I thank you, my dear friend, for your kind letter. It afforded me great pleasure and comfort during this dreary vacation, which I am spending in the most painful isolation you can possibly conceive. There is not a human being to whom I can open my heart, nor, what is still worse, with whom I can indulge in conversations which, however commonplace, repose the mind and satisfy one’s craving for company. One can be much more secluded in Paris than in the midst of the desert, as I am now realizing for myself. Society does not consist in seeing one’s fellow-men, but in holding with them some of those communications which remind one that one is not alone in the world. At times, when I happen to be mixed up in the crowds which fill our streets, I fancy that I am surrounded by trees walking. The effect is precisely the same. When I think of the perfect happiness which used to be my lot at this season of the year, a great sadness comes over me, especially when I remember that I have said an everlasting farewell to these blissful days. I don’t know whether you are like me, but there is nothing more painful to me than to have to say, even in respect to the most trifling matter, “It is all over, for once and all.” What must I suffer, then, when I have to say this of the only pleasures which in my heart I cared for? But what can be done? I do not repent anything, and the suffering induced in the cause of duty brings with it a joy far greater than those which may have been sacrificed to it. I thank God for having given me in you one who understands me so well that I have no need even to lay bare the state of my heart to him. Yes, it is one of my chief sorrows to think that the persons whose approbation would be the most precious to me must blame me and condemn me. Fortunately that will not prevent them from pitying and loving me.

I am not one of those who are constantly preaching tolerance to the orthodox; this is the cause of numberless sophisms for the superficial minds in both camps. It is unfair upon Catholicism to dress it up according to our modern ideas, in addition to which this can only be done by verbal concessions which denote bad faith or frivolity. All or nothing, the Neo-Catholics are the most foolish of any.

No, my dear friend, do not scruple to tell me that I am in this state through my own fault; I feel sure that you must think so. It is of course painful for me to think that perhaps as much as half of the enlightened portion of humanity would tell me that I am hateful in the sight of God, and to use the old Christian phraseology, which is the true one, that if death overtook me, I should be immediately damned. This is terrible, and it used to make me tremble, for somehow or other the thought of death always seems to me very close at hand. But I have got hardened to it, and I can only wish to the orthodox a peace of mind equal to that which I enjoy. I may safely say that since I accomplished my sacrifice, amid outward sorrows greater than would be believed, and which, from perhaps a false feeling of delicacy, I have concealed from every one, I have tasted a peace which was unknown to me during periods of my life to all appearance more serene. You must not accept, my dear friend, certain generalities in regard to happiness which are very erroneous, and all of which assume that one cannot be happy except by consistency, and with a perfectly harmonized intellectual system. At this rate, no one would be happy, or only those whose limited intelligence could not rise to the conception of problems or of doubt. It is fortunately not so; and we owe our happiness to a piece of inconsistency, and to a certain turn of the wheel which causes us to take patiently what with another turn of the wheel would be absolute torture. I imagine that you must have felt this. There is a sort of inward debate going on within us with regard to happiness, and by it we are inevitably influenced in the way we take a certain thing; for there is no one who will deny that he contains within himself a thousand germs which might render him absolutely wretched. The question is whether he will allow them free course, or whether he will abstract himself from them. We are only happy on the sly, my dear friend, but what is to be done? Happiness is not so sacred a thing that it should only be accepted when derived from perfect reason.

You will perhaps think it strange that, not believing in Christianity, I can feel so much at ease. This would be singular if I still had doubts, but if I must tell you the whole truth, I will confess that I have almost got beyond the doubting stage. Explain to me how you manage to believe. My dear friend, it is too late for me to exclaim to you. “Take care.” If you were not what you are, I should throw myself at your feet, and implore of you to declare whether you felt that you could swear that you would not alter your views at any period of your existence.... Think what is involved in swearing as to one’s future thoughts!... I am very sorry that our friend A—— is definitely bound to the Church, for I feel sure that if he has not already doubted he will do so. We shall see in another twenty years. I hardly know what I am saying to you, but I cannot help wishing with St. Paul, that “all were such as I am,” thankful that I have no need to add “except these bonds.” With respect to the bonds which held me before, I do not regret them. Philosophy bids us say, Dominus pars.

When I was going up to the altar to receive the tonsure, I was already terribly exercised by doubt, but I was forced onward, and I was told that it was always well to obey. I went forward therefore, but God is my witness, that my inmost thought and the vow which I made to myself, was that I would take for my part the truth which is the hidden God, that I would devote myself to its research, renouncing all that is profane, or that is calculated to make us deviate from the holy and divine goal to which nature calls us. This was my resolve, and an inward voice told me that I should never repent me of my promise. And I do not repent of it, my dear friend, and I am ever repeating the soothing words Dominus pars, and I believe that I am not less agreeable to God or faithful to my promise, than he who does not scruple to pronounce them with a vain heart, and a frivolous mind. They will never be a reproach to me until, prostituting my thought to vulgar objects, I devote my life to one of those gross and commonplace aims which suffice for the profane, and until I prefer gross and material pleasures to the sacred pursuit of the beautiful and the true. Until that time arrives, I shall recall with anything but regret the day on which I pronounced these words.

Man can never be sure enough of his thoughts to swear fidelity to such and such a system which for the time he regards as true. All that he can do is to devote himself to the service of the truth, whatever it may be, and dispose his heart to follow it wherever he believes that he can see it, at no matter how great a sacrifice.

I write you these lines in haste, and with my head full of the by no means agreeable work which I am doing for my examination, so you must excuse the want of order in my ideas. I shall expect a long letter from you which will have on me the effect of water on a thirsty land.

PARIS, September 11th, 1846.

I wish that I could comment on each line of your letter which I received an hour ago, and communicate the many different reflections which it awakens in me. But I am so hard at work that this is impossible. I cannot refrain, however, from committing to paper the principal points upon which it is important that we should come to an immediate understanding.

It grieved me very much to read that there was henceforward a gulf fixed between your beliefs and mine. It is not so—we believe the same things; you in one form, I in another. The orthodox are too concrete, they set so much store by facts and by mere trifles. Remember the definition given of Christianity by the Proconsul (ni fallor) spoken of in the Acts of the Apostles, “Touching one Jesus, which was dead, and whom Paul declared to be alive.” Be upon your guard against reducing the question to such paltry terms. Now I ask of you can the belief in any special fact, or rather the manner of appreciating and criticising this fact, affect a man’s moral worth? Jesus was much more of a philosopher in this respect than the Church.
