René Descartes: Early Modern (1596–1650)



Meditation One

Of the Things of Which We May Doubt

1. Several years have now elapsed since I first became aware that I had accepted, even from my youth, many false opinions for true, and that consequently what I afterward based on such principles was highly doubtful; and from that time I was convinced of the necessity of undertaking once in my life to rid myself of all the opinions I had adopted, and of commencing anew the work of building from the foundation, if I desired to establish a firm and abiding superstructure in the sciences. But as this enterprise appeared to me to be one of great magnitude, I waited until I had attained an age so mature as to leave me no hope that at any stage of life more advanced I should be better able to execute my design. On this account, I have delayed so long that I should henceforth consider I was doing wrong were I still to consume in deliberation any of the time that now remains for action. To-day, then, since I have opportunely freed my mind from all cares [and am happily disturbed by no passions], and since I am in the secure possession of leisure in a peaceable retirement, I will at length apply myself earnestly and freely to the general overthrow of all my former opinions.

2. But, to this end, it will not be necessary for me to show that the whole of these are false—a point, perhaps, which I shall never reach; but as even now my reason convinces me that I ought not the less carefully to withhold belief from what is not entirely certain and indubitable, than from what is manifestly false, it will be sufficient to justify the rejection of the whole if I shall find in each some ground for doubt. Nor for this purpose will it be necessary even to deal with each belief individually, which would be truly an endless labor; but, as the removal from below of the foundation necessarily involves the downfall of the whole edifice, I will at once approach the criticism of the principles on which all my former beliefs rested.

3. All that I have, up to this moment, accepted as possessed of the highest truth and certainty, I received either from or through the senses. I observed, however, that these sometimes misled us; and it is the part of prudence not to place absolute confidence in that by which we have even once been deceived.

A hundred years ago G.K. Chesterton wrote that man’s reliance on human reason alone had wrongly created an inverse juxtaposition of cognitive humility and individual dogmatism. In plain talk, this means truth must be held with loose hands because it can never fully be known, but people should boldly stand firm as their own moral authority. Nonsense.

As Chesterton rightly said

Modesty has moved from the organ of ambition. Modesty has settled upon the organ of conviction; where it was never meant to be. A man was meant to be doubtful about himself, but undoubting about the truth; this has been exactly reversed.

Rather than relaying on that which is reasonable to a limited human mind, Chesterton says “The part he doubts is exactly the part he ought not to doubt—the Divine Reason.”

John Mark Reynolds said this in his book, The Great Books Reader:

Modernity gone wrong has isolated humanity and made human reason autonomous of (and dismissive toward) revelation. Descartes may not have made these errors himself, but the tendencies are there in his writings. The world he helped create also developed disrespect for human experience: if an idea could not be “proven,” then it was disreputable. The more chaotic elements of postmodern thought have been a natural counter-reaction.

Read his work critically, but not overly critically. If one wishes to abandon the modern, one cannot take for granted that one will continue to enjoy all of the good it has produced. One thing is certain: René Descartes is admirably clear, persuasive, and faithful in suggesting the direction he believes we should take.

Is Christianity reasonable?

The Beauty of This Immense Light


Thomas Ward

The Meditations of René Descartes is probably the most widely read philosophical text in the Western world. Not only is it rich and challenging, but it’s also a work of literary brilliance. Not since Augustine’s Confessions had there been a philosophical work so personal.

Written in the first-person singular, in a nontechnical idiom (for the most part), any reader can approach the work and begin immediately to grapple with weighty problems. But its brilliance as a piece of literature is most clearly evident in the way its ideas are reinforced through its literary form. In a first-person meditation, Descartes is articulating a philosophical position that places the individual thinker—the meditator—at the logical foundations of philosophical inquiry.

Descartes reserves a prominent role for God in his philosophy, but it might seem that the pride of place is actually reserved for the individual thinker attempting to reason his way out of his solitude, with God introduced merely to ensure that the reconstruction of knowledge can proceed. Indeed, the subsequent philosophical tradition has tended to characterize Descartes’s philosophy in just this way, with him as a reluctant theist. Many echo the sentiments of his contemporary Blaise Pascal, who said, “I cannot forgive Descartes; in all his philosophy he did his best to dispense with God.”

Like the Confessions, however, Meditations is a God-infused book. Most readers these days overlook this fact, tending to write off the more theological aspects and to focus on the meditator’s skeptical arguments and subjective outlook. This is unfair. A proper appreciation of Descartes demands we take his theological thought seriously.


So, how does God enter the philosophical picture? Descartes’s fundamental philosophical goal was to discover an absolutely certain foundation of knowledge, and he thought he’d made this discovery in one three-word Latin sentence:

Cogito, ergo sum; I think, therefore I am.

(Roughly the same thought is expressed in different terms in the Meditations; this version is found in Principles of Philosophy.) The idea is that you cannot doubt your own existence, because the act of doubting presupposes that there’s something doing the doubting—the doubter.

Dissatisfied with what he’d been taught at school, Descartes set out to question everything, rejecting each belief that wasn’t certain. In the First Meditation, he walks us through a gauntlet of skeptical arguments, offering reasons for doubting our beliefs in even the most ordinary and obvious things: that there’s a physical world, that you have a body, that other people exist, that God exists, and that 2 + 2 = 4. By the close, it seems skepticism has swept everything aside, that there is nothing but “inextricable darkness.”

However, in the Second Meditation, Descartes realizes there is one thing that simply cannot be doubted: that he exists.

From this single foundation of certainty, Descartes attempts a reconstruction of all our knowledge of the world and of God. Certain at least that he is, he wonders how, if he were the only existing thing, he should have an idea of a supremely perfect, infinite Being.

He first reasons that there is no way he himself could be the source of his idea of God, that God Himself must be and must have given Descartes the idea of Himself; in his beautiful portrayal, the idea of God is “the mark of the craftsman stamped on his work.”

So, Descartes’s world has gone from one to two; first him alone in the darkness, and now him together with God. From here he reflects on God’s nature, in particular His goodness. He reasons it would be inconsistent with God’s goodness that nearly all his beliefs should be utterly false; God, he says, is not a deceiver.

If we’re sufficiently careful in our pursuit of knowledge, then, we can be assured we will reach it. With this argument, Descartes reopens the door to the external world. If we restrict ourselves to believing only those things that we can “clearly and distinctly” perceive, we will not err in our judgment.


Perhaps now we can see, minimally, why Pascal’s critique may not be sufficiently charitable. There definitely is a sense in which the self comes before God in Descartes’s system, but there is equally, and arguably more importantly, a sense in which God is before everything else. Let me explain.

For Descartes, the knowledge of oneself comes before the knowledge of God. I don’t mean “before” in a temporal sense, the way we might think of a child gaining self-awareness before she becomes aware of God. I do mean that in an explanation of the justification of our beliefs, knowledge of God (and of the world God has created) follows knowledge of oneself.

In the course of writing Descartes not only uses the Cogito, ergo sum argument to support his other beliefs, he also discovers some of the external conditions that make possible the activity of meditating in the first place. Most significantly, he discovers that his existence and activity must be sustained from moment to moment by God’s continual conservation. Thus, for Descartes, the existence of oneself comes after the existence of God.

We might say that Descartes set out alone to discover God but learned that God was with him in the search.
