The notion of chance epitomizes the limits and challenges of any theory’s struggle for control over itself as well as over its objects. Although contemporary literary theory has adapted its terminology and conceptual framework in line with the emergence of dynamic, “open forms” (Wölfflin in Principles of art history: The problem of the development of style in later art, Dover Publications Inc, New York, 1986), chance has nevertheless remained a highly problematic category to come to terms with. How can literary theory embrace chance? The paper approaches this question in three steps. First, it reconstructs three basic poetological propositions against whose backdrop contingency gains profile: the proposition of causal connections as a means to transform literature into a realm of necessity, the proposition of form as means to reduce arbitrariness, and the proposition of control as a means to protect the aesthetic object against the risks of external intrusions. The second part of the paper discusses a largely forgotten but highly relevant approach to the problem of contingency by Yakov Druskin. Druskin links the function of contingency in theoretical investigation with concepts of contiguity and proximity, first of all touch. His fragmentary sketch of a “law of heterogeneity” represents a paradoxical attempt to theorize contingent obstruction as a privileged systematic device to establish physical contact. The third part of this paper unpacks the implicit urge to rethink the traditions of theory formation itself through the “law of heterogeneity.” It argues that Druskin’s law introduces a different type of theory, one which is deeply indebted to the tactile, thus challenging the ocularcentrism of theoría.
