Doctrinal, philosophical, and religious prose
The question of how much of doctrinal writing, dealing with faith, ethics, and philosophy, can be called literature can only be answered subjectively by each reader, judging each case on its own merits. There have been philosophers who felt in no way flattered to be included among what they considered unthinking men of letters. The prejudice lingers in some quarters that profundity and clarity are mutually exclusive and that philosophy and social sciences therefore are beyond the reach of the layman. On the other hand, many writers, while often profound and fastidiously rigorous in their thought, such as Paul Valéry, have vehemently objected to being called philosophers. Nonetheless, a vast number of philosophical works owe their influence and perhaps their greatness to their literary merits.
Philosophers and thinkers
In periods when philosophical speculation became very abstruse, as in Germany in the 19th century, men of letters often acted as intermediaries between the highly esoteric thinkers and the public. Much of the impact of the erudite 19th-century German philosopher Georg Wilhelm Friederich Hegel was due to the more easily approachable writings of those who took issue with him, such as the Existentialist thinker Søren Kierkegaard, or to those who reinterpreted him, such as Karl Marx. Similarly, the thoughts of 20th-century German phenomenologist Edmund Husserl achieved wider circulation by receiving more literary expression in the writings of Jean-Paul Sartre. In modern Europe, the men of letters of Germany were long the most deeply imbued with abstract philosophy. After World War II, however, French writers appeared to take on a zest for abstract speculation, for turgid prose, and for the coining of abstruse terms. Much of French literature in the years after the war has been characterized as “literature as philosophy.”
A very few philosophers have reached greatness by evolving a coherent, comprehensive system, ambitiously claiming to account for the world and man. Such harmonious constructions by the greatest philosophers, such as Descartes and Spinoza, might be compared to epic poems in sometimes embracing more than there actually appears to be between heaven and earth. These philosophical systems were conceived by powerful imaginative thinkers whose creative abilities were not primarily of an aesthetic order. The ability and the ambition to produce such systems has appeared in very few countries or cultures. The Slavic, the Spanish, and Spanish-American cultures have been richer in thinkers than in philosophers; that is, in men who reflected on the problems of their own country, who attempted to evolve a philosophy from history, or who applied a broad view to moral or political questions, rather than in men who constructed abstract philosophical systems.
More and more in the 20th century, the sciences that were called in some countries “social” and in others “humane” replaced the all-encompassing philosophical systems of past ages. In Spain, Miguel de Unamuno (1864–1936) and José Ortega y Gasset (1883–1955) marked the thought and the sensibility of Spanish-speaking peoples far more than systematic philosophers might have done. Their writing, which disdains impeccable logic, is no less thought-provoking for being instinct with passion and with arresting literary effects.
Russian essayists
In Russia, the doctrinal writers whose thought was most influential and often most profound were also those whose prose was most brilliant. They generally centred their speculations on two Russian preoccupations: the revival of Christian thought and charity in the Orthodox faith; and the relationship of Russia to Western Europe, branded by the Slavophiles as alien and degenerate. The consistency of ancient Greek and later Western thinkers, from Aristotle through Descartes, was of scant concern to them, but in the vitality of their style, some of these Russian theorists were masters, whose turbulent, paradoxical ideas were taken to heart by novelists, poets, and statesmen. Among these masters, Aleksandr Herzen (1812–70) combined romantic ardour and positivism, formulating a passionately Russian type of socialism; he left his mark in autobiography, political letters, fiction, and chiefly philosophy of history in From the Other Shore (1851). Nikolay Danilevsky (1822–85), a scientist who turned to philosophy, attempted to convince his compatriots that the manifest destiny of their country was to offer a purer and fresher ideology in lieu of that of the decadent West. V.V. Rozanov (1856–1919) was an apocalyptic prophet preaching an unusual interpretation of Christian religion; a number of his intuitions and passionate assertions are found in the novel The Possessed (1871–72), by Fyodor Dostoyevsky, whose own nonfictional prose is of considerable quality and conviction. The strangest and most contradictory, but also the most brilliant prose writer, among those thinkers who were torn between East and West, between a jealous Orthodox faith and the attraction of Catholic Rome, was Vladimir Solovyov (1853–1900). He blended the most personal type of visionary mysticism with an incisive humour in a manner reminiscent of Kierkegaard. His philosophical essay-dialogue-treatise, Three Conversations on War, Progress and the End of Human History (1900), is representative of the nonfictional Russian prose that, while not widely known outside Russia, is as revealing as the Russian novel of the permanent contradictions and aspirations of the Slavic character.
American and French writers
The role of nonfictional prose in the American literature of ideas is significant, as can be seen in several of Emerson’s philosophical essays and addresses; in Walt Whitman’s Democratic Vistas (1871); in William James’s pleasantly written essays on religious experience and on sundry psychological and ethical topics; in George Santayana’s dexterous and seductive developments on beauty, on nature, on poets, on the genteel tradition, all envisaged with ironical sympathy. Irving Babbitt (1865–1933), Thorstein Veblen (1857–1929), and Lewis Mumford are among the many American writers who, in the 20th century, maintained the tradition of writing on abstract or moral themes with clarity and elegant simplicity. Earlier, Thomas Jefferson and Benjamin Franklin had expressed their lay philosophy in a manner they wished to be widely accessible.
In France the tradition haute vulgarisation—“higher vulgarization” or popularization—never died and was seldom slighted by the specialists. There, and to a slightly lesser extent in Britain, much of the most valuable writing in prose was an elucidation of the view of life underlying the creations of eminent men in many fields. Such doctrinal writing, expounding innermost convictions and sometimes representing a diversion from more intensive pursuits, constitutes a by no means negligible portion of the writings of the philosopher Bertrand Russell, of the poet William Butler Yeats, and others. The novelist or the poet may well use nonfictional prose to purge his own anger, to give vent to his vituperation against his confrères, and to relieve his imagination of all the ideological burden that might otherwise encumber it. D.H. Lawrence preserved the purity of his storyteller’s art by expressing elsewhere his animadversions against Thomas Hardy or Sigmund Freud. Albert Camus stripped his fiction and short stories of the ideological musings found in his philosophical volumes. Marcel Proust succeeded in incorporating many abstract discussions of the value of art, love, and friendship in his very original and loose type of fiction. The masters of nonfictional prose in French in the 20th century were those thinkers who were also superb stylists and who deemed it a function of philosophy to understand the aesthetic phenomenon: Henri Bergson (1859–1941), Paul Valéry (1871–1945), and Gaston Bachelard (1884–1962). No more poetical advocate of reverie arose in the 20th century than La Poétique de la rêverie (1960; The Poetics of Reverie) and the posthumous collection of essays, Le Droit de rêver (1970; “The Right to Dream”), by Bachelard, who was also a philosopher of science. A major influence on him, as on several earlier poets endowed with profound intellect, such as Baudelaire and Valéry, was Edgar Allan Poe, the impact of whose essays on poetics, on cosmology, and on dreams and reveries has been immense and beneficent. More than a century after his death, many of Poe’s American compatriots have conceded that the storyteller and the poet in Poe counted for less, as his European admirers had divined, than the writer of critical and doctrinal prose rich in dazzling intuitions.
