From any unjust restriction, we said. For this is clear: if under certain circumstances there might be warrant for a just restriction by external authority, such a restriction could not be refused in the name of freedom. So long, then, as we understand by freedom a lawful freedom, there cannot be included in this the freedom from every external authority, but only from unlawful interference. There is, then, the question whether there may be a legitimate restraint, imposed by external authority, which man must not evade, and what the nature of such restraint may be.
We must, moreover, take into consideration two elements, which are distinguished in the above definitions, both belonging to the modern idea of scientific freedom. We will call them freedom of research, and freedom of teaching. The investigator and the scientist claim the one; the teacher, the other. Searching after truth, and communicating the truth found, are, as is known, the principal occupations of science. The scientist should first of all be an investigator. He should not be content to appropriate to himself the knowledge of others, he should also make his own additions to knowledge. He is also commonly a teacher, by word of mouth, as at the university, or by his writing, in his literary activity. Research, as such, imparts directly a certain knowledge only to the investigator; it is of a private nature and as such does not reach beyond him. But by teaching, his ideas are communicated to others, and then begin to influence their thought, will, and action, often very strongly. Teaching is a social factor; with it are bound up the weal and woe of others. Suppose a man of influence conceives in his study the idea that monogamy is an infringement upon the universal rights of man; should he be given without any ado the right of disseminating, by teaching, the imagined results of his investigation, to the confusion of men, and with serious danger to the peace of society?
We shall therefore have to distinguish between freedom of research and freedom of teaching. The neglect of this distinction causes not a little confusion; thus, if one complains of his convictions being trammeled or his liberty of conscience being violated, when he is hindered from immediately proclaiming whatever he calls his convictions. Private opinion, and the public propaganda of this opinion, are evidently very different things. It may be that an opinion seems to me the right one, but, in spite of that, public dissemination of it may, always or under certain circumstances, mean danger to my fellow-men. If I am for this reason prevented from publishing it, I am not thereby hindered from giving it my own private assent. It is, moreover, quite clear that the state – we disregard here religious authority – cannot at all directly restrict research, which is something personal. It can only impose restrictions on the communication of one's ideas by teaching them to others, which is a social function.
From these few remarks will be followed the impropriety of the following, or similar, observations: “The fostering of science and its teaching are not separate functions … to insinuate a twofold function of freedom, viz., that of the savant and that of the teacher, would be to dissolve the unity of the moral personality” (W. Kahl, Bekenntnissgebundenheit und Lehrfreiheit (1897), 22). It is not at all double-dealing if some one does not publicly proclaim one's private knowledge. Is it double-dealing, is it a violation of “the unity of the moral personality,”if one is, and must be, silent about official secrets? And if one does not tell, and is not allowed to tell, official secrets, if one prevents an anarchist from spreading his revolutionary ideas, is this a violation of the unity of the moral personality? It is true that “to deny one's convictions is a violation of one of the most indubitable principles of moral conduct” (K. v. Amira, Die Stellung des akademischen Lehrers zur Freiheit in Forschung und Lehre. Beilage der Muenchener Neuesten Nachrichten. 9. Juli, 1908). But it is logically incorrect to conclude therefrom that the freedom of teaching should not be restricted. To keep silence is not denying one's convictions. Later on, when speaking of freedom in teaching, we shall return to this thought and deal with it more thoroughly.
So far there can be no serious diversity of opinion. Freedom from unjust restraint is demanded, and rightly demanded, for science. The very object of science requires it. In scientific research man's power of discernment should freely develop; his inclination towards truth should exert itself; and by communication of acquired knowledge mankind should advance in mental and material culture.
The bud bursts forth and freely unfolds its splendour; the butterfly grows unhindered in beauty; the tree, too, wants freedom, in order to develop its boughs and branches according to its nature, and if you try to bind and tie it, it resists as much as it can. Just so is freedom needful for the development of the noblest aspirations of human nature, for its progress in knowledge. Every friend of humanity, every one who loves his own kind, must be in sympathy with its progress. Who will not rejoice to see the mind of man happily trace the laws of nature, laid down by the Spirit of God in the stillness of eternity when as yet there was no creature to heed, the laws He then placed in nature in order that the reasonable creature might discern the marks of his Creator? Who would not rejoice to see man, diligently following the facts of history and studying the works of literature and art, find therein the ideas of God reflected, as the rays of the sun in the trembling drop of dew, and, finally, trying to solve the difficult problems of life? To this end has the Creator enkindled in the mind of man a spark of His own intelligence; to this end has He put in him a desire to inquire and learn, a desire which has exerted itself most in the noblest of men. Man is destined to find his ultimate gratification in beholding the Eternal Truth and Beauty, a vision which will be the completion of human science and culture, the highest perfection of created life. Thus man's noble desire for knowledge and truth must develop, it must be able to produce leaves and blossoms. For this he needs freedom, free air, and free light.
If science is to attain its high purpose, it must have freedom also to impart the knowledge acquired. It should indeed further the progress of mankind. By its discovery it should enhance the beauty of human life, should enrich the treasure of human knowledge, should promote education and morality, to the honour of the Creator. For this end, too, freedom is necessary: freedom to impart newly acquired knowledge, else there would be no pleasure in work, stagnation rather than progress.
Chapter II. Two Views Of The World And Their Freedom
There can, then, be no difference of opinion on this matter among sober-minded men: science must be free from all unjust hindrances and restraint. But we have not yet finished. We have not even proceeded very far on our way. The further question at once presents itself: Which are those unjust hindrances and restraints that scientific research and teaching may reject? May there not perhaps be such which it must respect? There is little meaning in the cry: Freedom! Freedom! This attractive word, which always finds an enthusiastic echo in man, may easily prove a misleading catchword, and become a dangerous weapon of the thoughtless and the unscrupulous.
