Hugh MacDiarmid is the pseudonym of the poet Christopher Murray Grieve (1892–1978), founder of the National Party of Scotland. His poem ‘Two Scottish Boys’, with its four epigraphs, argues that poets need to be more like scientists. The two ‘boys’ he compares are the Celtic twilight poet William Sharp (1855–1905), who wrote under the pseudonym ‘Fiona Macleod’, and the physician and tropical medicine expert Sir Patrick Manson (1844–1922), nicknamed ‘Mosquito Manson’, who (see p. 204) first suggested to Ronald Ross that the mosquito was host to the malaria parasite. ‘Bunyan’s quag’ (line 4) is the Slough of Despond in The Pilgrim’s Progress; Sainte-Beuve (line 21) was a nineteenth-century French critic, and the French quotation is from an essay he published in 1857 about Flaubert’s novel Madame Bovary.

Two Scottish Boys

Not only was Thebes built by the music of an Orpheus, but without the music of some inspired Orpheus was no city ever built, no work that man glories in ever done.

Thomas Carlyle    

For the very essence of poetry is truth, and as soon as a word’s not true it’s not poetry, though it may wear the cast clothes of it.

George MacDonald   

Poetry never goes back on you. Learn as many pieces as you can. Go over them again and again till the words come of themselves, and then you have a joy forever which cannot be stolen or broken or lost. This is much better than diamond rings on every finger… The thing you cannot get a pigeon-hole for is the finger-point showing the way to discovery.

Sir Patrick Manson  

Science is the Differential Calculus of the mind. Art the Integral Calculus; they may be beautiful when apart, but are greatest only when combined.

Sir Ronald Ross
