This frame of mind, however, was crossed by another. The religious transformation in my mind could not remain clear and unmuddied, placed as I was in a society furrowed through and through by different religious currents, issued as I was from the European races that for thousands of years had been ploughed by religious ideas. All the atavism, all the spectral repetition of the thoughts and ideas of the past that can lie dormant in the mind of the individual, leaped to the reinforcement of the harrowing religious impressions which came to me from without.
It was not the attitude of my friends that impressed me. All my more intimate friends were orthodox Christians, but the attempts which various ones, amongst them Julius Lange, and Jens Paludan-Müller, had made to convert me had glanced off from my much more advanced thought without making any impression. I was made of much harder metal than they, and their attempts to alter my way of thinking did not penetrate beyond my hide. To set my mind in vibration, there was needed a brain that I felt superior to my own; and I did not find it in them. I found it in the philosophical and religious writings of Sören Kierkegaard, in such works, for instance, as Sickness unto Death.
The struggle within me began, faintly, as I approached my nineteenth year. My point of departure was this: one thing seemed to me requisite, to live in and for The Idea, as the expression for the highest at that time was. All that rose up inimical to The Idea or Ideal merited to be lashed with scorn or felled with indignation. And one day I penned this outburst: "Heine wept over Don Quixote. Yes, he was right. I could weep tears of blood when I think of the book." But the first thing needed was to acquire a clear conception of what must be understood by the Ideal. Heiberg had regarded the uneducated as those devoid of ideals. But I was quite sure myself that education afforded no criterion. And I could find no other criterion of devotion to the Ideal than a willingness to make sacrifices. If, I said, I prove myself less self-sacrificing than any one of the wretches I am fighting, I shall myself incur well-merited scorn. But if self-sacrifice were the criterion, then Jesus, according to the teachings of tradition, was the Ideal, for who as self-sacrificing as He?
This was an inclined plane leading to the Christian spiritual life, and a year later, when I was nearly twenty, I had proceeded so far on this plane that I felt myself in all essentials in agreement with the Christian mode of feeling, inasmuch as my life was ascetic, and my searching, striving, incessantly working mind, not only found repose, but rapture, in prayer, and was elated and fired at the idea of being protected and helped by "God."
But just as I was about to complete my twentieth year, the storm broke out over again, and during the whole of the ensuing six months raged with unintermittent violence. Was I, at this stage of my development, a Christian or not? And if not, was it my duty to become a Christian?
The first thought that arose was this: It is a great effort, a constant effort, sometimes a minutely recurring effort, to attain moral mastery over one's self, and though this certainly need not bring with it a feeling of self-satisfaction, much less ought to do so, it does bring with it a recognition of the value of this self-mastery. How strange, then, that Christianity, which commands its attainment, at the same time declares it to be a matter of indifference to the revealed God whether a man has lived morally or not, since Faith or lack of Faith is the one condition upon which so-called Salvation depends!
The next thought was this: It is only in the writings of Kierkegaard, in his teachings concerning paradox, that Christianity appears so definite that it cannot be confused with any other spiritual trend whatever. But when one has to make one's choice between Pantheism and Christianity, then the question arises, Are Kierkegaard's teachings really historic Christianity, and not rather a rational adaptation? And this question must be answered in the negative, since it is possible to assimilate it without touching upon the question of the revelation of the Holy Ghost in the shape of a dove, to the Voice from the clouds, and the whole string of miracles and dogmas.
The next thought again was this: Pantheism does not place any one unconditional goal in front of man. The unbeliever passes his life interested in the many aims that man, as man, has. The Pantheist will therefore have difficulty in living a perfect ethical life. There are many cases in which, by deviating from the strictly ethic code, you do not harm anyone, you only injure your own soul. The Non-Believer will in this case only hardly, for the sake of impersonal Truth, make up his mind to the step which the God-fearing man will take actuated by his passionate fear of offending God.
Thus was I tossed backwards and forwards in my reflections.
