(33) Of Skepticism as propounded by Pyrrho of Elis (365-275 B.C.) and by Timon, Sextus Empiricus said that those who seek must find or deny they have found or can find, or persevere in the inquiry. Those who suppose they have found truth are called Dogmatists; those who think it incomprehensible are the Academics; those who still seek are the Skeptics. The attitude of Skepticism towards the knowable is summed up by Sextus Empiricus in the following words: "But the chief ground of Skepticism is that to every reason there is an opposite reason equivalent, which makes us forbear to dogmatize." The Skeptics were strongly opposed to the Dogmatists and were agnostic in that they held the accepted theories regarding Deity to be self-contradictory and undemonstrable. "How," asked the Skeptic, "can we have indubitate knowledge of God, knowing not His substance, form or place; for, while philosophers disagree irreconcilably on these points, their conclusions cannot be considered as undoubtedly true?" Since absolute knowledge was considered unattainable, the Skeptics declared the end of their discipline to be: "In opinionatives, indisturbance; in impulsives, moderation; and in disquietives, suspension."

(15) Socrates (469-399 B.C.), the founder of the Socratic sect, being fundamentally a Skeptic, did not force his opinions upon others, but through the medium of questionings caused each man to give expression to his own philosophy. According to Plutarch, Socrates conceived every place as appropriate for reaching in that the whole world was a school of virtue. He held that the soul existed before the body and, prior to immersion therein, was endowed with all knowledge; that when the soul entered into the material form it became stupefied, but that by discourses upon sensible objects it was caused to reawaken and to recover its original knowledge. On these premises was based his attempt to stimulate the soul-power through irony and inductive reasoning. It has been said of Socrates that the sole subject of his philosophy was man. He himself declared philosophy to be the way of true happiness and its purpose twofold: (1) to contemplate God, and (2) to abstract the soul from corporeal sense.

(16) The principles of all things he conceived to be three in number: God, matter, and ideas. Of God he said: "What He is I know not; what He is not I know." Matter he defined as the subject of generation and corruption; idea, as an incorruptible substance--the intellect of God. Wisdom he considered the sum of the virtues. Among the prominent members of the Socratic sect were Xenophon, Æschines, Crito, Simon, Glauco, Simmias, and Cebes. Professor Zeller, the great authority on ancient philosophies, has recently declared the writings of Xenophon relating to Socrates to be forgeries. When The Clouds of Aristophanes, a comedy written to ridicule the theories of Socrates, was first presented, the great Skeptic himself attended the play. During the performance, which caricatured him seated in a basket high in the air studying the sun, Socrates rose calmly in his seat, the better to enable the Athenian spectators to compare his own unprepossessing features with the grotesque mask worn by the actor impersonating him.

(5) But whence does this science derive its own initial laws?

The Intellectual-Principle furnishes standards, the most certain for any soul that is able to apply them. What else is necessary, Dialectic puts together for itself, combining and dividing, until it has reached perfect Intellection. "For," we read, "it is the purest of Intellection and Contemplative-Wisdom." And, being the noblest method and science that exists it must needs deal with Authentic-Existence, The Highest there is: as Contemplative-Wisdom it deals with Being, as Intellection with what transcends Being.

What, then, is Philosophy?

Philosophy is the supremely precious.

Is Dialectic, then, the same as Philosophy?

It is the precious part of Philosophy. We must not think of it as the mere tool of the metaphysician: Dialectic does not consist of bare theories and rules: it deals with verities; Existences are, as it were, Matter to it, or at least it proceeds methodically towards Existences, and possesses itself, at the one step, of the notions and of the realities.

Untruth and sophism it knows, not directly, not of its own nature, but merely as something produced outside itself, something which it recognises to be foreign to the verities laid up in itself; in the falsity presented to it, it perceives a clash with its own canon of truth. Dialectic, that is to say, has no knowledge of propositions- collections of words- but it knows the truth, and, in that knowledge, knows what the schools call their propositions: it knows above all, the operation of the soul, and, by virtue of this knowing, it knows, too, what is affirmed and what is denied, whether the denial is of what was asserted or of something else, and whether propositions agree or differ; all that is submitted to it, it attacks with the directness of sense-perception and it leaves petty precisions of process to what other science may care for such exercises.

