When we remember Burns's obligations to his predecessors, we must never forget his immense advances on them. They had already "discovered" nature; but Burns discovered poetry - a higher and more intense way of thinking of the things that go to make up nature, a higher and more ideal key of words in which to speak of them. Ramsay and Fergusson excelled at making a popular - or shall we say vulgar? - sort of society verses, comical and prosaic, written, you would say, in taverns while a supper party waited for its laureate's word; but on the appearance of Burns, this coarse and laughing literature was touched to finer issues, and learned gravity of thought and natural pathos.
What he had gained from his predecessors was a direct, speaking style, and to walk on his own feet instead of on academical stilts. There was never a man of letters with more absolute command of his means; and we may say of him, without excess, that his style was his slave. Hence that energy of epithet, so concise and telling, that a foreigner is tempted to explain it by some special richness or aptitude in the dialect he wrote. Hence that Homeric justice and completeness of description which gives us the very physiognomy of nature, in body and detail, as nature is.
Hence, too, the unbroken literary quality of his best pieces, which keeps him from any slip into the weariful trade of word-painting, and presents everything, as everything should be presented by the art of words, in a clear, continuous medium of thought. Principal Shairp, for instance, gives us a paraphrase of one tough verse of the original; and for those who know the Greek poets only by paraphrase, this has the very quality they are accustomed to look for and admire in Greek. The contemporaries of Burns were surprised that he should visit so many celebrated mountains and waterfalls, and not seize the opportunity to make a poem. Indeed, it is not for those who have a true command of the art of words, but for peddling, professional amateurs, that these pointed occasions are most useful and inspiring. As those who speak French imperfectly are glad to dwell on any topic they may have talked upon or heard others talk upon before, because they know appropriate words for it in French, so the dabbler in verse rejoices to behold a waterfall, because he has learned the sentiment and knows appropriate words for it in poetry. But the dialect of Burns was fitted to deal with any subject; and whether it was a stormy night, a shepherd's collie, a sheep struggling in the snow, the conduct of cowardly soldiers in the field, the gait and cogitations of a drunken man, or only a village cockcrow in the morning, he could find language to give it freshness, body, and relief.
He was always ready to borrow the hint of a design, as though he had a difficulty in commencing - a difficulty, let us say, in choosing a subject out of a world which seemed all equally living and significant to him; but once he had the subject chosen, he could cope with nature single-handed, and make every stroke a triumph. Again, his absolute mastery in his art enabled him to express each and all of his different humours, and to pass smoothly and congruously from one to another. Many men invent a dialect for only one side of their nature - perhaps their pathos or their humour, or the delicacy of their senses - and, for lack of a medium, leave all the others unexpressed. You meet such an one, and find him in conversation full of thought, feeling, and experience, which he has lacked the art to employ in his writings. But Burns was not thus hampered in the practice of the literary art; he could throw the whole weight of his nature into his work, and impregnate it from end to end. If Doctor Johnson, that stilted and accomplished stylist, had lacked the sacred Boswell, what should we have known of him? and how should we have delighted in his acquaintance as we do? Those who spoke with Burns tell us how much we have lost who did not. But I think they exaggerate their privilege: I think we have the whole Burns in our possession set forth in his consummate verses.
