Whether this term indicates a man who loves wisdom or one who loves science, is of little moment to-day, and there was no such distinction in ancient times. We remember that it was entirely undecided among the Greeks whether a mathematician, an astronomer, a physician, an orator, or a student of the art of living deserved the title of a philosopher. These professions were not clearly distinguished. They were wrapped up one in another like the embryo in a mother's womb. While humanity had still little knowledge, a man might well be wise. But to-day it is necessary to specialize, to devote one's self to a special science, because the field of exploration has grown so extended. The philosopher of to-day is no longer a wise man, but a specialist.
The stars are the objects of astronomy, the animals of zoology, the plants of botany. Who and what are now the objects of philosophy? This may be explained in one word to an expert. But if we try to give information to the general public, the matter becomes difficult.
What do I know about the shoe industry, if I know that it produces shoes? I know something general about it, but I have no knowledge of its details. It is impossible to give sufficient information on the details of shoemaking to any one in a few words, not even to an educated person. Neither is it possible to explain the object of philosophy in such a way. The object may be stated, but not explained, for it cannot be made plain and brought home to the understanding in a few words.
That is the word, understanding. The understanding is the object of philosophy.
We must at once call the reader's attention to the ambiguity of this term. Understanding, knowledge, is the object of all science. That is nothing special. Every study seeks to enlighten the brain. But philosophy wishes to be a science and does not desire to relapse into antiquity by becoming universal wisdom. To say that understanding is the object of philosophy is to give merely the same reply which Thales, Pythagoras, or Plato would have given. Has proud philosophy gained nothing since? What is its positive achievement? That is the question.
Philosophy to-day still has understanding for its object. But it is no longer indefinite understanding which tries to embrace everything, but rather the understanding of the method by which knowledge may be gained. Philosophy now wishes to learn how it comes to pass that other objects may be illumined by the mind. To speak plainly, it is no longer the understanding which seeks to know everything as it did at the time of Socrates that is now the special study of philosophy, but rather the mind itself, its method and the perceptive powers of thought and understanding.
If this were all, if the world's wise men had done nothing but to at last find the object of philosophy, it would be a very scanty achievement. No, the harvest is much richer. The present day theory of human understanding is a real science, which well deserves to be popularized. Our ancestors sought understanding after the manner of Socrates and Plato in the entrails of the human brain, while at the same time despising the experience outside of it. They hoped to find truth by cudgeling their brain. "Honor to Socrates, honor to Plato; but still more honor to Truth!"
Aristotle showed a little more interest in the outer world. With the downfall of the old social stage the old philosophy naturally succumbed also. It did not revive until a few hundred years ago, at the beginning of modern times.
A short while ago, Shakespeare attracted much attention, when some one claimed to have discovered that it was not he who wrote those famous dramas and tragedies, but his contemporary Bacon of Verulam, Lord Chancellor of England. Whether Shakespeare keeps his laurels or not, Bacon's name is still great enough, for it is generally accepted as the mile stone of modern philosophy.