(7) In this age the word philosophy has little meaning unless accompanied by some other qualifying term. The body of philosophy has been broken up into numerous isms more or less antagonistic, which have become so concerned with the effort to disprove each other's fallacies that the sublimer issues of divine order and human destiny have suffered deplorable neglect. The ideal function of philosophy is to serve as the stabilizing influence in human thought. By virtue of its intrinsic nature it should prevent man from ever establishing unreasonable codes of life. Philosophers themselves, however, have frustrated the ends of philosophy by exceeding in their woolgathering those untrained minds whom they are supposed to lead in the straight and narrow path of rational thinking. To list and classify any but the more important of the now recognized schools of philosophy is beyond the space limitations of this volume. The vast area of speculation covered by philosophy will be appreciated best after a brief consideration of a few of the outstanding systems of philosophic discipline which have swayed the world of thought during the last twenty-six centuries. The Greek school of philosophy had its inception with the seven immortalized thinkers upon whom was first conferred the appellation of Sophos, "the wise." According to Diogenes Laertius, these were Thales, Solon, Chilon, Pittacus, Bias, Cleobulus, and Periander. Water was conceived by Thales to be the primal principle or element, upon which the earth floated like a ship, and earthquakes were the result of disturbances in this universal sea. Since Thales was an Ionian, the school perpetuating his tenets became known as the Ionic. He died in 546 B.C., and was succeeded by Anaximander, who in turn was followed by Anaximenes, Anaxagoras, and Archelaus, with whom the Ionic school ended. Anaximander, differing from his master Thales, declared measureless and indefinable infinity to be the principle from which all things were generated. Anaximenes asserted air to be the first element of the universe; that souls and even the Deity itself were composed of it.

(17) The Elean sect was founded by Phædo of Elis, a youth of noble family, who was bought from slavery at the instigation of Socrates and who became his devoted disciple. Plato so highly admired Phædo's mentality that he named one of the most famous of his discourses The Phædo. Phædo was succeeded in his school by Plisthenes, who in turn was followed by Menedemus. Of the doctrines of the Elean sect little is known. Menedemus is presumed to have been inclined toward the teachings of Stilpo and the Megarian sect. When Menedemus' opinions were demanded, he answered that he was free, thus intimating that most men were enslaved to their opinions. Menedemus was apparently of a somewhat belligerent temperament and often returned from his lectures in a badly bruised condition. The most famous of his propositions is stated thus: That which is not the same is different from that with which it is not the same. This point being admitted, Menedemus continued: To benefit is not the same as good, therefore good does not benefit. After the time of Menedemus the Elean sect became known as the Eretrian. Its exponents denounced all negative propositions and all complex and abstruse theories, declaring that only affirmative and simple doctrines could be true.

(1) We shall, therefore, deliver to you the peculiar dogmas of the Assyrians; and also clearly develop to you our own opinions; collecting some things from the infinite writings of the ancients, but others from those particulars which were comprehended by the ancients in one treatise, and pertain to the whole knowledge of divine natures. If also you should propose any philosophic inquiry, we shall discuss it for you, according to the ancient pillars of Hermes, which Plato and Pythagoras knew before, and from thence constituted their philosophy. But such things as exhibit foreign inquiries, or which are contradictory and contentious, we shall assist mildly and aptly, or we shall demonstrate their absurdity. Such, likewise, as proceed conformably to common conceptions, we shall endeavour to discuss in a way perfectly known and clear. And things, indeed, which require the experience of divine operations to an accurate knowledge of them, we shall explain, as far as this is possible to be effected by words alone; but such as are full of intellectual theory, we shall develop with a view to the purification of the soul.

(6) Philosophy has other provinces, but Dialectic is its precious part: in its study of the laws of the universe, Philosophy draws on Dialectic much as other studies and crafts use Arithmetic, though, of course, the alliance between Philosophy and Dialectic is closer.

And in Morals, too, Philosophy uses Dialectic: by Dialectic it comes to contemplation, though it originates of itself the moral state or rather the discipline from which the moral state develops.

Our reasoning faculties employ the data of Dialectic almost as their proper possession for they are mainly concerned about Matter .

