The first will show the effect upon the Irish mind of its obsession by politics.

The next will deal with the influence of religious systems upon the secular life of the people.

I shall then show how education, which should not only have been the most potent of all the three influences in bringing our national life into line with the progress of the age, but should also have modified the operation of the other two causes, has aggravated rather than cured the malady.
Whatever impression I may succeed in making upon others, I may here state that, as the result of observation and reflection, the conclusion has been forced upon me that the Irish mind is suffering from considerable functional derangement, but not, so far as I can discern, from any organic disease.

This is the basis of my optimism.

I shall submit in another chapter, which will conclude the first, the critical part of my book, certain new principles of treatment which are indicated by the diagnosis; and I would ask the reader, before he rejects the opinions which are there expressed, to persevere through the narrative contained in the second part of the book.
