted, they may even go so far as to defend them, rather than appear not to understand them. And finally, everyone else will confidently go along with so many declarations of a**ent, and there will be no one left in the world who will dare to call into doubt either the existence of God or the real distinction between the human soul and body. The great advantage that this would bring is something which you, in your singular wisdom, are in better position to evaluate than anyone; and it would ill become me to spend any more time commending the cause of God and religion to you, who have always been the greatest tower of strength to the Catholic Church.
[Preface to the reader]
I briefly touched on the topics of God and the human mind in my Discourse on the method of rightly conducting reason and seeking the truth in the sciences, which was published in French in 1637. My purpose there was not to provide a full treatment, but merely to offer a sample, and learn from the views of my readers how I should handle these topics at a later date. The issues seemed to me of such great importance that I considered they ought to be dealt with more than once; and the route which I follow in explaining them is so untrodden and so remote from the normal way, that I thought it would not be helpful to give a full account of it in a book written in French and designed to be read by all and sundry, in case weaker intellects might believe that they ought to set out on the same path.
In the Discourse I asked anyone who found anything worth criticizing in what I had written to be kind enough to point it out to me. In the case of my remarks concerning God and the soul, only two objections worth mentioning were put to me, which I shall now briefly answer before embarking on a more precise elucidation of these topics.
The first objection is this. From the fact that the human mind, when directed towards itself, does not perceive itself to be anything other than a thinking thing, it does not follow that its nature or essence consists only in its being a thinking thing, where the word ‘only' excludes everything else that could be said to belong to the nature of the soul. My answer to this objection is that in that pa**age it was not my intention to make those exclusions in an order corresponding to the actual truth of the matter (which I was not dealing with at that stage) but merely in an order corresponding to my own perception. So the sense of the pa**age was hat I was aware of nothing at all that I knew belonged to my essence, except that I was a thinking thing, or a thing possessing within itself the faulty of thinking. I shall, however, show below how it follows from the fact that I am aware of nothing else belonging to my essence, that nothing else does in fact belong to it.
The second objection is this. From the fact that I have within me an idea of a thing more perfect than myself, it does not follow that the idea itself is more perfect than me, still less that what is represented by the idea exists. My reply is that there is an ambiguity here in the word ‘idea'. ‘Idea” can be taken materially, as an operation of the intellect, in which case it cannot be said to be more perfect than me. Alternatively, it can be taken objectively, as the thing represented by that operation; and this thing, even if it is not regarded as existing outside the intellect, can still, in virtue of its essence, be more perfect than myself. As to how, from the mere fact that there is within me an idea of something more perfect than me, it follows that this thing really exists, this is something which will be fully explained below.
Apart from these objections, there are two fairly lengthy essays which I have looked at, but these did not attack my reasoning on these matters so much as my conclusions, and employed arguments lifted from the standard sources of the atheists. But arguments of this sort can carry no weight with those who understand my reasoning. Moreover, the judgment of many people is so silly and weak that, once they have accepted a view, they continue to believe it, however false and irrational it may be, in preference to a true and well-grounded refutation which they hear subsequently. So I do not wish to reply to shuch arguments here, if only to avoid having to state them. I will only make the general point that all the objections commonly tossed around by atheists to attack the existence of God invariably depend either on attributing human feelings to God or on arrogantly supposing our own minds to be so powerful and wise that we can attempt to grasp and set limits to what God can or should perform. So, provided only that we remember that our minds must be regarded as finite, while God is infinite and beyond our comprehension, such objections will not cause us any difficulty.
But now that I have, after a fashion, taken an initial sample of people's opinions, I am again tackling the same questions concerning God and the human mind; and this time I am also going to deal with the foundations of First Philosophy in its entirety. But I do not expect any popular approval, or indeed any great crowd of readers. On the contrary I would not urge anyone to read this book except those who are able and willing to meditate seriously with me, and to withdraw their minds from the senses and from al preconceived opinions. Such readers, as I well know, are few and far between. Those who do not bother to grasp the proper order of my arguments and the connection between them, but merely try to carp at individual sentences, as is the fashion, will not get much benefit from reading this book. They may well find an opportunity to quibble in many places, but it will not be easy for them to produce objections which as telling or worth replying to.
But I certainly do not promise to satisfy my other readers straightaway on all points, and I am not so presumptuous as to believe that I am capable of foreseeing all the difficulties which anyone may find. So first of all, in the Meditations, I will set out the very thougths which have enabled me, in my view, to arrive at a certain and evident knowledge of the truth, so that I can find out whether the same arguments which have convinced me will enable me to convince others. Next, I will reply to the objections of various men of outstanding intellect and scholarship who had these Meditations sent to them for scrutiny before they went to press. For the objections they raised were so many and so varied that I would venture to hope that it will be hard for anyone else to think of any point – at least of any importance – which these critics have not touched on. I therefore ask my readers not to pa** judgment on the Meditations until they have been kind enough to read through all these objections and my replies to them.
