In my contribution, I will introduce, share, and discuss so-called heartefacts - matters of the heart (in German Herzensangelegenheiten) in the sense of embodied aesthetic processes. These hybrid, transmedial works, oscillating between drawing, performance, and matter, emerge from my artistic research practice, which centers on the notation of heart-felt presences. For several years, I have been exploring ways to cultivate an aesthetic thinking-feeling-knowing, characterized by the acts of sensing, registering, and notating sensory-perceptual processes. A central focus is on an empathic and sensitive engagement with the environment - or rather, the Mit-Welt (co-world) - conceived as a reciprocal and contingent exchange. This interaction reveals itself as a tactile sensory experience, a profound state of "being in touch." These atmospheres experienced in this context cannot be understood as separate from the sensing subject but rather as an intrinsic part of an embodied process of perception and meaning-making. I invite the audience to join me in exploring how these "heartefacts" - as material and immaterial traces of an aesthetic relationship with the world - can contribute to understanding and thinking through the lens of cardio-philosophizing.
