 Vom Sinn der Liebe (Of the Meaning of Love, 1912) marks Susman’s debut as a philosopher. With this monograph, Susman enters a field of inquiry hitherto exclusively reserved to men; she responds to this challenge by making love the central subject of her investigation. Articulating a metaphysical discourse of her own, she highlights lacunae left by a philosophical discourse determined by male sensitivities. In his essay “The Relative and the Absolute in the Problem of the Sexes” (1911), Simmel had, just a year earlier, analyzed the predicament of the discursive silencing of women, going so far as to cast the understanding of women’s concerns as a sheer cognitive impossibility for the male world (Simmel 1911 [2001 and 1984]). A theory and metaphysics of love, he noted two years later, in “The Problem of Fate” (1913), shortly after the publication of Susman’s monograph, was “just as important as the theory of knowledge and the metaphysics of art”. There, Simmel had wondered where except in the one-sided attempts by Plato and Schopenhauer philosophy had in earnest discussed the question of what is love (Simmel 1913 [2001: 483 and 2007: 78]). The dedication of Susman’s book to Simmel’s wife Gertrud further highlights the philosophical affinity with Simmel and his wife. By taking a subject traditionally deemed a women’s issue seriously and attending to it in a philosophically comprehensive manner, Susman took charge of a subject that since Augustine had been relegated to the domain of theology and since Kant had become a matter of moral philosophy. Neither Kierkegaard nor Nietzsche changed much when they continued to theorize love from a purely male-defined perspective.
