The article focuses on everyday life experience of warfare. The application of the concept of everyday life, taken as a routine reproduction of certain repetitive actions, to the realities of war is understandable, but it suffers from one significant drawback. This drawback lies in the absence of other people's constructive role, which is key for this concept, in everyday actions, while war actions proceed from the need to eliminate the others, to exclude them from the community of “us”. Since the others play a constitutive role for an individual's everyday life, a more closed community, being largely destructive toward others, tends to exclude them. In this case war is the ultimate embodiment of this tendency. Thus, the others, taken as a constitutive force of a person's everyday existence, provide a foundation for ethics, which allows us to talk about the possibility of moral choice during wartime.
