When the news of the invention of the daguerreotype left the halls of the French Academy of Sciences in 1839, it fell on the ears of an eager and receptive public, spellbound by the miracle of such an invention. The rapid popularization of the daguerreotype, and subsequently, of less time-consuming photographic processes, forced critics and artists alike to vehemently defend a definition of art that either categorically excluded the new medium or open-mindedly included it within the ranks of a modern or industrialized art. If one maintained, as many did, that the nature and essence of art/literature can be clearly defined and that this definition must be grounded in tradition, coming to terms with what photography was and where it rightfully belonged required either a staunch reaffirmation of one's beliefs about aesthetics or a reassessment of those beliefs. In either case, photography functioned as a disruptive element that did not cause but contributed to an (already existing) artistic movement in which the integrity and solidity of aesthetic definitions and orthodoxies were being questioned and tested. In the minds of those apprehensive and suspicious of the new medium, industrialization, as well as political and social change, had already begun to sound the death knell for art as it had traditionally been conceived. If art/literature had become contaminated by industry, technological advancement and democratic principles, the conservative French nineteenth-century thinker saw it as his duty to save the former from certain destruction. “Saving” art/literature required a fundamental reinforcement of the belief in the closure and soundness of aesthetic definitions whose truth tradition had supposedly guaranteed. Uncovering the presuppositions behind aesthetic definitions that claim to speak in the name of tradition, self-evident truths, and even the nature of man is an endeavor worth pursuing because this manner of thinking leads to a kind of tyranny that has as its goal the suppression of questions, critical inquiry and thus, independent thinking. This study seeks to examine a small part of French aesthetic theory during a period in which change, instability and revolution became almost commonplace. The reactions of conservative artists and critics to post 1840s literary and artistic practices will be scrutinized in order to unveil the deep-seated fears and beliefs that found conservative backlashes to that which is referred to as “new” or “progressive.”
