Newton on the Beach: the Information Order of Principia Mathematica
Hist. Sci., xlvii (2009) NEWTON ON THE BEACH: THE INFORMATION ORDER OF PRINCIPIA MATHEMATICA Simon Schaffer Cambridge University WHAT I MAY SEEM TO THE WORLD I know not what I may seem to the world, but as to myself, I seem to have been only like a boy playing on the sea-shore and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.1 It is one of the most celebrated of Isaac Newton’s obiter dicta. Like many such, its provenance is hazy. The literary reference may well be to a passage from John Milton’s great redemptive poem Paradise regained (1671) where, in dialogue with Satan, Christ praises divine illumination above pagan learning: “who reads / Inces- santly, and to his reading brings not / A spirit and judgment equal or superior, / … Uncertain and unsettled still remains, / Deep verst in books, and shallow in himself, / Crude or intoxicate, collecting toys / And trifles for choice matters, worth a spunge, / As children gath’ring pebbles on the shore”.2 But the remark’s immediate relation with Newton is more ambiguous. The earliest version is found in a conversation of April 1730, three years after Newton’s death, between the gossipy man of letters Joseph Spence and the Jacobite, freemason and court tutor Andrew Ramsay. While chatting about Newton’s debt to ancient theology and his strange attitudes towards the doctrine of the Trinity, Ramsay quoted Newton’s phrase, adding it was “as great as all” of Principia mathematica.3 Never one to let a nice epigram slip, Ramsay then incorporated the expression in his 1732 Plan of education for a young prince, composed to help tutor the heirs of a noble French clan.
