The Life of Reason: The Phases of Human Progress. George Santayana

of human conscience alter. A new background, a new basis of application, appears for logic, and it may be useful to restate old truths in new words, the better to prove their eternal validity. Aristotle is, in his morals, Greek, concise, and elementary. As a Greek, he mixes with the ideal argument illustrations, appreciations, and conceptions which are not inseparable from its essence. In themselves, no doubt, these accessories are better than what in modern times would be substituted for them, being less sophisticated and of a nobler stamp; but to our eyes they disguise what is profound and universal in natural morality by embodying it in images which do not belong to our life. Our direst struggles and the last sanctions of our morality do not appear in them. The pagan world, because its maturity was simpler than our crudeness, seems childish to us. We do not find there our sins and holiness, our love, charity, and honour.

      The Greek too would not find in our world the things he valued most, things to which he surrendered himself, perhaps, with a more constant self-sacrifice—piety, country, friendship, and beauty; and he might add that his ideals were rational and he could attain them, while ours are extravagant and have been missed. Yet even if we acknowledged his greater good fortune, it would be impossible for us to go back and become like him. To make the attempt would show no sense of reality and little sense of humour. We must dress in our own clothes, if we do not wish to substitute a masquerade for practical existence. What we can adopt from Greek morals is only the abstract principle of their development; their foundation in all the extant forces of human nature and their effort toward establishing a perfect harmony among them. These forces themselves have perceptibly changed, at least in their relative power. Thus we are more conscious of wounds to stanch and wrongs to fight against, and less of goods to attain. The movement of conscience has veered; the centre of gravity lies in another part of the character.

      Another circumstance that invites a restatement of rational ethics is the impressive illustration of their principle which subsequent history has afforded. Mankind has been making extraordinary experiments of which Aristotle could not dream; and their result is calculated to clarify even his philosophy. For in some respects it needed experiments and clarification. He had been led into a systematic fusion of dialectic with physics, and of this fusion all pretentious modern philosophy is the aggravated extension. Socrates' pupils could not abandon his ideal principles, yet they could not bear to abstain from physics altogether; they therefore made a mock physics in moral terms, out of which theology was afterward developed. Plato, standing nearer to Socrates and being no naturalist by disposition, never carried the fatal experiment beyond the mythical stage. He accordingly remained the purer moralist, much as Aristotle's judgment may be preferred in many particulars. Their relative position may be roughly indicated by saying that Plato had no physics and that Aristotle's physics was false; so that ideal science in the one suffered from want of environment and control, while in the other it suffered from misuse in a sphere where it had no application.

      Plato's myths in lieu of physics.

      What had happened was briefly this: Plato, having studied many sorts of philosophy and being a bold and universal genius, was not satisfied to leave all physical questions pending, as his master had done. He adopted, accordingly, Heraclitus's doctrine of the immediate, which he now called the realm of phenomena; for what exists at any instant, if you arrest and name it, turns out to have been an embodiment of some logical essence, such as discourse might define; in every fact some idea makes its appearance, and such an apparition of the ideal is a phenomenon. Moreover, another philosophy had made a deep impression on Plato's mind and had helped to develop Socratic definitions: Parmenides had called the concept of pure Being the only reality; and to satisfy the strong dialectic by which this doctrine was supported and at the same time to bridge the infinite chasm between one formless substance and many appearances irrelevant to it, Plato substituted the many Socratic ideas, all of which were relevant to appearance, for the one concept of Parmenides. The ideas thus acquired what is called metaphysical subsistence; for they stood in the place of the Eleatic Absolute, and at the same time were the realities that phenomena manifested.

      The technique of this combination is much to be admired; but the feat is technical and adds nothing to the significance of what Plato has to say on any concrete subject. This barren triumph was, however, fruitful in misunderstandings. The characters and values a thing possessed were now conceived to subsist apart from it, and might even have preceded it and caused its existence; a mechanism composed of values and definitions could thus be placed behind phenomena to constitute a substantial physical world. Such a dream could not be taken seriously, until good sense was wholly lost and a bevy of magic spirits could be imagined peopling the infinite and yet carrying on the business of earth. Aristotle rejected the metaphysical subsistence of ideas, but thought they might still be essences operative in nature, if only they were identified with the life or form of particular things. The dream thus lost its frank wildness, but none of its inherent incongruity: for the sense in which characters and values make a thing what it is, is purely dialectical. They give it its status in the ideal world; but the appearance of these characters and values here and now is what needs explanation in physics, an explanation which can be furnished, of course, only by the physical concatenation and distribution of causes.

      Aristotle's final causes. Modern science can avoid such expedients.

      Aristotle himself did not fail to Aristotle's make this necessary distinction between efficient cause and formal essence; but as his science was only natural history, and mechanism had no plausibility in his eyes, the efficiency of the cause was always due, in his view, to its ideal quality; as in heredity the father's human character, not his physical structure, might seem to warrant the son's humanity. Every ideal, before it could be embodied, had to pre-exist in some other embodiment; but as when the ultimate purpose of the cosmos is considered it seems to lie beyond any given embodiment, the highest ideal must somehow exist disembodied. It must pre-exist, thought Aristotle, in order to supply, by way of magic attraction, a physical cause for perpetual movement in the world.

      It must be confessed, in justice to this consummate philosopher, who is not less masterly in the use of knowledge than unhappy in divination, that the transformation of the highest good into a physical power is merely incidental with him, and due to a want of faith (at that time excusable) in mechanism and evolution. Aristotle's deity is always a moral ideal and every detail in its definition is based on discrimination between the better and the worse. No accommodation to the ways of nature is here allowed to cloud the kingdom of heaven; this deity is not condemned to do whatever happens nor to absorb whatever exists. It is mythical only in its physical application; in moral philosophy it remains a legitimate conception.

      Truth certainly exists, if existence be not too mean an attribute for that eternal realm which is tenanted by ideals; but truth is repugnant to physical or psychical being. Moreover, truth may very well be identified with an impassible intellect, which should do nothing but possess all truth, with no point of view, no animal warmth, and no transitive process. Such an intellect and truth are expressions having a different metaphorical background and connotation, but, when thought out, an identical import. They both attempt to evoke that ideal standard which human thought proposes to itself. This function is their effective essence. It insures their eternal fixity, and this property surely endows them with a very genuine and sublime reality. What is fantastic is only the dynamic function attributed to them by Aristotle, which obliges them to inhabit some fabulous extension to the physical world. Even this physical efficacy, however, is spiritualised as much as possible, since deity is said to move the cosmos only as an object of love or an object of knowledge may move the mind. Such efficacy is imputed to a hypostasised end, but evidently resides in fact in the functioning and impulsive spirit that conceives and pursues an ideal, endowing it with whatever attraction it may seem to have. The absolute intellect described by Aristotle remains, therefore, as pertinent to the Life of Reason as Plato's idea of the good. Though less comprehensive (for it abstracts from all animal interests, from all passion and mortality), it is more adequate and distinct in the region it dominates. It expresses sublimely the goal of speculative thinking; which is none other than to live as much as may be in the eternal and to absorb and be absorbed in the truth.

      The rest of ancient philosophy belongs to the decadence and rests in physics on eclecticism and in morals on despair. That creative breath which had stirred the founders and legislators of Greece no longer inspired their
