Genius is mainly an affair of energy.
It is not in the outward and visible world of material life that the Celtic genius of Wales or Ireland can at this day hope to count for much; it is in the inward world of thought and science.What it has been, what is has done, what it will be or will do, as a matter of modern politics.
Genius is mainly an affair of energy, and poetry is mainly an affair of genius; therefore a nation whose spirit is characterized by energy may well be imminent in poetry - and we have Shakespeare.
