§ [153]. But the advance of Spinoza over the Eleatics must not be lost sight of. The modern philosopher has so conceived being as to provide for parts within an individual unity. The geometrical analogy is a most illuminating one, for it enables us to understand how manyness may be indispensable to a being that is essentially unitary. The triangle as triangle is one. But it could not be such without sides and angles. The unity is equally necessary to the parts, for sides and angles of a triangle could not be such without an arrangement governed by the nature triangle. The whole of nature may be similarly conceived: as the reciprocal necessity of natura naturans, or nature defined in respect of its unity, and natura naturata, or nature specified in detail. There is some promise here of a reconciliation of the Way of Opinion with the Way of Truth. Opinion would be a gathering of detail, truth a comprehension of the intelligible unity. Both would be provided for through the consideration that whatever is complete and necessary must be made up of incompletenesses that are necessary to it.

Transition to Teleological Conceptions.

§ [154]. This consideration, however, does not receive its most effective formulation in Spinoza. The isolation of the parts, the actual severalty and irrelevance of the modes, still presents a grave problem. Is there a kind of whole to which not only parts but fragments, or parts in their very incompleteness, are indispensable? This would seem to be true of a progression or development, since that would require both perfection as its end, and degrees of imperfection as its stages. Spinoza was prevented from making much of this idea by his rejection of the principle of teleology. He regarded appreciation or valuation as a projection of personal bias. "Nature has no particular goal in view," and "final causes are mere human figments." "The perfection of things is to be reckoned only from their own nature and power."[318:7] The philosophical method which Spinoza here repudiates, the interpretation of the world in moral terms, is Platonism, an independent and profoundly important movement, belonging to the same general realistic type with Eleaticism and Spinozism. Absolute being is again the fundamental conception. Here, however, it is conceived that being is primarily not affirmation or self-sufficiency, but the good or ideal. There are few great metaphysical systems that have not been deeply influenced by Platonism; hence the importance of understanding it in its purity. To this end we must return again to the early Greek conception of the philosopher; for Platonism, like Eleaticism, is a sequel to the philosopher's self-consciousness.

Early Greek Philosophers not Self-critical.

§ [155]. Although the first Greek philosophers, such men as Thales, Heraclitus, Parmenides, and Empedocles, were clearly aware of their distinction and high calling, it by no means follows that they were good judges of themselves. Their sense of intellectual power was unsuspecting; and they praised philosophy without definitely raising the question of its meaning. They were like unskilled players who try all the stops and scales of an organ, and know that somehow they can make a music that exceeds the noises, monotones or simple melodies of those who play upon lesser instruments. They knew their power rather than their instrument or their art. The first philosophers, in short, were self-conscious but not self-critical.

Curtailment of Philosophy in the Age of the Sophists.

§ [156]. The immediately succeeding phase in the history of Greek philosophy was a curtailment, but only in the most superficial sense a criticism, of the activity of the philosopher. In the Periclean Age philosophy suffered more from inattention than from refutation. The scepticism of the sophists, who were the knowing men of this age, was not so much conviction as indisposition. They failed to recognize the old philosophical problem; it did not appeal to them as a genuine problem. The sophists were the intellectual men of an age of humanism, individualism, and secularism. These were years in which the circle of human society, the state with its institutions, citizenship with its manifold activities and interests, bounded the horizon of thought. What need to look beyond? Life was not a problem, but an abundant opportunity and a sense of capacity. The world was not a mystery, but a place of entertainment and a sphere of action. Of this the sophists were faithful witnesses. In their love of novelty, irreverence, impressionism, elegance of speech, and above all in their praise of individual efficiency, they preached and pandered to their age. Their public, though it loved to abuse them, was the greatest sophist of them all—brilliant and capricious, incomparably rich in all but wisdom. The majority belonged to what Plato called "the sight-loving, art-loving, busy class." This is an age, then, when the man of practical common-sense is preëminent, and the philosopher with his dark sayings has passed away. The pride of wisdom has given way to the pride of power and the pride of cleverness. The many men pursue the many goods of life, and there is no spirit among them all who, sitting apart in contemplation, wonders at the meaning of the whole.

Socrates and the Self-criticism of the Philosopher.

§ [157]. But in their midst there moved a strange prophet, whom they mistook for one of themselves. Socrates was not one who prayed in the wilderness, but a man of the streets and the market-place, who talked rather more incessantly than the rest, and apparently with less right. He did not testify to the truth, but pleaded ignorance in extenuation of an exasperating habit of asking questions. There was, however, a humor and a method in his innocence that arrested attention. He was a formidable adversary in discussion from his very irresponsibility; and he was especially successful with the more rhetorical sophists because he chose his own weapons, and substituted critical analysis, question and answer, for the long speeches to which these teachers were habituated by their profession. He appeared to be governed by an insatiable inquisitiveness, and a somewhat malicious desire to discredit those who spoke with authority.

But to those who knew him better, and especially to Plato, who knew him best, Socrates was at once the sweetest and most compelling spirit of his age. There was a kind of truth in the quality of his character. He was perhaps the first of all reverent men. In the presence of conceit his self-depreciation was ironical, but in another presence it was most genuine, and his deepest spring of thought and action. This other presence was his own ideal. Socrates was sincerely humble because, expecting so much of philosophy, he saw his own deficiency. Unlike the unskilled player, he did not seek to make music; but he loved music, and knew that such music as is indeed music was beyond his power. On the other hand he was well aware of his superiority to those in whom self-satisfaction was possible because they had no conception of the ideal. Of such he could say in truth that they did not know enough even to realize the extent of their ignorance. The world has long been familiar with the vivid portrayal of the Socratic consciousness which is contained in Plato's "Apology." Socrates had set out in life with the opinion that his was an age of exceptional enlightenment. But as he came to know men he found that after all no one of them really knew what he was about. Each "sight-loving, art-loving, busy" man was quite blind to the meaning of life. While he was capable of practical achievement, his judgments concerning the real virtue of his achievements were conventional and ungrounded, a mere reflection of tradition and opinion. When asked concerning the meaning of life, or the ground of his opinions, he was thrown into confusion or aggravated to meaningless reiteration. Such men, Socrates reflected, were both unwise and confirmed in their folly through being unconscious of it. Because he knew that vanity is vanity, that opinion is indeed mere opinion, Socrates felt himself to be the wisest man in a generation of dogged unwisdom.
