"This new fraud is just like the old ones: its essence lies in substituting something external for the use of our own reason and conscience and that of our predecessors: in the Church teaching this external thing was revelation, in the scientific teaching it is observation. The trick played by this science is to destroy man's faith in reason and conscience by directing attention to the grossest deviations from the use of human reason and conscience, and having clothed the deception in a scientific theory, to assure them that by acquiring knowledge of external phenomena they will get to know indubitable facts which will reveal to them the law of man's life. And the mental demoralization consists in this, that coming to believe that things which should be decided by conscience and reason are decided by observation, these people lose their consciousness of good and evil and become incapable of understanding the expression and definitions of good and evil that have been formed by the whole preceding life of humanity. All this, in their jargon, is conditional and subjective. It must all be abandoned - they say - the truth cannot be understood by one's reason, for one may err, but there is another path which is infallible and almost mechanical: one must study facts. And facts must be studied on the basis of the scientists' science, that is, on the basis of two unfounded propositions: positivism and evolution which are put forward as indubitable truths. And the reigning science, with not less misleading solemnity than the Church, announces that the solution of all questions of life is only possible by the study of the facts of nature, and especially of organisms. A frivolous crowd of youths mastered by the novelty of this authority, which is as yet not merely not destroyed but not even touched by criticism, throws itself into the study of these facts of natural science as the sole path which, according to the assertions of the prevailing doctrine, can lead to the elucidation of the questions of life. But the further these disciples advance in this study the further and further are they removed not only from the possibility but even from the very thought of solving life's problems, and the more they become accustomed not so much to observe as to take on trust what they are told of the observations of others (to believe in cells, in protoplasm, in the fourth state of matter,1 &c.), the more and more does the form hide the contents from them; the more and more do they lose consciousness of good and evil and capacity to understand the expressions and definitions of good and evil worked out by the whole preceding life of humanity; the more and more do they adopt the specialized scientific jargon of conventional expressions which have no general human significance; the farther and farther do they wander among the debris of quite unilluminated observations; the more and more do they lose capacity not only to think independently but even to under-stand another man's fresh human thought lying outside their Talmud; and, what is most important, they pass their best years in growing unaccustomed to life, that is, to labour, and grow accustomed to consider their condition justified, while they become physically good-for-nothing parasites. And just like the theologians and the Talmudists they completely castrate their brains and become eunuchs of thought. And just like them, to the degree to which they become stupefied, they acquire a self-confidence which deprives them for ever of the possibility of returning to a simple clear and human way of thinking."
