Opinion rules men, and opinion is nourished by beliefs, and beliefs are created and sustained by ideas. If we permit ourselves to fall out of the intellectual movement of the age, we shall lose influence over the minds that create opinion and shape the future. "One man of science," says von Hertling, "who works with success in the fields of research, whose name is written on the page of history in far-gleaming characters, and who at the same time leads the life of a true son of the Church, outweighs whole volumes of apologetics." The truths of salvation are doubtless infinitely more important than the truths of science; but this natural knowledge so attracts the attention and awakens the interest of the men of to-day, it so transforms and improves the methods and processes by which civilization is promoted, that it has created a new world-view, not only in the minds of the few profound thinkers and original investigators, but in the general public of intelligent men and women; and if our words are to awaken a response, we must be able to place ourselves at the standpoint of our hearers. The theologian, the apologist, the orator must be able to say to the children of this generation: "We see all that you see, and beyond we see yet diviner truth." Arguments and syllogisms have little power of persuasion. We win men by showing them the facts of life; and to do this we must be able to look at things from many points. This ability is precisely what the best education confers; for it renders the mind open, luminous, fair, supple, and many sided. To live in the mind, to strive ceaselessly to learn more of the infinite truth, is not easy for any one. It requires a discipline, a courage, a spirit of self-denial, which only the fewest ever acquire; and when men of this strength and excellence devote themselves to the elucidation and defense of the doctrines of religion, we must honor and trust them, or they will lose heart or turn to studies in which their labors will be appreciated. If mistrust of our ablest minds be permitted to exist, the inevitable result will be a lowering of the whole intellectual life of Catholics, and as a consequence a lowering of their moral and religious life. If we have no great masters, how shall we hope to have eager and loving disciples? If we have no men who write vital books--books of power, books which are literature and endure--how shall we expect to enter along an inner line into the higher life of the age, to quicken, purify, and exalt the hopes and thoughts of men? Is the Bible itself written with the rigid exactness of a mathematical treatise? Is it not rather a book of life, of literature, full of symbols and metaphors and poetry? What book has been so misunderstood, and misinterpreted, even by honest and enlightened minds, even by theologians themselves?