And while the other virtues bring the reason to bear upon particular experiences and acts, the virtue of Wisdom is a certain super-reasoning much closer to the Universal; for it deals with correspondence and sequence, the choice of time for action and inaction, the adoption of this course, the rejection of that other: Wisdom and Dialectic have the task of presenting all things as Universals and stripped of matter for treatment by the Understanding.

But can these inferior kinds of virtue exist without Dialectic and philosophy?

Yes- but imperfectly, inadequately.

And is it possible to be a Sage, Master in Dialectic, without these lower virtues?

It would not happen: the lower will spring either before or together with the higher. And it is likely that everyone normally possesses the natural virtues from which, when Wisdom steps in, the perfected virtue develops. After the natural virtues, then, Wisdom and, so the perfecting of the moral nature. Once the natural virtues exist, both orders, the natural and the higher, ripen side by side to their final excellence: or as the one advances it carries forward the other towards perfection.

But, ever, the natural virtue is imperfect in vision and in strength- and to both orders of virtue the essential matter is from what principles we derive them.

(50) Having broken away from the scholastic and theological schools, Post-Reformation, or modern, philosophy experienced a most prolific growth along many diverse lines. According to Humanism, man is the measure of all things; Rationalism makes the reasoning faculties the basis of all knowledge; Political Philosophy holds that man must comprehend his natural, social, and national privileges; Empiricism declares that alone to be true which is demonstrable by experiment or experience; Moralism emphasizes the necessity of right conduct as a fundamental philosophic tenet; Idealism asserts the realities of the universe to be superphysical--either mental or psychical; Realism, the reverse; and Phenomenalism restricts knowledge to facts or events which can be scientifically described or explained. The most recent developments in the field of philosophic thought are Behaviorism and Neo-Realism. The former estimates the intrinsic characteristics through an analysis of behavior; the latter may be summed up as the total extinction of idealism.

(2) In the first place, therefore, we shall divide the genera of the proposed problems, in order that we may know the quantity and quality of them. And, in the next place, we shall show from what theologies the doubts are assumed, and according to what sciences they are investigated. For some things that are badly confused, require a certain distinction; others are conversant with the cause through which they subsist, and are apprehended; others, which we propose according to a certain contrariety, draw our decision on both sides; and some things require from us the whole development of mystic doctrines. Such, therefore, being the nature of the subjects of discussion, they are assumed from many places, and from different sciences. For some things introduce animadversions from what the wise men of the Chaldeans have delivered; others produce objections from what the prophets of the Egyptians teach; and there are some that, adhering to the theory of philosophers, make inquiries conformably to them. There are now likewise some, that from other opinions, which do not deserve to be mentioned, elicite a certain dubitation; and others originate from the common conceptions of mankind. These things, therefore, are of themselves variously disposed, and are multiformly connected with each other. Hence, through all these causes, a certain discussion is requisite for the management of them in a becoming manner.

(2) "Philosophy," writes Sir William Hamilton, "has been defined [as]: The science of things divine and human, and of the causes in which they are contained [Cicero]; The science of effects by their causes [Hobbes]; The science of sufficient reasons [Leibnitz]; The science of things possible, inasmuch as they are possible [Wolf]; The science of things evidently deduced from first principles [Descartes]; The science of truths, sensible and abstract [de Condillac]; The application of reason to its legitimate objects [Tennemann]; The science of the relations of all knowledge to the necessary ends of human reason [Kant];The science of the original form of the ego or mental self [Krug]; The science of sciences [Fichte]; The science of the absolute [von Schelling]; The science of the absolute indifference of the ideal and real [von Schelling]--or, The identity of identity and non-identity [Hegel]." (See Lectures on Metaphysics and Logic.)

(4) But this science, this Dialectic essential to all the three classes alike, what, in sum, is it?

It is the Method, or Discipline, that brings with it the power of pronouncing with final truth upon the nature and relation of things- what each is, how it differs from others, what common quality all have, to what Kind each belongs and in what rank each stands in its Kind and whether its Being is Real-Being, and how many Beings there are, and how many non-Beings to be distinguished from Beings.

Dialectic treats also of the Good and the not-Good, and of the particulars that fall under each, and of what is the Eternal and what the not Eternal- and of these, it must be understood, not by seeming-knowledge but with authentic science.

