Guido de Ruggiero (1888-1948) was perhaps the greatest Italian intellectual historian in the twentieth century. He was a fierce champion of liberalism, an ardent opponent of Fascism, an insightful critic and interpreter of his contemporaries, and a formidable philosopher in his own right. Idealism & Experience: The Philosophy of Guido de Ruggiero comprises eight new critical essays, as well as English translations of five of de Ruggiero's most important shorter writings, which chart the development of his thought between 1914 and 1946. Taken together, these essays reveal the range, richness and philosophical sophistication of de Ruggiero's ideas, enabling Anglophone readers to appreciate their enduring relevance in our own troubled times.

The Italian author Giovanni Gentile (1875-1944) occupied a radical position among philosophers of the first half of the twentieth century. He tried in earnest to revolutionize idealist theory, developing a doctrine that retained the idealist conception of the thinking subject as the centre and source of any intelligible reality, while eschewing many of the unwarranted abstractions that had pervaded earlier varieties of idealism and led their adherents astray. Given his great prominence during his lifetime, it is perhaps remarkable that Gentile is so little discussed, and even then so poorly understood, in the English-speaking world. Few of his works have ever been translated into English, and these represent only a fraction of his great corpus and the many topics discussed therein. This neglect is partly explained by his close association with the Partito Nazionale Fascista (National Fascist Party), of which he remained a loyal member and supporter between 1923 and his assassination in 1944. The volume comprises eleven essays. Seven of these are new pieces written especially for Thought Thinking, and are intended both to contribute to ongoing debates about Gentile's philosophy and to indicate just a few of its many aspects that continue to draw the attention of philosophers, political theorists and intellectual historians. These are supplemented by new English translations of four of Gentile's shorter works, selected to offer some direct insight into his ideas and style of writing.

Recent moral philosophers have had little to say about Giovanni Gentile's 'actual idealism', which is widely dismissed as a kind of obscurantist Hegelianism used to conceal flimsy justifications for the state's total impunity over questions of morality and truth. While Gentile is increasingly recognised as a major figure in twentieth-century Italian culture, actual idealism itself has yet to be given a full and impartial philosophical appraisal. Giovanni Gentile and the State of Contemporary Constructivism represents the first book-length treatment of actual idealist moral theory. Part I describes and criticises Gentile's stated view, showing that it includes several ambiguities that he exploits in order to align it with Fascist totalitarianism. Part II develops a modified version that is more consistent with the basic tenets of actual idealism. It is argued that Gentile's theory is best understood as a radical constructivist doctrine according to which all thinking has a moral character. Rigorously conceived, it promotes not uncritical submission to the state, but free and self-regulating thought in the absence of a fully objective reality. Thus Gentile demonstrates both the plausibility and the limitations of any uncompromising form of anti-realist constructivism.
