Swarms are capable of informing the conceptual field of 'fear' in two ways: Firstly, as space-dissolving diversities that create specific forms of fear and dread; secondly, as spacegenerating collectives whose dynamics become possible only through a fear-induced 'density'. The modes of determination in this field transform themselves from psychological to kineto-physical. And thus, an epistemic alignment is constituted, along which the relations of swarms to spaces facilitate new approaches of media to the conceptual field of 'fear'.