All this accomplished, it gives up its touring of the realm of sense and settles down in the Intellectual Kosmos and there plies its own peculiar Act: it has abandoned all the realm of deceit and falsity, and pastures the Soul in the "Meadows of Truth": it employs the Platonic division to the discernment of the Ideal-Forms, of the Authentic-Existence and of the First-Kinds : it establishes, in the light of Intellection, the unity there is in all that issues from these Firsts, until it has traversed the entire Intellectual Realm: then, resolving the unity into the particulars once more, it returns to the point from which it starts.

Now rests: instructed and satisfied as to the Being in that sphere, it is no longer busy about many things: it has arrived at Unity and it contemplates: it leaves to another science all that coil of premisses and conclusions called the art of reasoning, much as it leaves the art of writing: some of the matter of logic, no doubt, it considers necessary- to clear the ground- but it makes itself the judge, here as in everything else; where it sees use, it uses; anything it finds superfluous, it leaves to whatever department of learning or practice may turn that matter to account.

(2) “It is reported that you philosophize to every one you may happen to meet, and publicly, which Pythagoras did not think fit to do. And these things, indeed, O Hipparchus, you learnt with diligent assiduity, but you have not preserved them; having tasted, O excellent man, of Sicilian delicacies, which you ought not to have tasted a second time. If, therefore, you abandon these, I shall rejoice; but if not, you will be dead in my opinion. For it will be pious to call to mind the divine and human precepts of Pythagoras, and not to make the goods of wisdom common to those, who have not even in a dream their soul purified. For it is not lawful to extend to every casual person, things which were obtained with such great labors, and such diligent assiduity, nor to divulge the mysteries of the Eleusinian Goddesses to the profane.

For those who do either of these, are equally unjust and impious. But it will be well to consider what a great length of time we consumed in wiping away the stains which had insinuated themselves into our breasts, till, after the lapse of some years, we became fit recipients of the doctrines of Pythagoras. For as dyers previously purify garments, and then fix in the colors with which they wish them to be imbued, in order that the dye may not be washed away, and may never become evanescent; after the same manner also that divine man prepared the souls of those that were lovers of philosophy, so that they might not deceive him in any of those beautiful and good qualities which he hoped they would possess.

For he did not impart spurious doctrines, nor snares, in which most of the sophists, who are at leisure for no good purpose, entangle young men; but he possessed a scientific knowledge of things human and divine. These men, however, making his doctrine a pretext, perform many dreadful deeds, ensnaring youth not in a becoming nor yet in a casual way. Hence they render their auditors noxious and precipitate. For they infuse theorems and divine doctrines into confused and turbid manners. Just as if some one should pour pure and clear water into a deep well full of mud; for he would disturb the mud, and destroy the clear water. The same thing likewise takes place between those who teach and those who are taught after this manner.

For dense thickets and which are full of briars surround the intellect and heart of those who have not been purely initiated in disciplines, obscure the mild, tranquil, and reasoning power of the soul, and openly impede the intellective part from becoming increased and elevated. It is requisite likewise to call intemperance and avarice the mothers of these thickets; both which are naturally prolific. From intemperance, therefore, unlawful marriages, [unjust] desires, corruptions, intoxication, preternatural pleasures, and certain vehement appetites blossom forth, and which impel their possessors into profundities and precipices. For now desires have compelled some not to abstain either from their mothers or their daughters, and violating law, their country, city, and king, with their hands as it were bound behind them, they are violently dragged along like slaves to extreme destruction.

But from avarice germinate rapine, robbery, parricide, sacrilege, sorcery, and such other evils at are the sisters of these. In the first place, therefore, it is necessary to purify the woods in which these passions have fixed their abode, with fire and sword, and all the machines of disciplines; and having liberated the reasoning power from such mighty evils, we may then implant in and deliver to it something useful and good.” So great and so necessary was the attention which, according to Pythagoras, ought to be paid to disciplines prior to philosophy. He likewise ordained that a singular honor, and the most accurate investigation, should be given to the teaching and participation of his dogmas, as he judiciously examined the conceptions of those that came to him, by various documents, and ten thousand forms of scientific theory.
