Attempts have not been wanting, however, to find an empirical support for belief in the immortality of the soul, and among these may be counted the work of Frederic W.H. Myers on Human Personality and its Survival of Bodily Death. No one ever approached more eagerly than myself the two thick volumes of this work in which the leading spirit of the Society for Psychical Research resumed that formidable mass of data relating to presentiments, apparitions of the dead, the phenomena of dreams, telepathy, hypnotism, sensorial automatism, ecstasy, and all the rest that goes to furnish the spiritualist arsenal. I entered upon the reading of it not only without that temper of cautious suspicion which men of science maintain in investigations of this character, but even with a predisposition in its favour, as one who comes to seek the confirmation of his innermost longings; but for this reason was my disillusion all the greater. In spite of its critical apparatus it does not differ in any respect from medieval miracle-mongering. There is a fundamental defect of method, of logic.

And if the belief in the immortality of the soul has been unable to find vindication in rational empiricism, neither is it satisfied with pantheism. To say that everything is God, and that when we die we return to God, or, more accurately, continue in Him, avails our longing nothing; for if this indeed be so, then we were in God before we were born, and if when we die we return to where we were before being born, then the human soul, the individual consciousness, is perishable. And since we know very well that God, the personal and conscious God of Christian monotheism, is simply the provider, and above all the guarantor, of our immortality, pantheism is said, and rightly said, to be merely atheism disguised; and, in my opinion, undisguised. And they were right in calling Spinoza an atheist, for his is the most logical, the most rational, system of pantheism.

Neither is the longing for immortality saved, but rather dissolved and submerged, by agnosticism, or the doctrine of the unknowable, which, when it has professed to wish to leave religious feelings scathless, has always been inspired by the most refined hypocrisy. The whole of the first part of Spencer's First Principles, and especially the fifth chapter entitled "Reconciliation"—that between reason and faith or science and religion being understood—is a model at the same time of philosophical superficiality and religious insincerity, of the most refined British cant. The unknowable, if it is something more than the merely hitherto unknown, is but a purely negative concept, a concept of limitation. And upon this foundation no human feeling can be built up.

The science of religion, on the other hand, of religion considered as an individual and social psychic phenomenon irrespective of the transcendental objective validity of religious affirmations, is a science which, in explaining the origin of the belief that the soul is something that can live disjoined from the body, has destroyed the rationality of this belief. However much the religious man may repeat with Schleiermacher, "Science can teach thee nothing; it is for science to learn from thee," inwardly he thinks otherwise.

From whatever side the matter is regarded, it is always found that reason confronts our longing for personal immortality and contradicts it. And the truth is, in all strictness, that reason is the enemy of life.

A terrible thing is intelligence. It tends to death as memory tends to stability. The living, the absolutely unstable, the absolutely individual, is, strictly, unintelligible. Logic tends to reduce everything to identities and genera, to each representation having no more than one single and self-same content in whatever place, time, or relation it may occur to us. And there is nothing that remains the same for two successive moments of its existence. My idea of God is different each time that I conceive it. Identity, which is death, is the goal of the intellect. The mind seeks what is dead, for what is living escapes it; it seeks to congeal the flowing stream in blocks of ice; it seeks to arrest it. In order to analyze a body it is necessary to extenuate or destroy it. In order to understand anything it is necessary to kill it, to lay it out rigid in the mind. Science is a cemetery of dead ideas, even though life may issue from them. Worms also feed upon corpses. My own thoughts, tumultuous and agitated in the innermost recesses of my soul, once they are torn from their roots in the heart, poured out on to this paper and there fixed in unalterable shape, are already only the corpses of thoughts. How, then, shall reason open its portals to the revelation of life? It is a tragic combat—it is the very essence of tragedy—this combat of life with reason. And truth? Is truth something that is lived or that is comprehended?

It is only necessary to read the terrible Parmenides of Plato to arrive at his tragic conclusion that "the one is and is not, and both itself and others, in relation to themselves and one another, are and are not, and appear to be and appear not to be." All that is vital is irrational, and all that is rational is anti-vital, for reason is essentially sceptical.

The rational, in effect, is simply the relational; reason is limited to relating irrational elements. Mathematics is the only perfect science, inasmuch as it adds, subtracts, multiplies, and divides numbers, but not real and substantial things, inasmuch as it is the most formal of the sciences. Who can extract the cube root of an ash-tree?

Nevertheless we need logic, this terrible power, in order to communicate thoughts and perceptions and even in order to think and perceive, for we think with words, we perceive with forms. To think is to converse with oneself; and speech is social, and social are thought and logic. But may they not perhaps possess a content, an individual matter, incommunicable and untranslatable? And may not this be the source of their power?

The truth is that man, the prisoner of logic, without which he cannot think, has always sought to make logic subservient to his desires, and principally to his fundamental desire. He has always sought to hold fast to logic, and especially in the Middle Ages, in the interests of theology and jurisprudence, both of which based themselves on what was established by authority. It was not until very much later that logic propounded the problem of knowledge, the problem of its own validity, the scrutiny of the metalogical foundations.
