There is an aesthetic undercurrent traversing Deleuze's philosophy along confluent trajectories of Baruch Spinoza and Friedrich Nietzsche, which harbours untapped potentials and far-reaching consequences for contemporary discussions of art and architecture. According to this subterranean stream, aesthetic experience is generated, neither in ready-made mental faculties of a subject, nor in essential qualities of an object, but through affective interactions of a relational field. A cartographic inquiry of affective aesthetics constitutes the subject matter of this paper, beginning with a philosophical elaboration (...) that connects aesthetic theories of Spinoza, Nietzsche and Deleuze, evolving via a comparative analysis of aesthetic processes specific to Francis Bacon's artistic assemblages and Vogelkop bowerbirds' architectural constructs, and concluding with the possibility of a non-anthropocentric aesthetics.
