MacDiarmid's study of the eccentric, impulsive Scottish genius is one of his most important prose works, and takes its place as Volume IV of the MacDiarmid 2000 edition launched in 1992 to celebrate the centenary of his birth.
Christopher Murray Grieve, known by his pen name, Hugh MacDiarmid, was a Scottish poet and cultural activist.
MacDiarmid was instrumental in creating a Scottish version of modernism and was a leading light in the Scottish Renaissance of the 20th century. Unusually for a first generation modernist, he was a communist; unusually for a communist, he was a committed Scottish nationalist. He wrote in English and literary Scots (sometimes referred to as Lallans).
MacDiarmid uses Eccentric in the sense of having peculiarities and in lesser way in the modern sense. The afterwords deal with the Caledonian Antisyzygy.
