But he had yielded—he was no martyr! Yes, indeed! But be it remembered, that if he possessed not the moral courage of a Huss, a Savonarola, or a Luther, he was not called to exercise it in so high a cause. The assertion and support of a religious truth is impressed with far deeper obligations than the advocacy of a scientific one, however well maintained by analogy, and confirmed by reason.
Still there was a deep devotional sentiment that pervaded the character of Galileo. Before he died, he became totally blind; yet he did not despair. Like Milton, he labored on for mankind—nay, pursued his scientific studies, inventing mechanical substitutes for his loss of vision, to enable him still to pursue his arduous researches.
It is true he was shut out, like the elder Herschel, from the view of that glorious company, toward which his spirit had so often soared. Well might his friend Castelli say, in allusion to his infirmity, "that the noblest eyes were darkened which nature had ever made—eyes so privileged, and gifted with such rare qualities, that they might be said to have seen more than all those who had gone before him, and to have opened the eyes of all who were to come." Galileo himself bore noble tribute to his friend, when he exclaimed,
"Never, never will I cease to use the senses which God has left me; and though this heaven, this earth, this universe, be henceforth shrunk for me into the narrow space which I myself fill, so it please God, it shall content me."
The malice of his enemies long survived his death. The partisans of Rome disputed his right to make a will. They denied him a monument for which large sums had been subscribed.
A hundred years afterward, when a splendid memorial was about to be erected to his memory, the President of the Florentine Academy descended into his grave, and desecrated his remains, by bearing off, as relics for a museum, the thumb of his right hand, and one of his vertebræ! So the victims of the religious fury of one age become the martyrs of science in another!
And what is the moral of what we have written concerning Galileo? Is there no teaching that may instruct our own times, especially when we see how, through scorn and persecution, and this world's contumely, and through the gloom and shadows of ignorance and fear, the form and substance of mighty Truth rises, slowly and dimly, perchance, at first, but grandly and majestically ere long? Little more than two hundred years have passed since the death of Galileo, but ample justice has been done to his memory. His name will be a watchword through all time, to urge men forward in the great cause of moral and intellectual progress; and the Tree of Knowledge, whose fruits were once on earth, plucked, perhaps, ere they were matured, has shot up with its golden branches into the skies, over which has radiated the smiles of a beneficent Providence to cheer man onward in the career of virtue and intelligence.
"There is something," as a profound writer has observed,[20] "in the spirit of the present age, greater than the age itself. It is, the appearance of a new power in the world, the multitude of minds now pressing forward in the great task of the moral and intellectual regeneration of mankind."
And this cause must ultimately triumph. The energies and discoveries of men like Galileo, remote as their history becomes, have an undying influence.
The power of a great mind is like the attraction of a sun. It appears in the infinite bounds of space, far, far away, as a grain among other gold dust at the feet of the Eternal, or, at most, but as a luminous spot; and yet we know that its influence controls, and is necessary for, the order and arrangement of the nearest, as well is the remotest system. So in the moral and intellectual universe, from world to world, from star to star, the influence of one great mind extends, and we are drawn toward it by an unseen, but all-pervading affinity. Thus has the cause of moral and intellectual progress a sure guarantee of success. It has become a necessity, interwoven with the spirit of the age—a necessity impressed by every revelation of social evil, as well as proclaimed by every scientific discovery—gaining increased energy and power from the manifestation of every new wonder and mystery of nature—nay, from the building of every steam-ship, the laying down of every new line of railway.
