Disillusioned, we had to abandon the position of those who seek to give consolation the force of rational and logical truth, pretending to prove the rationality, or at any rate the non-irrationality, of consolation; and we had to abandon likewise the position of those who seek to give rational truth the force of consolation and of a motive for life. Neither the one nor the other of these positions satisfied us. The one is at variance with our reason, the other with our feeling. These two powers can never conclude peace and we must needs live by their war. We must make of this war, of war itself, the very condition of our spiritual life.

Neither does this high debate admit of that indecent and repugnant expedient which the more or less parliamentary type of politician has devised and dubbed "a formula of agreement," the property of which is to render it impossible for either side to claim to be victorious. There is no place here for a time-serving compromise. Perhaps a degenerate and cowardly reason might bring itself to propose some such formula of agreement, for in truth reason lives by formulas; but life, which cannot be formulated, life which lives and seeks to live for ever, does not submit to formulas. Its sole formula is: all or nothing. Feeling does not compound its differences with middle terms.

Initium sapientiæ timor Domini, it is said, meaning perhaps timor mortis, or it may be, timor vitæ, which is the same thing. Always it comes about that the beginning of wisdom is a fear.

Is it true to say of this saving scepticism which I am now going to discuss, that it is doubt? It is doubt, yes, but it is much more than doubt. Doubt is commonly something very cold, of very little vitalizing force, and above all something rather artificial, especially since Descartes degraded it to the function of a method. The conflict between reason and life is something more than a doubt. For doubt is easily resolved into a comic element.

The methodical doubt of Descartes is a comic doubt, a doubt purely theoretical and provisional—that is to say, the doubt of a man who acts as if he doubted without really doubting. And because it was a stove-excogitated doubt, the man who deduced that he existed from the fact that he thought did not approve of "those turbulent (brouillonnes) and restless persons who, being called neither by birth nor by fortune to the management of public affairs, are perpetually devising some new reformation," and he was pained by the suspicion that there might be something of this kind in his own writings. No, he, Descartes, proposed only to "reform his own thoughts and to build upon ground that was wholly his." And he resolved not to accept anything as true when he did not recognize it clearly to be so, and to make a clean sweep of all prejudices and received ideas, to the end that he might construct his intellectual habitation anew. But "as it is not enough, before beginning to rebuild one's dwelling-house, to pull it down and to furnish materials and architects, or to study architecture oneself ... but it is also necessary to be provided with some other wherein to lodge conveniently while the work is in progress," he framed for himself a provisional ethic—une morale de provision—the first law of which was to observe the customs of his country and to keep always to the religion in which, by the grace of God, he had been instructed from his infancy, governing himself in all things according to the most moderate opinions. Yes, exactly, a provisional religion and even a provisional God! And he chose the most moderate opinions "because these are always the most convenient for practice." But it is best to proceed no further.

This methodical or theoretical Cartesian doubt, this philosophical doubt excogitated in a stove, is not the doubt, is not the scepticism, is not the incertitude, that I am talking about here. No! This other doubt is a passionate doubt, it is the eternal conflict between reason and feeling, science and life, logic and biotic. For science destroys the concept of personality by reducing it to a complex in continual flux from moment to moment—that is to say, it destroys the very foundation of the spiritual and emotional life, which ranges itself unyieldingly against reason.

And this doubt cannot avail itself of any provisional ethic, but has to found its ethic, as we shall see, on the conflict itself, an ethic of battle, and itself has to serve as the foundation of religion. And it inhabits a house which is continually being demolished and which continually it has to rebuild. Without ceasing the will, I mean the will never to die, the spirit of unsubmissiveness to death, labours to build up the house of life, and without ceasing the keen blasts and stormy assaults of reason beat it down.

And more than this, in the concrete vital problem that concerns us, reason takes up no position whatever. In truth, it does something worse than deny the immortality of the soul—for that at any rate would be one solution—it refuses even to recognize the problem as our vital desire presents it to us. In the rational and logical sense of the term problem, there is no such problem. This question of the immortality of the soul, of the persistence of the individual consciousness, is not rational, it falls outside reason. As a problem, and whatever solution it may receive, it is irrational. Rationally even the very propounding of the problem lacks sense. The immortality of the soul is as unconceivable as, in all strictness, is its absolute mortality. For the purpose of explaining the world and existence—and such is the task of reason—it is not necessary that we should suppose that our soul is either mortal or immortal. The mere enunciation of the problem is, therefore, an irrationality.

Let us hear what our brother Kierkegaard has to say. "The danger of abstract thought is seen precisely in respect of the problem of existence, the difficulty of which it solves by going round it, afterwards boasting that it has completely explained it. It explains immortality in general, and it does so in a remarkable way by identifying it with eternity—with the eternity which is essentially the medium of thought. But with the immortality of each individually existing man, wherein precisely the difficulty lies, abstraction does not concern itself, is not interested in it. And yet the difficulty of existence lies just in the interest of the existing being—the man who exists is infinitely interested in existing. Abstract thought besteads immortality only in order that it may kill me as an individual being with an individual existence, and so make me immortal, pretty much in the same way as that famous physician in one of Holberg's plays, whose medicine, while it took away the patient's fever, took away his life at the same time. An abstract thinker, who refuses to disclose and admit the relation that exists between his abstract thought and the fact that he is an existing being, produces a comic impression upon us, however accomplished and distinguished he may be, for he runs the risk of ceasing to be a man. While an effective man, compounded of infinitude and finitude, owes his effectiveness precisely to the conjunction of these two elements and is infinitely interested in existing, an abstract thinker, similarly compounded, is a double being, a fantastical being, who lives in the pure being of abstraction, and at times presents the sorry figure of a professor who lays aside this abstract essence as he lays aside his walking-stick. When one reads the Life of a thinker of this kind—whose writings may be excellent—one trembles at the thought of what it is to be a man. And when one reads in his writings that thinking and being are the same thing, one thinks, remembering his life, that that being, which is identical with thinking, is not precisely the same thing as being a man" (Afsluttende uvidenskabelig Efterskrift, chap. iii.).

What intense passion—that is to say, what truth—there is in this bitter invective against Hegel, prototype of the rationalist!—for the rationalist takes away our fever by taking away our life, and promises us, instead of a concrete, an abstract immortality, as if the hunger for immortality that consumes us were an abstract and not a concrete hunger!
