The examination of a chapter of Locke’s Essay Concerning Human Understanding would induce him, at any moment, to quit every other pursuit. We read together Hume’s Essays, and some productions of Scotch metaphysicians of inferior ability—all with assiduous and friendly altercations, and the latter writers, at least, with small profit, unless some sparks of knowledge were struck out in the collision of debate. We read also certain popular French works that treat of man for the most part in a mixed method, metaphysically, morally and politically. Hume’s Essays were a favourite book with Shelley, and he was always ready to put forward in argument the doctrines they uphold.
It may seem strange that he should ever have accepted the sceptical philosophy, a system so uncongenial with a fervid and imaginative genius, which can allure the cool, cautious, abstinent reasoner alone, and would deter the enthusiastic, the fanciful and the speculative. We must bear in mind, however, that he was an eager, bold, unwearied disputant; and although the position, in which the sceptic and the materialist love to entrench themselves, offers no picturesque attractions to the eye of the poet, it is well adapted for defensive warfare, and it is not easy for an ordinary enemy to dislodge him, who occupies a post that derives strength from the weakness of the assailant. It has been insinuated that, whenever a man of real talent and generous feelings condescends to fight under these colours, he is guilty of a dissimulation, which he deems harmless, perhaps even praiseworthy, for the sake of victory in argument.
It was not a little curious to observe one, whose sanguine temper led him to believe implicitly every assertion, so that it was improbable and incredible, exulting in the success of his philosophical doubts, when, like the calmest and most suspicious of analysts, he refused to admit, without strict proof, propositions that many, who are not deficient in metaphysical prudence, account obvious and self-evident. The sceptical philosophy had another charm; it partook of the new and the wonderful, inasmuch as it called into doubt, and seemed to place in jeopardy during the joyous hours of disputation, many important practical conclusions. To a soul loving excitement and change, destruction, so that it be on a grand scale, may sometimes prove hardly less inspiring than creation. The feat of the magician, who, by the touch of his wand, could cause the Great Pyramid to dissolve into the air and to vanish from the sight, would be as surprising as the achievement of him, who, by the same rod, could instantly raise a similar mass in any chosen spot. If the destruction of the eternal monument was only apparent, the ocular sophism would be at once harmless and ingenuous: so was it with the logomachy of the young and strenuous logician, and his intellectual activity merited praise and reward.
There was another reason, moreover, why the sceptical philosophy should be welcome to Shelley at that time: he was young, and it is generally acceptable to youth. It is adopted as the abiding rule of reason throughout life, by those only who are distinguished by a sterility of soul, a barrenness of invention, a total dearth of fancy and a scanty stock of learning. Such, in truth, although the warmth of juvenile blood, the light burthen of few years and the precipitation of inexperience may sometimes seem to contradict the assertion, is the state of the mind at the commencement of manhood, when the vessel has as yet received only a small portion of the cargo of the accumulated wisdom of past ages, when the amount of mental operations that have actually been performed is small, and the materials upon which the imagination can work are insignificant; consequently, the inventions of the young are crude and frigid.
Hence the most fertile mind exactly resembles in early youth the hopeless barrenness of those who have grown old in vain as to its actual condition, and it differs only in the unseen capacity for future production. The philosopher who declares that he knows nothing, and that nothing can be known, will readily find followers among the young, for they are sensible that they possess the requisite qualifications for entering his school, and are as far advanced in the science of ignorance as their master.
A stranger who should have chanced to have been present at some of Shelley’s disputes, or who knew him only from having read some of the short argumentative essays which he composed as voluntary exercises, would have said, “Surely the soul of Hume passed by transmigration into the body of that eloquent young man; or, rather, he represents one of the enthusiastic and animated materialists of the French schools, whom revolutionary violence lately intercepted at an early age in his philosophical career.”
There were times, however, when a visitor, who had listened to glowing discourses delivered with a more intense ardour, would have hailed a young Platonist, breathing forth the ideal philosophy, and in his pursuit of the intellectual world entirely overlooking the material or noticing it only to contemn it. The tall boy, who is permitted for the first season to scare the partridges with his new fowling-piece, scorns to handle the top or the hoop of his younger brother; thus the man, whose years and studies are mature, slights the first feeble aspirations after the higher departments of knowledge, that were deemed so important during his residence at college. It seems laughable, but it is true, that our knowledge of Plato was derived solely from Dacier’s translation of a few of the dialogues, and from an English version of the French translation: we had never attempted a single sentence in the Greek. Since that time, however, I believe, few of our countrymen have read the golden works of that majestic philosopher in the original language more frequently and more carefully than ourselves; and few, if any, with more profit than Shelley. Although the source, whence flowed our earliest taste of the divine philosophy, was scanty and turbid, the draught was not the less grateful to our lips: our zeal in some measure atoned for our poverty.
Shelley was never weary of reading, or of listening to me whilst I read, passages from the dialogues contained in this collection, and especially from the Phædo; and he was vehemently excited by the striking doctrines which Socrates unfolds, especially by that which teaches that all our knowledge consists of reminiscences of what we had learned in a former existence. He often rose, paced slowly about the room, shook his long, wild locks and discoursed in a solemn tone and with a mysterious air, speculating concerning our previous condition, and the nature of our life and occupations in that world, where, according to Plato, we had attained to erudition, and had advanced ourselves in knowledge so far that the most studious and the most inventive, or, in other words, those who have the best memory, are able to call back a part only, and with much pain and extreme difficulty, of what was formerly familiar to us.
It is hazardous, however, to speak of his earliest efforts as a Platonist, lest they should be confounded with his subsequent advancement; it is not easy to describe his first introduction to the exalted wisdom of antiquity without borrowing inadvertently from the knowledge which he afterwards acquired. The cold, ungenial, foggy atmosphere of northern metaphysics was less suited to the ardent temperament of his soul than the warm, bright, vivifying climate of southern and eastern philosophy. His genius expanded under the benign influence of the latter, and he derived copious instruction from a luminous system, that is only dark through excess of brightness, and seems obscure to vulgar vision through its extreme radiance. Nevertheless, in argument—and to argue on all questions was his dominant passion—he usually adopted the scheme of the sceptics, partly, perhaps, because it was more popular and is more generally understood. The disputant, who would use Plato as his text-book in this age, would reduce his opponents to a small number indeed.
The study of that highest department of ethics, which includes all the inferior branches and is directed towards the noblest and most important ends of jurisprudence, was always next my heart; at an early age it attracted my attention.
