Fixing a 2,500-Yr-Previous Puzzle: How a Cambridge Pupil Cracked an Historical Sanskrit Code

Should you discover your­self grap­pling with an intel­lec­tu­al prob­lem that’s gone unsolved for mil­len­nia, strive tak­ing a number of months off and spend­ing them on activ­i­ties like swim­ming and med­i­tat­ing. That very strat­e­gy labored for a Cam­bridge PhD stu­dent named Rishi Rajpopat, who, after a sum­mer of non-research-relat­ed activ­i­ties, returned to a textual content by the traditional gram­mar­i­an, logi­cian, and “father of lin­guis­tics” Pāṇi­ni and located it new­ly com­pre­hen­si­ble. The foundations of its com­po­si­tion had stumped schol­ars for two,500 years, however, as Rajpopat tells it in an arti­cle by Tom Almeroth-Williams at Cam­bridge’s net­website, “With­in min­utes, as I turned the pages, these pat­terns begin­ed emerg­ing, and all of it begin­ed to make sense.”

Pāṇi­ni com­posed his texts utilizing a form of algo­rithm: “Feed within the base and suf­repair of a phrase and it ought to flip them into gram­mat­i­cal­ly cor­rect phrases and sen­tences by a step-by-step course of,” writes Almeroth-Williams. However “usually, two or extra of Pāṇini’s guidelines are simul­ta­ne­ous­ly applic­a­ble on the similar step, leav­ing schol­ars to in the past­nize over which one to decide on.” Or such was the case, at the very least, earlier than Rajpopat’s dis­cov­ery that the dif­fi­cult-to-inter­pret “metarule” meant to use to such cas­es dic­tates that “between guidelines applic­a­ble to the left and proper sides of a phrase respec­tive­ly, Pāṇi­ni need­ed us to decide on the rule applic­a­ble to the appropriate facet.”

That is probably not imme­di­ate­ly beneath­stand­in a position to these unfa­mil­iar with the struc­ture of San­skrit. Almeroth-Williams’ piece clar­i­fies with an examination­ple utilizing  mantra, one phrase from the lan­guage that each­physique is aware of. “Within the sen­tence ‘devāḥ prasan­nāḥ mantraiḥ’ (‘The Gods [devāḥ] are happy [prasan­nāḥ] by the mantras [mantraiḥ]’) we encounter ‘rule con­flict’ when deriv­ing mantraiḥ, ‘by the mantras,’ ” he writes. ” The deriva­tion begins with ‘mantra + bhis.’ One rule is applic­a­ble to the left half ‘mantra’ and the oth­er to proper half ‘bhis.’ We should choose the rule applic­a­ble to the appropriate half ‘bhis,’ which supplies us the cor­rect kind ‘mantraih.’ ”

Apply­ing this rule ren­ders inter­pre­ta­tions of Pāṇini’s work nearly com­plete­ly unam­bigu­ous and gram­mat­i­cal. It might even be employed, Rajpopat has not­ed, to show San­skrit gram­mar to com­put­ers being professional­grammed for nat­ur­al lan­guage professional­cess­ing. It little question took him an excessive amount of inten­sive examine to succeed in the purpose the place he was in a position to dis­cov­er the true imply­ing of Pāṇini’s clar­i­fy­ing metarule, but it surely did­n’t tru­ly current itself till he let his uncon­scious thoughts take a crack at it. As we’ve mentioned right here on Open Cul­ture earlier than, there are good rea­sons we do our greatest assume­ing whereas doing issues like stroll­ing or tak­ing a present­er, a phe­nom­e­non that philoso­phers have broad­ly rec­og­nized by the ages — and, like as not, was beneath­stood by the nice Pāṇi­ni him­self.
