Obviously this thought must have crossed many minds before 1786, for even between English and Latin, say, there are enough similarities – one, two, three, unus, duo, tres – to make one think there may be some sort of a connection. But until the turn of the eighteenth century such speculations had foundered immediately on the great reefs of dissimilarity surrounding the occasional identical rocks. After all the main thing anyone knew about languages was that they were so different they had to be learnt one at a time. The great alteration Jones and his successors brought to the problem was the idea of looking not for chance resemblances – which had already been used to ‘prove’ relationships all over the map – but for regular change. Bad in modern Persian had the same sound and sense as ‘bad’ in English (remarked A. E. Pott in 1833), but that was just coincidence. On the other hand xvahar in Persian was originally the same word as xo in Ossetic, and both were related to English ‘sister’; furthermore the intermediate stages could be inferred and on occasion recovered.10 Like many mental revolutions, this linguistic one depended on being counterintuitive. It was also to an intense degree comparative, using many languages to explain and corroborate each other; and, since different stages of the same language could be used comparatively, by nature overwhelmingly historical. ‘Philology unfolds the genesis of those laws of speech which grammar contemplates as a finished result’ says a citation in the OED, dated 1852. Its author did not mean ‘philology’ in any of the senses quoted from the OED above; he meant comparative philology, the science inspired by Sir William and carried on through many inheritors to Professor Tolkien himself. One may remark that the confidence with which ‘genesis’ is approached was characteristic of the time.
By 1852, indeed, ‘the new philology’ had many triumphs to look back on, with several yet to come: one might pick out the prize-winning essay of Rasmus Rask in 1814, on Old Icelandic, and on the relationship of Scandinavian languages to Slavic, Celtic, Finnish and Classical ones; the enormous ‘Comparative Grammar’ or Vergleichende Grammatik of Franz Bopp in 1833–49, which covered Sanskrit, Zend, Armenian, Greek, Latin, Lithuanian, Old Slavic, Gothic and German; the Deutsche Grammatik (1819) of Jacob Grimm, and all their many successors.11 The point which all these works brandished was the intensely systematic nature of discovery, expressed as time went on increasingly by the word ‘laws’ (see OED citation above), and on the analogy of physics or chemistry by the association of laws with discoverers: Grimm’s Law, Verner’s Law, Kuhn’s Law, Thomsen’s Law, etc. There was and still is something insidiously fascinating about the relationships these laws uncover, in such detail and such profusion. Latin pisces is the same word as Old English fisc, observed Jacob Grimm, or indeed modern English ‘fish’; pes is the same as ‘foot’ and pellis as ‘fell’ (the old word for ‘skin’). What about porcus and ‘pig’ though, where the p/f alternation breaks down? Well, there is an Old English word fearh which corresponds properly, noted Grimm, its modern descendant being ‘farrow’, again an old or dialectal word for a ‘birth’ of piglets. The mill of comparisons will not work on basic or standard or literary languages alone, but demands ever-increasing grist from older or localised or sub-standard forms. The reward it offers is first an increasing sense that everything can be worked out, given time and material, second an exciting tension between the modern meanings of words – words everyone has known all their lives – and what appear as the ancient meanings. ‘Daughter’ in modern Hindustani comes out as beti; yet there is a connection between the two languages in the word dudh, ‘milk’. In ancient days, it seems, a word like Sanskrit duhitar meant ‘the little milker’; but the job was so often given to daughters that task and relationship became fused. It ‘opens before our eyes a little idyll of the poetical and pastoral life of the early Aryans’ enthused Max Müller,12 whose lectures on comparative philology bowled over not only (or not even) the learned world in the 1860s and after, but also London’s high society. Comparison was the rage: it didn’t tell you only about words, it told you about people.
But somewhere towards the end of the nineteenth century things had begun to go wrong. As is obvious from all that Tolkien ever said about literature and about philology, he felt that he had taken over (perhaps unfairly, but possibly not) a losing position in the academic game from his predecessors. Why – he could hardly have helped wondering – was that? Why had philology so ignominiously belied its promise?
Probably the short answer is that the essence of comparative philology was slog. There is something wistful in Tolkien’s astonished praise of the ‘dull stodges’ of Leeds University (Biography, p. 111), in his insistence that at Leeds anyway ‘Philology is making headway … and there is no trace of the press-gang!’ (Letters, p. 11). For matters were different elsewhere. No science, Jacob Grimm had said of philology, was ‘prouder, nobler, more disputatious, or less merciful to error’ (my italics). All its practitioners accepted, to a degree now incredible, a philosophy of rigid accuracy, total coverage, utter right and utter wrong: in 1919 the old and massively distinguished Eduard Sievers happily put his reputation on the line when he offered to dissect a text provided unseen by Hans Lietzmann, and to show from linguistic evidence how many authors had composed it (he had already done the same thing to the Epistles of Paul). He got Lietzmann’s specimen totally wrong. But no one said the idea of the test itself was unfair.13 Further down the scale, the discoveries of Grimm and his successors as far as Ferdinand de Saussure (now famous for inventing ‘structuralism’ but before that a student of Ablaut) were communicated increasingly to students as facts, systems of facts, systems divorced from the texts they had been found in. We must have philology within English Studies, wrote F. York Powell the Icelandicist in 1887, ‘or goodbye to accuracy’.14 The claim was false – you can be accurate about other things besides sound-shifts – but after seventy years of unbroken progress for the subject it was also damningly unambitious. Looking back many years later, R. W. Chambers (the man who turned down the Chair of Anglo-Saxon which eventually went to Tolkien in 1925) summed up success and failure by observing that in 1828 ‘the comparative philologist was like Ulysses’ but ‘Scoffers may say that my parallel is all too true – that students of comparative language, like [Dante’s] Ulysses, found only the mountain of Purgatory – Grimm’s Law, Verner’s Law, Grassmann’s Law – rising in successive terraces of horror – and then were overwhelmed …’ 15 Scoffers said exactly that; their viewpoint became dominant; comparative philology seen as ‘hypothetical sound-shiftings in the primeval German forests’16 went into a decline nearly as precipitate as its rise.
