A cyberspace and a cybercrime, acquiring new interpretations by the

means of postclassical methodology, namely fundamental ontology of M. Heidegger,

are analyzed in the article. A cyberspace is understood as a result of «Ent-fernung», that

means the difference between «I» and «you» which cannot be overcomed, and thus this

difference remains on a virtual level. A cybercrime is presented as a direct violation of

possibilities of the Other by limiting his external freedom to act in the cyberspace

according to his existential status.
