"The proportion between the two things has been much misunderstood in the last century or two when for accidental and temporary reasons Europeans have attached too much importance to invention and too little to conservation.
Consider knots. The life of every sailor, the catch of every fisherman, and a thousand other things of varying importance, depend on knowing that a knot you have tied will not come untied until you set out to untie it, and will quickly come untied when you do.
There are forty or fifty knots; less than twenty are in regular use.
None has been invented at any known time, in any known place, by any known person. All are of immemorial antiquity.
For some thousands of years at least, therefore, a tradition of tying a quite small number of simple and reliable knots has been conserved; no new inventions have been added to it, because the purposes for which knots are needed are few and adequately provided for.
There is nothing to be gained by inventing a new knot; there is almost incredibly much to be lost by failure to conserve the tradition of knot-tying that we have."
(R.G. Collingwood, The New Leviathan, Oxford 1942, 301-302).
