This text explores the essence of the totality of a living being, which is defined by the fact that all external influences are mediated through its internal, subjective dimension. The author distinguishes between natural influences on the organism and violent interventions that disrupt its integrity. Although a breach of integrity is usually perceived as an attack, in certain situations, particularly in medicine, a targeted disruption of a lower level, such as an organ transplant, may be necessary to preserve the overall integrity of a higher order. A key element of this process is the organism's ability to distinguish between self and non-self, a mechanism that must sometimes be suppressed for the survival of the whole. Totality is thus understood not as a static state, but as a dynamic process in which the subjective aspect determines the boundary between what constitutes the being and what threatens it. This perspective offers a profound philosophical insight into biological identity and the limits of the autonomy of a living subject in interaction with its environment.
