In Gaelic literature we have something that the English-speaking countries have never possessed – a great folk literature. We have in Berkeley and in Burke a philosophy on which it is possible to base the whole life of a nation. That, too, is something which England, great as she is in modern scientific thought and every kind of literature, has not, I think. The modern Irish intellect was born more than two hundred years ago when Berkeley defined in three or four sentences the mechanical philosophy of Newton, Locke, and Hobbes, the philosophy of England in his day, and I think of English up to our day, and wrote after each, “We Irish do not hold with this”, or some like sentence. Feed the immature imagination upon that old folk life, and the mature intellect upon Berkeley and the great modern idealist philosophy created by his influence, upon Burke who restored to political thought its sense of history, and Ireland is reborn, potent, armed and wise. Berkeley proved that the world was a vision, and Burke that the State was a tree, no mechanism to be pulled in pieces and put up again, but an oak tree that had grown through centuries.

A forerunner to his celebration of the 18th century philosophers in his poetry. This outlines the intellectual tradition he wished to resuscitate, which would feed the Irish intellect as the old Gaelic tales would feed the Irish imagination.
