The greatest part of the writings contributed by Croce to the _Critica_ during these years were later collected in volumes, of which however only the _Problemi d'Estetica_ (1910), containing, besides the Heidelberg lecture, a large number of essays both on the theory and history of Æsthetics, appeared before the end of the period we are now considering. To intensify the action of both his books and his review, he initiated in 1906, in connection with the publisher Laterza of Bari, the publication of a series of _Classici della filosofia moderna_, in which he published his own translation of Hegel's Encyclopedia; and in 1909, of the collection _Scrittori d' Italia_, which is in the way to becoming the standard corpus of Italian Literature. He took also a leading part in the editing of the same publisher's _Biblioteca di cultura moderna_, which was enriched through his care and advice with reprints of rare works of southern Italian writers of the Risorgimento and of the early years of the Unity, and with translations of books representative of foreign contemporary thought. If we add to all this, a number of scattered essays and monographs, editions of texts and documents, and bibliographies, and the generous cooperation, extending from the friendly discussion of plans and ideas to the humble reading of proofs, with a host of friends and disciples, we have a fairly complete idea of the significance of Croce in the cultural life of young Italy. He very rapidly became something like an institution; he was hailed as the master and spiritual guide of the new generation. His work and his example, the clarity of his thought and the rhythm of his steady, harmonious, powerful activity, were an element not of the limited life of the intellectual laboratory only, but of the spiritual life of the nation.

INTUITION AND EXPRESSION[1] The four grades of spiritual activity--Intuition and conceptual knowledge--The intuitive consciousness--The limits of intuitive knowledge--Identifications of intuition and expression--Art as expression: content and form--Language as expression; the reality of words--Croce's use of the word intuition--The lyrical character of the pure intuition.
