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.
