The peace of fact is not the peace of principle. There are indeed two happinesses, that of nature and that of conquest—two equilibria, that of Greece and that of Nazareth—two kingdoms, that of the natural man and that of the regenerate man.

Later. (Scheveningen).—Why do doctors so often make mistakes? Because they are not sufficiently individual in their diagnoses or their treatment. They class a sick man under some given department of their nosology, whereas every invalid is really a special case, a unique example. How is it possible that so coarse a method of sifting should produce judicious therapeutics? Every illness is a factor simple or complex, which is multiplied by a second factor, invariably complex—the individual, that is to say, who is suffering from it, so that the result is a special problem, demanding a special solution, the more so the greater the remoteness of the patient from childhood or from country life.

The principal grievance which I have against the doctors is that they neglect the real problem, which is to seize the unity of the individual who claims their care. Their methods of investigation are far too elementary; a doctor who does not read you to the bottom is ignorant of essentials. To me the ideal doctor would be a man endowed with profound knowledge of life and of the soul, intuitively divining any suffering or disorder of whatever kind, and restoring peace by his mere presence. Such a doctor is possible, but the greater number of them lack the higher and inner life, they know nothing of the transcendent laboratories of nature; they seem to me superficial, profane, strangers to divine things, destitute of intuition and sympathy. The model doctor should be at once a genius, a saint, a man of God.

September 11, 1873. (Amsterdam).—The doctor has just gone. He says I have fever about me, and does not think that I can start for another three days without imprudence. I dare not write to my Genevese friends and tell them that I am coming back from the sea in a radically worse state of strength and throat than when I went there, and that I have only wasted my time, my trouble, my money, and my hopes....

This contradictory double fact—on the one side an eager hopefulness springing up afresh after all disappointments, and on the other an experience almost invariably unfavorable—can be explained like all illusions by the whim of nature, which either wills us to be deceived or wills us to act as if we were so.

Skepticism is the wiser course, but in delivering us from error it tends to paralyze life. Maturity of mind consists in taking part in the prescribed game as seriously as though one believed in it. Good-humored compliance, tempered by a smile, is, on the whole, the best line to take; one lends one’s self to an optical illusion, and the voluntary concession has an air of liberty. Once imprisoned in existence, we must submit to its laws with a good grace; to rebel against it only ends in impotent rage, when once we have denied ourselves the solution of suicide.

Humility and submission, or the religious point of view; clear-eyed indulgence with a touch of irony, or the point of view of worldly wisdom—these two attitudes are possible. The second is sufficient for the minor ills of life, the other is perhaps necessary in the greater ones. The pessimism of Schopenhauer supposes at least health and intellect as means of enduring the rest of life. But optimism either of the stoical or the Christian sort is needed to make it possible for us to bear the worst sufferings of flesh, heart and soul. If we are to escape the grip of despair, we must believe either that the whole of things at least is good, or that grief is a fatherly grace, a purifying trial.

There can be no doubt that the idea of a happy immortality, serving as a harbor of refuge from the tempests of this mortal existence, and rewarding the fidelity, the patience, the submission, and the courage of the travelers on life’s sea—there can be no doubt that this idea, the strength of so many generations, and the faith of the church, carries with it inexpressible consolation to those who are wearied, burdened, and tormented by pain and suffering. To feel one’s self individually cared for and protected by God gives a special dignity and beauty to life. Monotheism lightens the struggle for existence. But does the study of nature allow of the maintenance of those local revelations which are called Mosaism, Christianity, Islamism? These religions founded upon an infantine cosmogony, and upon a chimerical history of humanity, can they bear confronting with modern astronomy and geology? The present mode of escape, which consists in trying to satisfy the claims of both science and faith—of the science which contradicts all the ancient beliefs, and the faith which, in the case of things that are beyond nature and incapable of verification, affirms them on her own responsibility only—this mode of escape cannot last forever. Every fresh cosmical conception demands a religion which corresponds to it. Our age of transition stands bewildered between the two incompatible methods, the scientific method and the religious method, and between the two certitudes, which contradict each other.

Surely the reconciliation of the two must be sought for in the moral law, which is also a fact, and every step of which requires for its explanation another cosmos than the cosmos of necessity. Who knows if necessity is not a particular case of liberty, and its condition? Who knows if nature is not a laboratory for the fabrication of thinking beings who are ultimately to become free creatures? Biology protests, and indeed the supposed existence of souls, independently of time, space, and matter, is a fiction of faith, less logical than the Platonic dogma. But the question remains open. We may eliminate the idea of purpose from nature, yet, as the guiding conception of the highest being of our planet, it is a fact, and a fact which postulates a meaning in the history of the universe.

My thought is straying in vague paths: why? because I have no creed. All my studies end in notes of interrogation, and that I may not draw premature or arbitrary conclusions I draw none.
