In this groundbreaking book, Andrei Pop presents a lucid reassessment of those writers and artists in the late nineteenth century whose work merits the adjective symbolist. For Pop, this term denotes an art that is self-conscious about its modes of making meaning and he argues that these symbolist practices, which sought to provide more direct access to the viewer by constant revision of its material means of meaning-making (brushstrokes on a canvas, words on a page), are crucial to understanding the genesis of modern art. The symbolists saw art not as a social revolution, but a revolution in sense and in how we conceptualize the world. At the same time, the concerns of symbolist painters and poets were shared to a remarkable degree by theoretical scientists of the period, especially by mathematicians and logicians who were dissatisfied with the strict empiricism dominant in their disciplines, and which made shared knowledge seem unattainable. A crisis of sense made art and science look for conceptual foundations underlying the diverging subjective responses and perceptions of individuals.
