The Penseés are a series of aphorisms or reflections, varying in length from a single sentence to more than twenty paragraphs, and numbering 923 in all. They are divided into thirteen sections, on such topics as "The Misery of Man without God," "Morality and Doctrine," and "The Fundamentals of the Christian Religion," with an appended fourteenth section of "Polemical Fragments," addressing the controversy between the Jesuits and the Jansenists.
Pascal attacks those philosophers who teach the goodness of human nature, and who see the highest good as the good to be found within ourselves, thereby placing us on an equal level with God. He argues that human nature has been corrupted by original sin. We're all born into sin, and we're obligated to resist or overcome it. He therefore condemns self-love (amour-propre), insofar as it reflects self-will rather than divine will, and insofar as it reflects love of self rather than love of God. He says that we can be blinded by self-love and by the instinct to place ourselves on an equal level with God (492). Indeed, we're so full of faults and imperfections that it's difficult to understand how we can feel such love for ourselves, given that we don't often feel the same kind of love for others (100).
Since we're often blinded by self-love and self-will, the nature of God is largely hidden from us. Just as God may be infinitely knowing, God may be infinitely incomprehensible to us. The fact that there are many other religions besides Christianity is also a sign that God's nature may be hidden from us. If God's nature were apparent and manifest, then there might be only one religion that humanity would feel called to follow (585).
However, Pascal also says that God is within us. The kingdom of God is within us, just as the universal good (le bien universel) is within us (485). But the universal good is to be found within us only insofar as God is to be found within us. Thus, "Happiness is neither without us nor within us. It is in God, both without us and within us" (465).1 Jesus Christ the Redeemer can be found within us, and can be found within all persons (785).
Pascal affirms the centrality of Christ to our knowledge of God. "Not only do we know God by Jesus Christ alone, but we know ourselves only by Jesus Christ...Apart from Jesus Christ, we do not know what is our life, nor our death, nor God, nor ourselves" (547).2 "It is not only impossible but useless to know God without Jesus Christ" ("Il n'est seulement impossible, mais inutile de connaître Dieu sans Jesus-Christ," 548).3
Reason (la raison) and feeling (le sentiment) may be seen as competing impulses in human nature. Reason may act methodically and deliberately, while feeling may act quickly and spontaneously (252). Faith is to be found in feeling, since reason ultimately can't prove the truths of faith and religion. "If we must not act except on certainty," says Pascal, then "we ought not to act on religion, for it is not certain. But...there is more certainty in religion than there is as to whether we may see tomorrow" (234).4 We should therefore avoid both the extreme of depending on reason alone and the extreme of depending on intuition or feeling alone (253).
Faith is a gift from God, rather than a gift from reasoning (279). However, faith isn't contrary to reason, and it doesn't call us to disobey reason. Indeed, "Reason commands us far more imperiously than a master, for in disobeying the one we are unfortunate, but in disobeying the other we are fools," (345).5 Having faith doesn't mean being blind to reason or to the evidence of sensory experience. Faith tells us what we can't confirm by sensory experience, but it doesn't contradict what we can confirm by sensory experience (265).
Reason tells us when we should submit to feeling. Indeed, reason tells us that there are an infinity of things that surpass our understanding, and that there are matters that can only be resolved by faith or feeling. "Reason would never submit if it did not judge that there are occasions on which it ought to submit. It is then right for it to submit when it judges that it ought to submit" (270).6 Thus, "There is nothing so conformable to reason as this disavowal of reason" (272),7 and "All our reasoning [therefore] reduces itself to yielding to feeling" (274).8
Pascal also argues that it is the heart and not the faculty of reasoning (raisonnement) that experiences God. "This, then, is faith, God felt by the heart, not by reason" (278).9 The heart has its own reasons for feeling, which can't be known solely by the intellect (277, 283). Thus, we can know truth not only by reason, but also by the heart (282). The heart can provide access to truth, just as reason can provide access to truth.
Pascal argues that even if we can't prove that God exists, we can still choose whether to believe or disbelieve in God's existence by weighing the potential gains or losses to be obtained from making either of these two choices. This is known as Pascal's wager--the decision to affirm or deny the existence of God (233). Practically speaking, we can't merely sit on the fence and be skeptical or agnostic. We have to make a choice, and Pascal's argument for affirming the existence of God is that we have much more to gain by believing than by disbelieving in God's existence.
