It is true that there are people who assert that reason suffices them, and they counsel us not to seek to penetrate into the impenetrable. But of those who say that they have no need of any faith in eternal personal life in order to find incentives to living and motives for action, I know not well how to think. A man blind from birth may also assure us that he feels no great desire to enjoy the world of sight nor suffers any great anguish from not having enjoyed it, and we must needs believe him, for nihil volitum quin præcognitum, nothing can be willed that is not previously known. But I cannot be persuaded that he who has once in his life, either in his youth or at some other point of time, cherished the belief in the immortality of the soul, will ever find peace without it. And this kind of blindness from birth is scarcely possible among men, except by a strange aberration. And the merely and exclusively rational man is an aberration and nothing but an aberration.
I do not know why so many people were scandalized, or pretended to be scandalized, when Brunetière proclaimed once again the bankruptcy of science. For science, in so far as it is a substitute for religion, and reason, in so far as it is a substitute for faith, have always foundered. Science will be able to satisfy in an increasing measure, and in fact does satisfy, our increasing logical and intellectual needs, our desire to know and understand the truth; but science does not satisfy the needs of our heart and our will, our hunger for immortality—far from satisfying it, it contradicts it. Rational life and truth stand in opposition to one another. And can it be that there is any other truth than rational truth?
It must remain established, therefore, that reason, human reason, within its limits not only does not prove rationally that the soul is immortal and that the human consciousness is through all the ages indestructible, but that it proves rather—within its limits, I repeat—that the individual consciousness cannot persist after the death of the physical organism upon which it depends. And these limits, within which I say that human reason proves this, are the limits of rationality, of what we know by demonstration. Beyond these limits is the irrational, which is all the same whether it be called the super-rational or the infra-rational or the contra-rational. Beyond these limits is the absurd of Tertullian, the impossible of the certum est, quia impossible est. And this absurd can only base itself upon the most absolute incertitude.
The vital longing for human immortality, therefore, finds no rational confirmation, nor does reason give us any incentive or consolation for living or give to life itself any real finality. But here, in the depths of the abyss, the despair of the heart and the will and the scepticism of reason meet face to face and embrace fraternally. And it will be from this embrace, a tragic, that is to say a profoundly loving, embrace, that the fountain of life will flow, a life earnest and terrible. Scepticism, uncertainty—the ultimate position at which reason arrives by practising its analysis upon itself, upon its own validity—is the foundation upon which the despair of the vital sense must build its hope.
Disillusioned, we have had to abandon the position of those who seek to convert rational and logical truth into consolation, pretending to prove the rationality, or at any rate the non-irrationality, of consolation; and we have had to abandon likewise the position of those who seek to convert consolation and motives for living into rational truth. Neither of these positions satisfies us. The one is at variance with our reason, the other with our feeling. Peace between these two powers is impossible and we must live by their war. We must make of this war, of war itself, the condition of our spiritual life.
Faith in immortality is irrational. And nevertheless, faith, life and reason have mutual need of one another. This vital longing is not properly a problem, cannot be formulated in propositions capable of rational discussion; but it announces itself in us as hunger announces itself. Neither can the wolf that throws itself upon its prey to devour it or upon the she-wolf to fecundate her, enunciate its impulse rationally and as a logical problem. Reason and faith are two enemies neither of which can maintain itself without the other. The irrational demands to be rationalized and reason alone can operate on the irrational. They are compelled to seek mutual support and association. But association in conflict, for conflict is a mode of association.
There is no possible permanent position of agreement and harmony between reason and life, between philosophy and religion. And the tragic history of human thought is simply the history of a struggle between reason and life—reason bent on rationalizing life and making it resign itself to the inevitable, to mortality; life bent on vitalizing reason and forcing it to serve as a support for its vital desires. And this is the history of philosophy, inseparable from the history of religion.
Our sense of the world, of objective reality, is necessarily subjective, human, anthropomorphic. And vitalism will always rise up against rationalism, the will will always stand up against reason. Hence the rhythm of the history of philosophy and the alternation of periods in which life imposes itself, giving birth to spiritual forms, with periods in which reason imposes itself, giving birth to materialistic forms, although both of these classes of forms of belief may disguise themselves under other names. Neither reason nor life ever acknowledges itself vanquished.
No doubt it will be said that life ought to submit to reason and to this we shall reply that nothing ought to be done that cannot be done, and life cannot submit to reason. “Ought, therefore can,” some Kantian will retort. To which we shall demur: “Cannot, therefore ought not.” And life cannot submit to reason, because the end of life is living and not understanding.
There is always someone who will tell us of the religious duty of resigning ourselves to mortality. This is indeed the very summit of aberration and insincerity. And over against sincerity will be set the opposing ideal of veracity. Be it so, and yet it is quite possible to reconcile the two. Veracity, respect for what I believe to be rational, for what we call truth in the logical sense, moves me to affirm that the immortality of the individual soul is a logical contradiction, is something not only irrational but contra-rational; but sincerity leads me to affirm also that I do not resign myself to this former affirmation and that I protest against its validity. What I feel is a truth, as much a truth at any rate as what I see, touch, hear, and what is demonstrated to me—I believe that it is even more of a truth—and sincerity obliges me not to hide my feelings.
