There are two kinds of freedom, lawful and unlawful: the latter is freedom from just laws, the former from unjust laws.
We ask again, what is that lawful freedom which man may claim for his scientific activity? In other words, what are the restraints which he may reject as unjust, and as enslaving the mind? – Here the ways part. Here, too, our question goes deeper, and touches something which moves men's minds very powerfully. Two different views of the world, two opposite conceptions of man and his thought, come here in collision.
The Christian View of the World and its Freedom
On the one hand there is the Christian view of the world: it is essentially also the one which appears self-evident to every unbiassed mind. In this view man is a creature, limited in every way, therefore in many ways dependent upon external rules, forces, and authorities. To God alone is it reserved to be infinite, and, therefore, to possess in Himself all perfection, goodness, and truth; for which reason there is nothing above Him on which He could be dependent. This is not the case with man. As a creature man is subject to his Creator. The latter is master over man's life and therefore at the same time its ultimate aim. For this reason religion is of obligation to man, that is, he must honour God as He demands it; if God requires faith in a revelation, if He established a Church and duly authorized it to guide us, we must submit to it. In the same way the intellect of man is bound by the laws of objective truth, which is not of his making, but presents itself to him as a norm: he must always be subject to it whether he wishes or not. Man is, finally, a factor in social life; he lives in the family, state, and Church, in the great society of mankind; upon them he is dependent for his education and development. And society requires that man be subject to a ruling authority, that in many things his own interests be subordinated to the welfare of the community.
This is the order that God has established and wishes observed. Hence all human authority is a participation in God's supreme government. Thus it comes about that limits may be set to the scientist's free expression of his views, if the interest of the community require it.
Man is, nevertheless, free. But his freedom does not mean complete independence; nor freedom from all restraint, but only from those external restraints which are opposed to his nature and position, which hinder his legitimate development and activity. He possesses freedom, but only such a freedom as is his due, by which he can unfold and develop his physical and mental powers. To keep his place of subordination to, and dependence on, these higher authorities and powers of truth and order, tends not to injure but to improve his being, not to dwarf but to develop his personality; for they are sources of life to him, they impart to his existence order and harmony, they raise him above himself and his own littleness, they free him from the prison of his own narrowness and selfishness, from the chains of his unruly desires. If a man emancipates himself from these bonds, which he ought to bear, he has freedom of course, but an unnatural freedom, which will be harmful and perhaps ruinous to him.
Take the tree, for instance. It should have freedom for its natural growth. If you force it to creep along the ground instead of growing upward, if you deny it air and light, you infringe on the freedom it should have. Still it cannot have absolute freedom, for it is dependent on the ground from which it derives its nourishment, dependent on the laws of light and atmosphere and gravitation, on the laws of season; it must adapt itself to climate and soil. It may not say to the light: Away with you! – a stunted growth and deformity would be the result of such emancipation. It may not say to the ground: Away with you! – a sad but quick death would be its fate. It has its freedom, and in this freedom it grows and thrives. If it desires greater freedom, it would be an unnatural one, and it would tend, not to its development, but to its destruction.
Such is the Christian view of man and his thought. Here, then, there is but one question to solve: Are the external restraints imposed on me in my investigation and teaching against my nature; against the right of my mind to truth; against my position in human society? If so, then I reject them, because they mean serfdom, not duty; unjust bonds, not natural restraint. But if not, then I do not refuse them my submission. Freedom I want, but only the freedom of man.
Here we pause. Suffice it at present to have formulated the question; we shall return to this topic later and discuss it at greater length.
The Modern Idea of Freedom
The Christian view of man and his freedom, which to past ages appeared self-evident, has grown obscure to many minds, and given place to another, a more modern view.1
For the modern man, freedom, especially freedom of intellectual life, means independence from external ties, from all authority, or, to express it positively, absolute right of self-determination, autonomy. He does not recognize any law or rule which he has not imposed upon himself. In civil life, of course, it is a principle that man must submit to external, legal restraint in many things that do not directly concern his own person, but only so far as is necessary in order that others, too, may enjoy the same freedom; but also here every citizen must be able to share in the legislation, according to the rules of constitutional or republican government. But he must be free from every external restraint in whatever touches the core of his personality, his feeling, desire, thought, and the expression of his thought.
It should now be clear, from what has been said, what is meant by freedom of science. It means independence from every external authority and restraint in research and teaching, the unhindered development and assertion of one's own intellectual personality. Man must let himself be directed only by his own judgment and his instinct for the truth, or his personal need, without heeding dogmas, Church laws, tradition, or any other external norm whatsoever. This is particularly true in the domain of philosophy and religion, in questions regarding the world and life, and in fundamental social questions. This is principally, and almost exclusively, the field in which an authoritative influence of the Church, or state, or society in general, is to be feared. Hence the importance of the question of the freedom of science in this field.
This is also the manner in which the advocates of modern freedom of science unanimously describe it.
For the academic teacher, says G. Kaufmann, there are “strictly speaking only the barriers drawn by his own instinct for the truth. It is in this sense that we demand freedom of science to-day for the university teacher. The freedom of the scientist and of the academic teacher must not be limited by patented truth, nor by faint-hearted consideration” (Die Lehrfreiheit an den deutschen Universitaeten im neunzehnten Jahrhundert (1898), 36). The first resolution proposed at the Second Conference of German University Teachers, at Jena, in September, 1908, was this: “The purpose of scientific research, and the communication of its results, demand that it be independent of every consideration foreign to scientific method itself.” Of this resolution we have from another source the following explanation: “Therefore, it should be independent especially of tradition and the prejudices of the masses, independent of authority and social bodies, independent of party interest.” (This was the addition to the thesis as originally formulated by Prof. von Amira. Beilage der Muenchener Neuesten Nachrichten, July 9, 1908.) And Prof. F. Paulsen writes: “No thought can be commanded or forbidden the academic teacher or his audience” (Die deutschen Universitaeten und das Universitaets-studium, 1902, 288).
A. Harnack likewise teaches that “In regard to research and knowledge there must be unlimited freedom,”
